The RADIAN® AFTERBURNER + RAMJET combo provide industry leading recoil reduction and match grade accuracy in a concealed carry package. The threadless barrel design allows for effortless install/removal for cleaning while LEGAL FOR SALE IN ALL 50 STATES. – The AFTERBURNER compensator is machined from hardened stainless steel and the RAMJET barrel from hardened 416R SS; both are enhanced with a Radianite coating. This combination achieves low friction high hardness and high corrosion resistance making overall durability and erosion from muzzle blast a non-issue. – The INTRA-LOK® mounting system uses the taper lock principle; a tapered locking screw interfaces with an angled V-groove on the underside of the barrel. This perfectly times the compensator as it locks down onto the upper barrel profile on the muzzle end of the barrel. – INTRA-LOK® allows the user to simply slide the compensator over the barrel insert and tighten the locking screw making for a simple and repeatable installation process. This system allows the user to easily remove the barrel from the slide for cleaning. – Installed onto a Sig Sauer® P365® or P365X the AFTERBURNER + RAMJET combo increases the overall length of the slide to a P365XL allowing compatibility with all P365XL holsters. – This combination kit is for: SIG SAUER® P365® & P365X (3.1 SLIDE)
