Radian R0834 Ramjet & Afterburner | 9mm | 4.42-inch

The Radian Weapons R0834 Ramjet & Afterburner is a barrel-and-compensator combo designed for Glock 19 Gen4-compatible pistols. It pairs a match-grade 4.42-inch Ramjet barrel machined from hardened 416R stainless steel with a threadless Afterburner compensator machined from hardened stainless, both enhanced with a Radianite surface treatment. The INTRA-LOK mounting system uses a tapered locking screw engaging a V-groove on the barrel for repeatable timing while allowing slide removal for cleaning. Applications include concealed carry setups where slide length compatibility with G17 holsters is desired and controlled-range precision or competitive shooting.
