Radian's Threadless Afterburner Now Fits the Glock 17 Gen 6
Radian Weapons now sells an Afterburner + Ramjet compensator and barrel system for the Glock 17 Gen 6. The threadless kit launched first for the G19 and G45, and the G17 version is now official. Gen 6 owners who wanted a compensated barrel without threads have waited while Radian worked through other Glock models. The G17 kit comes in black, grey, and bronze. Radian machined it to Gen 6 specifications, so it does not swap onto a Gen 5 pistol. If you run both generations, keep the parts separated. Product details live at radianweapons.com.
Key Details
The system breaks into two parts, and each one carries specific materials and a shared finish:
- AFTERBURNER compensator: hardened stainless steel
- RAMJET barrel: hardened 416R stainless steel
- Coating: Radianite on both parts, for low friction and corrosion resistance
- Barrel design: gas-sealing chamber, aimed at recoil reduction and match-grade accuracy
- Installation: threadless, so you install and remove it without a thread protector or timing concerns, which simplifies cleaning
- Slide length impact: adds only 0.47 inch to the overall slide length on a Glock 17
- Holster fit: Radian states compatibility with all G34 holsters, so most owners should not need a new holster
- Colorways: black, grey, and bronze
- Legal status: Radian describes the system as legal for sale in all 50 states
Radian positions the threadless design against a typical threaded compensator. The company's pitch centers on fast removal for maintenance and a short package that stays close to stock Gen 6 dimensions. Those claims come from the manufacturer. No independent accuracy or recoil data has surfaced yet.
Background
Glock's Gen 6 pistols brought barrel and slide geometry changes that Gen 5 parts do not match. That reality explains Radian's delay. Each Glock generation needs its own barrel and compensator fit, because a few thousandths of an inch in the chamber, locking lugs, or muzzle geometry can change how a compensator seats and how the barrel locks up. A part that looks identical on a parts table can fail to time correctly or create a headspace problem in a pistol that behaves differently under fire.
Threaded barrels remain the traditional route for adding a compensator or suppressor to a Glock. The threaded barrel requires a thread protector when no device is installed, and owners often swap protectors or devices during range sessions. Radian's threadless approach removes that step. Radian launched its Afterburner line as a compensator family before expanding to specific Glock models, and the Ramjet barrel brings the two parts together into one package. The G19 and G45 versions came first, which gave Radian a production base before it tackled the G17 Gen 6 fit. The G17 version now joins that lineup.
Why It Matters for Gun Owners
If you carry a G17 Gen 6 and want a compensated setup, this kit gives you a legitimate option without a threaded barrel. The 0.47-inch length increase matters most to concealed carriers. A slightly longer slide can change how a pistol sits in a belt holster and how much clearance you need under a cover garment. Radian says G34 holsters fit, which is a good sign for owners who already own an extended-slide holster. Test the fit before you carry it. Check the slide and holster together, and dry-fire from the holster to confirm the retention and reholstering feel right.
Gen 5 owners need to pay attention to part numbers. The kit is machined for Gen 6, and Radian says it is not a substitute for a Gen 5 setup. Mixing parts can create a mismatch that affects reliability or safety, so label your barrels and compensators clearly if you keep both generations in one safe. Also check your state before you buy. Radian says the product is legal in all 50 states, but several states regulate muzzle devices, threaded barrels, and handgun rosters differently. California and New York are the states where owners should verify compliance with the exact model and configuration before purchase, and the Gen 6 model may not appear on every state roster.
DownRange Analysis
A compensator on a handgun falls outside the core Bruen question. Bruen asks whether a regulation fits the nation's historical tradition of firearm regulation when the Second Amendment covers conduct. A muzzle device on a pistol already sits within the protected right to keep and bear that pistol. The real legal fight over accessories happens in state statutes, feature lists, and NFA-adjacent definitions, not in the constitutional text. Radian's legal-in-all-50 claim stands on the design as described. It still requires you to verify your state's rules on the exact configuration.
The market signal matters more. Radian is building model-specific parts for each Glock generation rather than offering a universal fit. That tells you aftermarket makers now treat Gen 6 as a distinct platform. Expect more Gen 6 accessories to follow the same pattern, and expect buyers to pay for exact fitment. Do not assume a Gen 5 part will work on a Gen 6 pistol because the outside looks the same.
What should you do now? Confirm the part number matches your pistol generation before you order. Verify your state's muzzle device and roster rules. Check your holster fit with the slide installed. Then wait for independent accuracy and reliability testing before you rely on the match-grade claim for competition or defensive use. The product looks promising, but the performance story still belongs to the range, not the press release.
