Description

The Radian Afterburner + Ramjet combo is built for anyone who carries a P365 or P365X and wants to dial in recoil and muzzle rise without the bulk. This isn't some gimmick pair either. You get a ported 416R stainless match-grade barrel matched with a purpose-designed micro-compensator, both finished with Radianite coating for hardness and corrosion resistance.

Recoil Reduction That Actually Works

The combo reduces felt recoil by up to 44% when shooting 115-grain ammo, which translates to noticeably flatter shooting and faster follow-up shots. The Ramjet barrel has two large side ports that work together with the Afterburner's ports to direct gas upward, killing muzzle rise where you feel it most. The compensator itself is tiny, only 0.47 inches long, yet outperforms many full-size compensators on the market. People who run this setup report that the difference shows up immediately once you start shooting rapid fire.

Installation That Won't Frustrate You

The threadless barrel design is the whole point here. You don't need a threaded barrel, which means no cutting, no headaches, and no concerns about thread pitch compatibility. The INTRA-LOK mounting system uses a tapered locking screw that interfaces with an angled V-groove on the barrel's underside, ensuring perfect timing every time you install it. Slide the compensator over the barrel, tighten the screw, and you're done. When you need to clean the barrel, you simply remove the compensator and slide the barrel out of the slide. Unlike traditional threaded compensators that can lock up with carbon buildup, the Radian's design keeps the screw protected from gas and residue, so removal is effortless even after thousands of rounds.

Size and Carry Considerations

Once installed, the combo extends your P365 slide length to P365XL proportions, which means it works with P365XL holsters and maintains a form factor that's still manageable for concealed carry. It's a practical upgrade that gives you performance without turning your compact gun into a full-size handgun.

Frequently Asked Questions

Will the Afterburner + Ramjet fit my P365XL or P365 Macro?

No, this combo is designed specifically for the P365 and P365X with 3.1" slides. It will not fit the P365XL or P365 X-Macro. When installed on a standard P365, it does extend the slide to P365XL proportions, making it compatible with P365XL holsters.

How does the INTRA-LOK system compare to threaded compensators?

The INTRA-LOK system uses a tapered locking screw instead of thread engagement, which keeps the mounting screw protected from carbon buildup and gas contamination. This means you can remove the compensator easily even after thousands of rounds, whereas threaded comps can seize from carbon and require soaking. Installation is equally straightforward on both, but the Radian design wins for long-term maintenance.

What ammo works best with the Afterburner + Ramjet?

Radian's 44% recoil reduction specification is based on 115-grain ammunition. The system will work with heavier loads like 124-grain and 147-grain, but you'll see less recoil reduction since the pressure curve changes. The barrel's gas sealing chamber is engineered to work perfectly with the compensator's ports, so this matched pair performs best together.

Can I use just the Ramjet barrel without the Afterburner compensator?

Yes, the Ramjet barrel can be used on its own with the threadless design and INTRA-LOK system. However, you'll lose the recoil reduction benefits that come from the compensator working in tandem with the ported barrel. The barrel and compensator are engineered as a matched system for optimal performance.
