The RadianA(R) AFTERBURNER(TM) + RAMJET(TM) combo provides unprecedented recoil reduction and match grade accuracy in a concealed carry package. The threadless barrel design allows for repeatable, effortless installation and removal for cleaning. The AFTERBURNER(TM) compensator is machined from hardened 17- 4 SS and the RAMJET(TM) 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-LOKA(R) mounting system uses the taper lock principle; a tapered locking screw interfaces with Mfg: Radian Weapons
