AFTERBURNER + RAMJET together reduce recoil up to 44% when using 115g ammunition. At only .47" long, the AFTERBURNER offers unprecedented performance in a micro compensator and is more effective than the majority of full-size compensators on the market. The INTRA-LOK mounting system uses the taper lock principle: a tapered locking pin interfaces with an angled V-groove on the underside of the barrel. This perfectly times the compensator as it locks down onto the V-shaped profile on the muzzle end of the barrel. Angled front faces on the Afterburner aid in holstering.
