The Radian Weapons Afterburner + Ramjet Combo for Glock 19 Gen 3 pairs a threadless Ramjet pistol barrel with an Afterburner micro-compensator (Radian part no. G19G3-IL-RN). Radian machines the Afterburner from hardened stainless steel and the Ramjet barrel from hardened 416R stainless, and both carry its Radianite coating for low friction and corrosion resistance. The Intra-Lok mount slides the compensator over the barrel and times it with a tapered locking screw, so the barrel comes out of the slide for cleaning without any muzzle threads in the way. This is the Gen 3 version, a recoil-control upgrade for concealed-carry and range pistols that adds match-grade accuracy without a threaded barrel. Radian Weapons builds it in black.

Key Specifications
