I built an AR from scratch and am very satisfied with the results. I got what I wanted and saved some money in the process, plus the satisfaction of building it myself. My design objective was to have a lightweight general purpose AR. The parts I chose were: Faxon 16" match grade pencil barrel (Wylde 223 chamber) Faxon bolt and carrier Aero Precision upper and lower (I lapped the upper seating surface) Geissele trigger Midwest free float M-Lock rail Brownells buffer and spring Raptor LT charging handle Daniel Defense adjustable stock (a lightweight model) Trijicon red dot sight The rifle is nice and light and more than accurate enough for my needs. I have not experienced a single malfunction while shooting this AR.

I'm a cnc machinist. Every part has a spec and a tolerance, usually +/- .005. Just because you was a thou and half diffent this time doesn't mean you will be next time using the exact same brands and parts. If you pins could be polished a little using a drill and a scotchbright pad, maybe try to use a little heat or put a part in the freezer to get them to expand or contract a little. A good press finish can easily be .001 inches difference in the pin and hole size

Over the last 45 years, I've built dozens of ARs to different spec-levels, from precision DMR's, to hunting, to SHTF grab-and-go's, to truck-gun pistols, etc. I'm sorry you've had challenges with your builds but I'd like to emphasize to those who may be thinking about building their very own 1st AR-GO FOR IT!!! Just do your due diligence, research parts and suppliers, determine WHAT you're building your AR for-FIRST. Is it for home defense, hunting, SHTF, plinking, truck-gun, etc.? It's a very rewarding experience-every time you complete one and test-fire it successfully!

Yes, I totally agree with you. I built 4 AR's in 2019. I built Two using .223 Wylde gun barrels, one a 16 inch and the other a 7.5 inch. I also built two AR9's, a 16 inch and a 7.5 inch. Two pistols & two carbines. All four worked flawlessly and I had a lot of fun building and shooting them. I didn't use any Brand name Tactical parts to keep the cost down and everything fit together with no issues. I'm a machinist like one of the others who commented here. Everything has to be within tolerance and that's what Mil-Spec means to me. Mil-spec isn't bad or substandard, and who's to say a Tactical brand part is any better than the next. I didn't set out to make the most accurate AR's, I did a good job, had fun, and these were the first AR's I've ever built. They work good enough for me and that's what matters at the end of the day. Having to heat the upper receiver to shrink fit the gun barrel doesn't sound correct to me. All four gun barrels I bought fit perfectly into the uppers. None were loose and none had to be forced in, they were a nice slip fit, just the way you would expect them to fit. In other words, the O.D, of the gun barrels and the I.D. of the uppers were the correct size and fit properly together.

I just built my first AR-15 about 4 months ago. I built it on the cheap (under $600 I believe) mostly because I shopped for weeks trying to find well rated parts on sale (President's day and Memorial day sales were amazing LOL). The build was a total pain in the ass, and at times frustrating to the point I almost quit and took it to a local gun smith to finish it. That being said it was one of the most rewarding experiences I've had of late, because I LEARNED SO MUCH about the rifle and the mechanics behind it. If you are the type of person that like to take their rifle/pistol to the range a couple of times a year, just go buy a completed rifle, but if you're the type of person that wants to UNDERSTAND what is in your hands, WHY it works the way it works, and be able to fix minor issues yourself when they come up, then there is absolutely no substitute for building your own rifle!

Assuming your optics are correctly and securely mounted, I would re-torque the barrel nut. Make sure when you bring it up to its final torque spec, you back it off, then tighten it to that same torque spec two more times. Remember, the minimum torque value is 30, the maximum is 80 “-ish”. There are various schools of thought on what the correct torque value final setting is, but whatever you go with, it should be different than what you’re using now as it has proven to not work with your gun. Make sure to put molybdenum grease on the threads of your receiver and your barrel nut, and on the barrel extension. The other thing I would do, is to try out various muzzle devices. Muzzle device is add mass to the barrel, which affect the harmonics/accuracy. Unless you have a muzzle device that can be tuned to the harmonics, you’ll just have to try different ones until you find the one that works best with your rifle and a given load.

