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 17- 4 SS and the RAMJET barrel from hardened 416R SS; both are enhanced with a DLC (Diamond-Like Carbon) coating. This combination achieves low friction, high hardness, and high corrosion resistance, making overall durability and erosion from muzzle blast a non-issue. 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 G19 , the AFTERBURNER + RAMJET combo increases the overall length of the slide to a G17 allowing compatibility with all G17 holsters. Angled front faces on the AFTERBURNER aid in holstering.
