Radian Ramjet + Afterburner: Effortless Accuracy, Mega Recoil Taming

The Radian Ramjet is a 3.1″ 416R stainless steel barrel for the Sig Sauer P365 pistol. It features a match-grade, cut-rifled bore, and black DLC coating. The Afterburner micro compensator threads onto the barrel using Radian’s INTRA-LOK taper-lock mounting system with no need for loctite or shims.

The Afterburner is machined from 17-4 stainless steel and has angled front faces to aid holstering. When combined, Radian states the Ramjet barrel and Afterburner compensator reduce recoil by up to 44% when firing 115 grain 9mm ammunition compared to a standard P365 barrel.
