The Radian® AFTERBURNER + RAMJET combo provide unprecedented recoil reduction and match grade accuracy in a concealed carry package. The threadless barrel design allows for effortless install/removal for cleaning while LEGAL FOR SALE IN ALL 50 STATES*. - The AFTERBURNER compensator is machined from hardened stainless steel and the RAMJET barrel from hardened 416R SS; both are enhanced with a Radianite 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-LOK® 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-LOK® 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 G17 the AFTERBURNER + RAMJET combo only increases the overall length of the slide by .47 allowing compatibility with all G34® holsters. - Engineered specifically to run 124 grain and heavier 9MM ammunition. - This combination kit is for: GLOCK G17 GEN5 / G47 / G49 (or compatible) - AFTERBURNER / Hardened SS - RAMJET-SR / Hardened 416R SS - Match grade barrel - Gas sealing chamber - Loaded chamber indicator
