The Ramjet and Afterburner combo brings real performance gains to the Glock 48 platform without the complications of threaded barrels. Built from hardened 416R stainless steel with a durable Radianite finish, both components are engineered to handle sustained shooting without wear or corrosion issues that plague other systems.
The fluted Ramjet barrel is match-grade quality, delivering tighter groups than factory Glock barrels while keeping the gun manageable for carry. The barrel features precision porting that works in tandem with the compensator—run it solo and you miss half the benefit. Radian designed these parts to speak the same language, with the compensator's ports perfectly aligned to redirect gas upward and control muzzle flip.
At just 0.47 inches long, the Afterburner delivers performance you'd expect from full-size comps while keeping your G48 slim enough for appendix or IWB carry. The angled front faces actually help with holstering instead of catching fabric. Radian claims up to 44% recoil reduction with 115-grain ammo, and that translates to noticeably faster follow-up shots and better control during rapid fire. Real shooters report the difference matters on the clock.
Instead of threads, Radian's INTRA-LOK system uses a tapered locking screw that engages a V-groove on the barrel underside. Slide the comp on, insert the screw, tighten it to spec, and you're done. No crush washers, no indexing, no permanent modifications. When it's time to clean, the compensator comes off the same way it went on, and carbon buildup won't lock things together like threaded designs often do. The system stays reliable and repeatable, run after run.
Radian engineered this for 124-grain and heavier ammunition where the gas pressure curve feeds the ports properly. Lighter rounds work but produce less recoil reduction. Expect a short break-in period—around 100 to 200 rounds—before everything settles. Most shooters see minor reliability quirks disappear after that. The threadless design means the slide length increases by roughly half an inch, keeping you compatible with most standard Glock 48 holsters.
No. The Afterburner is so compact that standard factory Glock sights clear it without issue. The compensator height doesn't interfere with your optics or irons, so you can keep whatever sights you're running now.
Radian designed the system around 124-grain and heavier loads, which produce the right gas pressure curve to feed the ports correctly. You'll see the advertised 44% recoil reduction with that weight range. Lighter ammo still cycles fine but produces less comp effect.
It's genuinely simple. Loosen the tapered screw with an appropriate tool, tap it gently with a soft hammer if needed, and the Afterburner slides off. The screw sits away from carbon buildup thanks to the design, so you won't have to soak anything in solvent to get it apart like you might with threaded comps.
It'll fit most G48 holsters since the combo only adds about half an inch to slide length. If your holster is fitted very tightly, you may want to verify fit before relying on it for daily carry. Kydex and polymer holsters typically have enough room.
