Radian Weapons AFTERBURNER RAMJET Fits Glock 19 Gen 4 9MM INTRA-LOK Mounting System Black Finish R0874 UPC 810098421058
Product Description
The Radian Weapons AFTERBURNER + RAMJET Combo (R0874) is a revolutionary match-grade barrel and micro-compensator upgrade system engineered specifically for Glock 19 Gen 4 9mm handguns. Designed to deliver flat-shooting performance without the legal complications or length penalties of traditional threaded barrels, this combination reduces felt muzzle recoil and muzzle climb by up to 44% while maintaining a total length profile that fits standard Glock 17 open-ended concealed carry holsters.
The core of the system is the precision-fluted Ramjet match barrel, forged from hardened 416R stainless steel and finished in an ultra-tough black DLC (Diamond-Like Carbon) coating. The Afterburner micro-compensator attaches via Radian's patent-pending INTRA-LOK mounting system—a taper-lock interface that secures the compensator directly onto an engineered notch on the unthreaded barrel using a single Torx locking screw. This design eliminates the need for thread lockers, shim sets, or set screws while ensuring 100% concentric alignment.
Because the Ramjet barrel features a non-threaded muzzle end, the Afterburner combo is 50-state legal, making it compliant in jurisdictions that restrict threaded barrels on semi-automatic handguns. Engineered and manufactured in the USA, it provides an incredible performance edge for EDC, competition, and tactical applications.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits Glock 19 Gen 4 handguns. (Not compatible with Gen 3, Gen 5, Glock 19X, or Glock 45 models due to guide rod notch geometry).
- Perform a complete firearm safety check: drop the magazine, lock the slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- Field strip the Glock 19 Gen 4 slide assembly and remove the factory barrel and recoil spring assembly.
- Insert the Radian Ramjet barrel into the slide cavity, ensuring proper lockup into the ejection port.
- Slide the Afterburner micro-compensator over the muzzle end of the Ramjet barrel, aligning the INTRA-LOK taper pin hole with the barrel notch.
- Insert the included INTRA-LOK mounting screw and torque to 15 in-lbs using a precision inch-pound torque wrench and T15 Torx bit (do not apply thread locker).
- Reinstall recoil spring, reassemble slide onto frame, and cycle slide manually to confirm smooth lockup and slide function.
