READY GUNNER PURCHASE GUIDE
Radian Ramjet + Afterburner – Sig P365XL (per UPC)
The Radian Weapons RAMJET + AFTERBURNER is a matched barrel and compensator system for the SIG Sauer P365 with the 3.7-inch slide — the P365XL-length platform (the 3.7-inch family also covers the X-Macro and Tac Ops per Brownells). The RAMJET is a match-grade replacement barrel and the AFTERBURNER is a micro compensator, in one threadless system. Radian markets the threadless design as legal for sale in all 50 states (subject to state and local law).
INTRA-LOK Threadless Mounting
There are no barrel threads, set screws, shims, or threadlocker. Radian's INTRA-LOK mounting uses the taper-lock principle: a tapered locking screw interfaces with an angled V-groove on the underside of the barrel, timing the compensator as it locks onto the barrel's profile. The barrel removes from the slide normally for cleaning.
Hardened Stainless, Radianite Black
The AFTERBURNER is machined from hardened stainless steel; the RAMJET barrel is hardened 416R stainless, match-grade, with a gas-sealing chamber. Both carry Radian's Radianite Black coating for low friction, high hardness, and corrosion resistance. Angled front faces on the compensator aid holstering.
