The Radian Ramjet barrel and Afterburner micro compensator combo is a drop-in upgrade for Glock 19 Gen 4 pistols chambered in 9mm. The Afterburner is one of the smallest pistol compensators on the market at just 0.47" long, yet the two-piece system cuts felt recoil by up to 44% with 115gr ammunition.
The Ramjet barrel is match-grade 416R stainless with a DLC (Diamond-Like Carbon) finish for hardness and corrosion resistance. The Afterburner compensator is hardened 17-4 stainless with the same DLC coating. Together they install on a Gen 4 Glock 19 without any frame work — strip the slide, swap the barrel and recoil assembly, and the package extends the overall slide length to match a Glock 17, so G17 holsters fit the build.
Mounting: Radian's INTRA-LOK system uses a tapered locking screw against an angled V-groove on the underside of the barrel. The compensator self-times against the muzzle face — no shims, no thread alignment to chase.
The Afterburner + Ramjet combo is legal for sale in all 50 states; verify state and local restrictions on compensators before install.
