ABOUT KAC SR 15 14.5 UPPER

The finely tuned mid duration gasoline method of your SR-15 E3 Mod2 provides specifically plenty of gas to reliably cycle the process with no excess gas which can foul internals and burn up the operator’s eyes even when suppressed. This wonderful tuning also contributes to a flatter shooting rifle using a softer recoil impulse than a typical AR.
