The AFTERBURNER(TM) compensator is machined from hardened stainless steel and the RAMJET(TM) barrel from hardened 416R SS; both are enhanced with a Radianite(TM) coating. This combination achieves low friction, high hardness, and high corrosion resistance, making overall durability and erosion from muzzle blast a non-issue. Angled front faces on the AFTERBURNER aid in holstering. The INTRA-LOKA(R) mounting system uses the taper lock principle; a tapered locking screw interfaces with an angled V-groove on the underside of the barrel. This perfectly times the compensator as it locks down onto the upper barrel profile on the muzzle end of the barrel. INTRA-LOKA(R) allows the user to simply slide the compensator over the barrel, insert and tighten the locking screw, making for a simple and repeatable installation process. This system allows the user to easily remove the barrel from the slide for cleaning. Installed onto a Glock(TM) G19(TM), the AFTERBURNER(TM) + RAMJET(TM) combo increases the overall length of the slide to a G17A(R) allowing compatibility with all G17A(R) holsters. This combination kit is for: GLOCK(TM) G19 Gen 5 / G19X(TM) / G45(TM) (or compatible)
