The Radian Weapons Afterburner + Ramjet kit provides a threadless, ported barrel and micro-compensator designed for the Sig Sauer P365XL and P365-XMACRO 3.7in slide. The Ramjet barrel is manufactured from hardened 416R stainless steel and the Afterburner compensator is machined from hardened stainless steel, both enhanced with a Radianite coating for improved hardness and corrosion resistance. The INTRA-LOK taper-lock mounting system enables a repeatable, tool-assisted installation while allowing the barrel to be removed from the slide for cleaning.
Installed on a compatible 3.7in slide, this combination extends the slide length to match P365-FUSE dimensional compatibility and is intended for concealed-carry setups where reduced muzzle rise and controllability are desired. Not available for direct ship to California as noted in the manufacturer data.
