Description
The Radian Afterburner + Ramjet is built for folks who want serious recoil control without adding weight or complexity to their carry gun. This combo pairs a ported match-grade barrel with a micro-compensator, engineered to work together for better muzzle control and faster follow-up shots.
Built for a Carry Gun That Shoots Better
The Ramjet barrel is machined from hardened 416R stainless steel with gas ports that work with the Afterburner compensator to cut recoil. Both components get a Radianite coating, which resists erosion from muzzle blast and reduces friction across the board. The result is a system that handles rounds reliably while staying corrosion-resistant and durable enough for regular use.
Installation Without the Headache
What makes this setup different from typical threaded barrel compensator setups is the INTRA-LOK mounting system. Instead of threads, you slide the compensator onto the barrel, insert a tapered locking screw into a V-groove, and tighten it down. No thread locker needed, no permanent commitment. You can swap it back to the original barrel for cleaning or storage in minutes. The whole process is repeatable, so you get consistent timing every time you reinstall it.
Staying in Profile for Your Holster
Once installed on your P365XL, this combo maintains the XL slide length, so all your P365XL holsters stay compatible. You're getting measurable recoil reduction without changing the footprint that made you choose that gun in the first place.

Frequently Asked Questions
Is this combo truly tool-free to install?
Mostly. You'll use the included TORX bit to tighten the locking screw, but that's the only tool needed. No thread locker, no specialized equipment. Just slide the compensator onto the barrel, insert the screw into the V-groove, and tighten. The whole process takes a few minutes.
Can I swap back to my original barrel easily?
Yes. The threadless INTRA-LOK system is designed for quick changes. Remove the locking screw, slide the compensator off, and your original barrel goes back in. You can do this at home without any gunsmith work.
Will this fit my existing P365XL holsters?
Yes. The Afterburner + Ramjet maintains the P365XL slide length, so all your P365XL-compatible holsters will work. The combo is specifically timed and designed to keep the same footprint.
What kind of recoil reduction should I expect?
Testing shows up to 44% reduction in recoil with standard 115-grain ammunition. Real-world results depend on your grip, stance, and ammunition, but users consistently report noticeably flatter shooting and better control for follow-up shots compared to a standard barrel.