I don’t think there’s anything wrong with building your own AR. But I personally wouldn’t do it. Building an AR is more than just putting parts together. Building an AR takes time to perfect. There’s trial & error that you have to do before you find the parts that are compatible & finding parts that make each other better. Kinda like a team. Each part plays its role in the function of the AR. And if one part doesn’t function right. The whole rifle don’t function right. That’s why you have these big names like Daniel Defense, BCM, or whoever else Like I said, I don’t think anyone is in the wrong if they choose to build an their own AR. Just know & respect that it takes more than piecing parts together to build an awesome AR.

I have three AR builds with Criterion barrels. 20" heavy barrel, 16" and 18" Hybrids and all of them using VG6 Epsilon muzzle devices. They are all parkerized, chrome lined and Wylde chambered. They all shoot sub-MOA with the 20" being the tack driver. I have used off the shelf non-match 62 grain non-steel core 223 and 55 grain 5.56 NATO so far. One of Criterion's co-founders is John Krieger of Krieger barrels and I believe he is still part owner. If you believe the barrel is the issue I would call them. I don't know if they put it in writing anywhere but I think it's generally accepted that Criterion should shoot sub-MOA.

Only downer I ran into, was no open notch rear sight to be found, and my eyes don't do the peep or red dot stuff. Bifocals and astigmatism, so I need rear sight far forward. In the end, I stuck a low profile scope on, and cut down sight tower. Went with nitride Nato/multi 16" barrel and 1:7 twist was the cheapest. Classic handguard, nothing fancy.

I love building ARs. I bought my first one Aero AR X-15. Then loved the platform so much , I wanted to try and build my own. The first build I was a wreck. Scared, nervous, full of “What ifs” etc. it was the best learning Experience possible, from securing the bolt release, trigger guard (without breaking the lower ), to the 3 times I accidentally slipped and got hit in the head by the Stocks detent and spring. List 3 detents , broke a few springs, and there is I’m sure a detent and spring still hasn’t come down into the atmosphere yet. I was smart and ordered extra parts before starting. I stuck with all Aero precision parts due to knowing and trusting the brand. Nothing puts fear in you like shooting your first round on your first build. 🤣, once everything worked I fell in love. Now I build and add higher quality parts on my rifles regularly. I finally built an Aero M5 308 which was amazing. I can spend 4-9 hours in one sitting and not even realize the time.

And if I did screw it up it would not have cost THAT much. I purchased all parts way before the corona virus. And by purchasing individually I opted to the get all upgraded items. It turned out wonderfully. I shot very well and just as good accuracy as my Colt 6920. Maybe that had to do with the CHF FN barrel I opted use. What really makes me proud is that I put that rifle together myself. So yes I am glad that I did. Now I did purchase the A2 front sight post already installed. That I wanted perfectly aligned. So I might have cheated a bit but still it is a rifle that I put together and proud of it. Newbies....you and I both did not want to mess with the gas block! I as well had to purchase a torque wrench. Never used one and I only used it once Ha! I would take the barrel off and re-install it. You never know...maybe it was not torqued enough. Who knows but I would re-install the barrel. Not much more you can do to the rifle more accurate. It is combat accurate though! Hoo-Yah. USNavy.

When adding a muzzle brake I always use shims rather that a crush washer. A crush washer can cause the muzzle brake or flash hider, not as important as a brake to have indexed right and straight, to not be perfectly straight. This includes issues with threads on the muzzle brake or on the barrel. Another thing to remeber is even though you can shoot 223 out of a 556 barrel the 223 will not be as accurate. Looking at the wylde barrel’s it’s the opposite the 556 won’t be as accurate. Ammunition weight and turn and length of barrel also has huge impact on accuracy. Make sure your shooting the right weight and type to the barrel you have. Verify the head spacing as well. You could be in tolerance but on the loose side of it that combined with say an out of tune muzzle brake could give you the wider grouping at range.

I have two rifles I have built, sort of. I built both my lower receiver assemblies from stripped lowers so that I could pick my own trigger, stock, and pistol grip, but I bought complete uppers from BCM, because after a lot of research and the fact that I don’t have the necessary tools to build an upper from scratch, I determined going with BCM would give me the quality I was looking for without the hassle. I haven’t been disappointed. I may try building my own upper assemblies at some point in the future if I acquire the right tools. Regarding accuracy, have you heard of David Tubbs? Accuracy is his thing and he has some excellent KZitem videos. I bought some of his flatwire buffer springs and have been very satisfied with them. He has an informative video explaining why they are superior to the standard mil-spec buffer springs, and vast knowledge of all the tweaks you can do to wring the most accuracy out of your rifle.

