Radian Weapons Afterburner + Ramjet for Sig P365XL, 9mm, 3.7″

The Radian Weapons Afterburner + Ramjet is a barrel and compensator combo designed to reduce recoil and deliver match-grade accuracy in a concealed-carry package. The Ramjet barrel is manufactured from hardened 416R stainless steel and the Afterburner compensator is machined from stainless steel; both receive a Radianite coating for corrosion resistance and low friction. The kit uses a threadless, INTRA‑LOK mounting system that employs a tapered locking screw and V-groove to precisely time the compensator and permit straightforward removal of the barrel from the slide for cleaning. When installed on compatible slides, the combo increases slide length to P365XL dimensions for holster compatibility.
