In this video we are going to use a @SilverbackAirsoft Tac-41P to test the effect of the SB Advanced Piston Head (and its 3 air brakes) on FPS, energy, and sound with different springs. The remainder of the replica will be stock except for the piston head and springs. We will use the stock SB 75N spring and also a SB 150N spring. In addition, we will test a @rapaxsprings4813 2.8J spring.
This is the AEG barrel version of the advanced piston head. We may test the GBB version later on when we change over to the Stalker (@stalkerairsoftdesigns5716 ) Kraken hop up and Morpheus barrel.