A2 front sight post, and a decent, metal rear sight that came with the upper. I did put on an inexpensive 3-9 scope for when I don’t want to try so hard! (My wife shot it for the first time recently, and with the scope, had no problem with 200-she’s all of 5 feet and 97 pounds!). Of course, I had to show off and hit without the scope!

Pull and lock the carrier to the rear. Slam a round home. And then eject the round and look at the bullet for marks. I don't know how expensive your barrel was. But maybe a feed ramp shave and polish might do something. Assuming the headspacing and throat gap is all on point. And when you start playing with muzzle devices you are playing with barrel whip and harmonics. Most of the time a brake will enhance performance. Little bit more bark at the shooting pos. Lol. Nice looking gun though.

Your supposed to tighten the barrel in 3 steps,(use anti-seise) if you want 45 lbs total , first tighten to 30lbs , second time add 6 pounds more =36 , third time 6 pounds more=42 , your final time go to 45lbs . The reason for doing this is , it matches up all the thread surfaces so you have even pressures , it marrys everything up evenly together . It might sound stupid but I watched a Master builder explain it just like I did too you . Just do it ! If your group are bad and you check everything else , it's most likely the barrel nut not staying tight , even though it felt tight it wasn't seated right, it effectively gets loose because it wasn't fully seated properly ! One guy talks about some parts being heated I have heard that too , like when installing a taper crank shaft into a flywheel on a H.D , some AR barrels are done that way it depends on the type assembly and method, Black shadow rifle's company uses a tapered fit receiver in that case they use that method.. hot receiver and cold barrel tapered compression fit.

Without the gauges and tools to test parts, it can be a game of luck if the parts are suitable or within spec. I have seen barrels, receivers, gas blocks, bolts, etc that have been on opposite ends of quality and spec from the same manufacturer. The manufacturer can improve those odds but not always..Mil spec means a part is manufactured within a set of tolerances set by the military TDP for reliable function. Many parts claiming to be mil spec are not.. Geissele and LaRue pins should be.1551 , Colt should be .1539..There is a way to oil lap the lower receiver fire control pin holes for fitting tight trigger and hammer pins. Always head space the bolt and barrel being used. Checking the throat and chamber with a PTG chamber function gauge is a must too in my opinion.. Barrel quality, upper receiver bolt carrier fit are imperative to accuracy.. A loose bcg upper receiver channel will kill accuracy..Lapping the upper receiver has dramatically increased accuracy for some of my rifles and also has had very little to zero perceived accuracy improvement for other rifles..I can say my Geissele upper receivers have been fantastic for their bcg channel, barrel fit machined dimensions and tight fit with my lower..

Did you lap the barrel seating surface? if the barrel extension and upper receiver aren't square to each other and seated well, you can get inconsistent accuracy. The face of the upper receiver might not be perfectly square which can cause uneven pressure against the mating surface of the barrel extension. This condition can cause the resonance of the barrel to change slightly causing the point of impact to shift.

I too built my first AR a while back and now built my third one. I love your honesty. 🤣 My first build was a .300 BLK that had numerous problems. I learned much from that one about dwell time and port sizing. I spent many hours watching video's and reading about the gas system of an AR and how it works. It would tear the rim off the case trying to eject the case that would not come out of the chamber. I polished the chamber and changed powders and tried different loads. I finally got it to work but eventually sold it. My next one was a 5.56 18 inch 1-8 twist Mark 12 Mid length barrel that wouldn't lock back on the last round. I finally had to increase the powder charge and shoot 62 grain bullets to get it to work. It liked hotter loads. I could have drilled out the port some but decided not to as it finally started to work well enough to leave it alone. My last one is a .223 Wylde 16 inch 1-8 Stainless spiral fluted carbine length gas port barrel that had some early issues. The chamber throat was not reamed enough to take a factory bullet. I had to obtain a chambering reamer and correct that myself. It works fine now and is quite accurate. The journey through all this has taught me considerable and if a person values that then it was definitely worth it. If a person doesn't value the learning process it's best to just go out and purchase what you want and be done with it but I wouldn't want it any other way than the way I did it. 😁

