On this episode, Seth is joined by fellow marketeer, Judd Jarzynka, and Project Engineer, Miles Neville. The conversation dives deep into the AR-15 direct impingement system; specifically, the importance of gas system tuning. Shorter barrels, suppressors, and subsonic ammo can affect how an AR-15 functions. The guys share their experiences from a number of AR builds – there is no one way to tune them all. We hope you enjoy the show!
