THE 5-SECOND TRICK FOR KAC SR 15 14.5 UPPER

The finely tuned mid duration gas procedure of the SR-15 E3 Mod2 delivers precisely adequate fuel to reliably cycle the system without having extra fuel that can foul internals and burn up the operator’s eyes even when suppressed. This fantastic tuning also results in a flatter capturing rifle which has a softer recoil impulse than a typical AR.
