Radian Weapons Afterburner + Ramjet for Sig P365XL 3.7in

The Radian Weapons Afterburner + Ramjet is a combo barrel and compensator package engineered to reduce perceived recoil and support match-grade accuracy in a compact, concealed-carry-compatible footprint. It pairs a ported RAMJET match-grade barrel with an AFTERBURNER micro-compensator and uses a threadless, INTRA-LOK mounting system for repeatable, tool-assisted installation and removal. The barrel is manufactured from hardened 416R stainless steel and both components are finished with Radianite for corrosion resistance and surface hardness.

The INTRA-LOK taper-lock system times the compensator to the barrel using a tapered locking screw that interfaces with a V-groove on the barrel underside, allowing the compensator to slide over the barrel and be secured without permanent threads.

The result is a practical upgrade for shooters who want improved muzzle control and a holster-compatible slide length when installed on compatible P365XL platforms.