Lapping an upper is an amazing technique when looking for tight and consistent groupings. I had a Smith and Wesson sport 2 that I purchased back in 2014. I stopped shooting it In 2016. As years kept passing by, I would buy parts here and there so that one day I could give it a 21st century face lift. All the parts I bought was with the purpose to run it suppressed. In Aug 2021 I got my first tax stamp approved for my dead air wolf man. Just 3 weeks ago I tore that sport2 and installed all the parts I have collected over the years. I did update the upper reciver to an Aero M4E1 threaded upper. Dropped in a bootleg BCG for suppressor settings depending on CAN flow and ammo type. Kept the stock 1/9 twist berral but I did lap that Aero reciver before I installed the berral and nut. Once the build was complete I took it to an indoor range here in Orlando that gives me 100 yards. Sighted in different optics that I have and both in 25 and 100 yards I'm getting stupid tight groups. Now if I'm using my LPVO the groups are practically sub MOA from 25 to 70 yards

It's going to take a long time and you need to be patient and wait until you can either get the part you want or scour the internet to find someplace that has it. I ordered a handguard with the wrong rail- had to send it back and wait another month. It could have worked just fine, but if you are going to tailor a gun to you, it's not going to feel good when you dont get exactly what you want. It's a one-of-a-kind gun built for you, by you.

This is kind of bank breaking but super expensive parts are always going to fit and work which sucks when youre trying to do a budget build. Triggers is luck of the draw if you can fire once and it cant shoot again its most likely a buffer weight/spring or gas port issue thats why a lot of people opt for an adjustable gas block it fixes both problems.

I’ve built a few AR’s and use Criterion barrels and Badger Ordinance TGX gas manifold (their name for gas block) I use red locktite around the barrel (to seal it) and Rocksett on the screws……. I’ve herd people say pinning gas blocks can effect barrel harmonics and can effect accuracy at longer ranges….. my 18” and 16” will make Dime size 5rd groups with match ammo consistently even with my 12.5 getting about 3/4” groups………. Criterion has a build series that’s pretty good…… check your barrel torque keep above 50 ft lbs and make sure you head space your bolt. Use the heaviest buffer you can and function correctly keeping the brass in the chamber a mili second longer could help. Try shorting with no muzzle devise as well to see what accuracy you get then. I’ve also found with Criterion barrels keeping muzzle vel around 26-2750 with 77gr gives you best groups…… Non of my Criterion barrels like 75gr but love 77 and 68.

I think I'm about to build a Wilson Combat AR. I've been shooting ARs since 2006 and have never built one. BTW: red locktite will release under heat. If you can heat up the receiver, you can release red locktite. Blue locktite will back off. When you put the butane to that receiver, it more than likely warped the receiver. There is no way that barrel went in square. Even a slight cant in the barrel can alter the head space and effect terminal accuracy. It's a common problem when people re-barrel Ruger 10/22s. If you want to know if the comp effected the groups, take the comp off.....

I don't see the advantage of heat shrinking the gun barrel into the upper receiver. I feel as long as the barrel nut is greased, and torqued to the proper foot pounds, and released and re-torqued 3 to 4 times, the receiver threads will be properly stretched and the gun barrel will be properly fitted and as tight as it has to be. Then it comes down to properly mounting and leveling your optic to the upper receiver, and sighting it in to the degree you need to get the job done.

I would recommend to anyone to build an Ar-15 but only after learning how each component works and how they all work together’ especially the gas system. I watched YT videos for about a year on assembly’ trouble shooting’ ejection patterns and each component so that I understood how everything worked and what I was doing to assemble. My first build was a budget build that costs about $650 with optic and mount. It came in at 8.5lbs and it could shoot under an inch if I did my part. My wood shop teacher always told us “If you fail to Plan’ Plan on failing” and I apply that logic to everything I do I life. The only thing I didn’t like about that first build was the weight and I don’t consider that a fail because I didn’t plan on building it lightweight. Since then I’ve built over 30 Ar’s from .300blk .223/5.56 .308 and 6.5cm from regular weights to ultra ultra lightweight. My first Ar I owned was an M&P 15 which was nothing special but it ran great. The real advantage to building your own Ar is you get to pick the parts you want and as your budget allows. one of my Ar .308’s weighs 4lbs 14oz with a 16” barrel 15” handguard and rifle length stock. It shoots under an inch and has no cycling or ammo issues. It cost about $3000 over 2 years ( mainly because parts were out of stock ) but I could afford it over time rather than all it once. Im still learning about Ar’s and I by no means think Im an armorer or a gunsmith. I don’t work on other peoples guns or act like a know it all. As far as the accuracy issues your having I would contact the barrel manufacturer and ask them what you should do’ maybe they’ll exchange it or have you send it in for testing. Good luck.

