The Radian Afterburner + Ramjet is a matched ported barrel and compensator system designed to keep your sight picture flat when it matters. This combo delivers what high-end compensator setups promise: measurable recoil reduction without sacrificing the carry-friendly profile that makes modern duty guns useful.
The Ramjet is machined from hardened 416R stainless steel and ported along its length to work in concert with the Afterburner compensator. The barrel is match-grade by design, and the porting isn't random venting, it's engineered for the specific gas dynamics the Afterburner's ports need. You get a fluted profile for weight savings and a gas-sealing chamber that pressurizes the gases properly for the compensator to do its job. There's also a loaded chamber indicator built in and the barrel measures 4.9 inches. When dropped into a Gen6 G19, the combo extends your slide length to G17 dimensions, which opens up your holster options without actually changing your pistol's size.
Instead of threading the barrel and fighting timing issues or screwing with crush washers and shims, Radian's INTRA-LOK system uses a tapered locking screw that sits in an angled V-groove on the barrel's underside. The screw clamps down with a simple 15 in-lb torque spec, and the taper geometry does the timing for you. Installation takes minutes, no gunsmith needed. More importantly, the locking screw doesn't sit in the blast path, so carbon buildup won't freeze the system even after thousands of rounds. Field stripping for cleaning is tool-free and repeatable.
Both components are finished in Radianite, Radian's proprietary low-friction, high-hardness coating that resists muzzle blast erosion and corrosion. The Afterburner compensator is CNC-machined hardened stainless steel with angled front faces that guide into your holster smoothly. Real-world data shows the combo reduces felt recoil by up to 44 percent with standard 115-grain ammunition. That translates to flatter muzzle rise, faster sight acquisition, and better follow-up shots without fighting recoil management.
The combo increases your G19's slide length to G17 dimensions, so it'll fit any G17 holster. For G45, you're at full size already and existing holsters should accommodate it. That said, double-check fit because some carriers run tight. The angled front face of the Afterburner is designed to guide smoothly during holstering, but holster compatibility always depends on your specific setup.
Yes. The threadless design means you don't need tools to remove the barrel from the slide during a field strip. The INTRA-LOK screw is torqued to just 15 in-lb and sits away from the blast area, so carbon won't seize it even after high round counts. Clean the bore the same way you'd clean any barrel, and if you run high volume, apply a light coat of heat-resistant oil between the barrel and compensator to prevent carbon lock.
Radian rates the combo at up to 44% recoil reduction with standard 115-grain full metal jacket loads. Performance varies slightly with ammunition weight and powder burn rate, but shooters generally report significant muzzle rise control across common duty rounds. Some edge cases with lighter loads or specific ammunition types can require a break-in period, but most see reliable function out of the box.
No gunsmith required. Installation is a simple field strip, drop the barrel in place, slide the compensator over it, and tighten the locking screw with the included TORX bit to 15 in-lb. The INTRA-LOK system handles timing automatically, so there's no shimming, indexing, or Loctite needed. Takes about five minutes from start to finish.
