Radian Weapons R0884 Ramjet + Afterburner Combo Fits Glock 17 Gen 4 Black Porte - 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. The AFTERBURNER compensator is machined from 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. 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.