@@PracticalAccuracy runs smooth and dependable, like it was meant to. Very fast and accurate. Took a bit of experimenting with bcg’s, the short dwell time of the intermediate gas length does not like lightweight bcg’s. Something to keep in mind and thankfully I have lots of them to play with.

@@PracticalAccuracy It's been close to a decade since i investigated making a super accurate upper. So take this with a grain of salt. The scuttlebutt from one uber premium barrel maker was his recomended gas blocks were clamp on style. he claimed something about barrel harmonics or what not. I don't buy it for a second. the next build you do try a faxon or ballistic advantage. Both can be had with a pinned gas block. I have a 18 inch faxon and the limiting factor is me not the barrel.

Check barrel nut again for proper torque, along with your scope mounts which I’m sure you did fine you seem competent. That’s about all I can say if not I’d say send the barrel back to criterion it sounds like you did everything right not sure why it turned out opposite of your initial intentions. but hey ya win some and loose some. either way still a nice perfectly serviceable rifle! sounds like it will have no issue shooting minute of man if need be!

Hell YES it was, at least for me, plus I saved some good $$$. I've built 3 now in the last year, 2 were 5.56 and the last is 6.5 Grendel. I thought about doing the Creedmor but just wanted to do something different and wanted to stay in the caliber that already have the lower ( bought several when they were cheap. I enjoyed just about everything about doing the builds from anticipating the receipt a the parts to decking the finished projects with decorations. Now I want to build a 10 in maybe a 308 or 30-06.

Interesting video I had never shot a AR style rifle and wanted to try building (assembling ) one but I also wanted to see how cheaply I could get one done. I do realize quality parts are most likely to last longer but having a running firearm was my goal. I did a poly. 80% lower and using my drill press and a XY vise and a lot of luck then a lower build kit one company and a upper receiver from another a barrel from yet another and hand guard gas block gas tube etc etc. till I had everything . It shoots 1 inch groups so I am happy. As far as you'r trouble with one of those you showed take into consideration you'r twist anything slower than 8:1 most likely will not shoot over 68 gr. Keep on tryin man and keep us informed .

Thanks for watching. I don't have any experience with them so I can't offer muchb assistance. I can only say that I chose BCM because I wanted to heat fit the upper to the barrel for a tighter fit. There are other companies as well that do this, but I chose BCM. Good luck with your build.

The only thing I see wrong with that gun you built, is that scope, get a LPVO and its perfect. LPVO will allow close quarters up to 600 meters. Giving you advantage from short to long, other than that is perfect

I did not see your full parts list or know of your mechanical skill set. Having said that, have you hand lapped the upper receiver? Also for maximum accuracy, did you carefully, target match style, break in your barrels? What is the twist rates for your barrels & what weight rounds are you using? If you are using 1:7 twist rate barrels, try using 75+ grain Hornady match grade ammo. If you are using 1:8 or even 1:9 twist barrels, use 62-68 grain Hornady ammo. Stay away from steel core ammo. For lube, just use automotive/motor full synthetic oil. Good luck! Nice video.

@@PracticalAccuracy It's too bad that you have non-spec upper receivers. The price of a AR Lapping tool is less than $50 & the lapping compound is less than $10. After that, all you need is a drill. It's super easy & fast to do. You don't actually remove that much metal. With your tight uppers, it would be a pain to keep using a torch on the upper just so the tool can fit & spin. Consider getting a Right To Bear Nickel Teflon Upper Receiver($99 when on sale), the rails on which the BCG rides is coated in super slick Nickel Teflon. The track that the charging handle rides is also coated making for smoother use.

Are you thinking about building your first AR? May I suggest first canvassing your friends and family for those who may have done it before you. That will likely save you some money in the purchase of required tools. One other thing I (having just completed my first build) will warn you about. As soon as you have finished your first one, you will absolutely be thinking about your next one. BEHOLD another build addict!
