The Radian AFTERBURNER + RAMJET combo offers an unmatched combination of recoil reduction and match-grade accuracy, all in a convenient concealed carry package. Its threadless barrel design ensures an effortless installation and removal process for easy cleaning, while being fully legal in all 50 states. Precision-crafted from hardened 17-4 stainless steel, the AFTERBURNER compensator, paired with the RAMJET barrel made from hardened 416R stainless steel, guarantees exceptional durability. Both components are treated with a Diamond-Like Carbon (DLC) coating to provide low friction, high hardness, and excellent corrosion resistance, making them resilient against erosion from muzzle blast. The INTRA-LOK mounting system, based on the reliable taper lock principle, features a tapered locking screw that interfaces seamlessly with an angled V-groove on the underside of the barrel. This ensures perfect timing and secure locking of the compensator onto the upper barrel profile at the muzzle's end. The user-friendly INTRA-LOK system lets you simply slide the compensator over the barrel, insert and tighten the locking screw, allowing for a straightforward and repeatable installation process. This design makes it easy to remove the barrel from the slide for cleaning whenever needed. Specifically designed to fit a Glock G19, the AFTERBURNER + RAMJET combo extends the overall length of the slide to match the G17, ensuring compatibility with all G17 holsters. The angled front faces on the AFTERBURNER also facilitate smooth holstering. Before installation, it's advisable to review your state and local laws to ensure full compliance with regulations in your jurisdiction.
