The Radian AFTERBURNER + RAMJET combo pairs match-grade durability with real-world concealment practicality. A hardened 416R stainless RAMJET ported barrel and a stainless AFTERBURNER micro-compensator are both treated in Radianite(TM) for low friction, high hardness, and exceptional corrosion resistance engineered to resist erosion from repeated muzzle blast. The threadless INTRA-LOKA(R) taper-lock mounting system makes installation and removal simple, repeatable, and holster-friendly: slide the comp on, tighten the tapered locking screw into the V-groove, and the compensator times itself perfectly every time. Installed on a GlockA(R) G19 the combo extends slide length to G17 dimensions for broad holster compatibility while remaining legal for sale in all 50 states.* Specifications: Includes: (1) RAMJET(TM) ported pistol barrel, (1) AFTERBURNER(TM) micro-compensator, (1) INTRA-LOKA(R) tapered locking screw, (1) TORX bit Barrel Material: Hardened 416R stainless steel (ported) Compensator Material: Stainless steel (AFTERBURNER(TM)) Coating/Finish: Radianite(TM) low-friction, high-hardness finish on barrel & comp Mounting System: INTRA-LOKA(R) taper-lock (threadless) - tapered screw into V-groove for repeatable timing
