The Radian Afterburner + Ramjet for the Glock 17 Gen 6 in black and bronze (brand part no. R0989) is the compensator-and-barrel system that Radian Weapons re-engineered for the sixth-generation Glock, machined to the Gen 6 barrel geometry that differs just enough from Gen 5 to rule out cross-compatibility. The Ramjet is a ported barrel cut from hardened 416R stainless steel with a gas sealing chamber, and the Afterburner compensator mounts to it through Radian’s threadless interface rather than muzzle threads. Together they vent gas upward to hold the muzzle flat, which Radian describes as reduced recoil, better muzzle control and more consistency through long strings of fire. The black and bronze finish pairs a dark barrel with a bronze compensator for a two-tone look on a Gen 6 slide. For a Gen 6 G17 owner who shoots fast, it is the drop-in way to get a compensated gun without a threaded barrel.

Key Specifications

• The barrel is hardened 416R stainless steel, the standard material for match-grade pistol barrels.
• The compensator is hardened stainless steel, built to take the gas load at the muzzle.
• The interface is threadless, so the Afterburner indexes to the Ramjet without muzzle threads or timing shims.
• The Ramjet is a ported barrel with a gas sealing chamber, Radian’s method of feeding the compensator cleanly.
• Fitment is Glock 17 Gen 6 only; Radian machines it to Gen 6 geometry and does not rate it for Gen 5 pistols.
• The finish is black and bronze, a two-tone combination on the barrel and compensator.
• The chambering is 9mm Luger, matching the factory Glock 17 barrel.

Frequently Asked Questions

Will it fit a Glock 17 Gen 5? No. Radian builds this version to Gen 6 specifications and states that the barrel geometry differences prevent safe cross-compatibility with Gen 5 models.

Do I need a threaded barrel? No. The Ramjet barrel is threadless and the Afterburner compensator mounts to it directly, which is the point of the system.

What does the compensator do for a 9mm? It redirects gas to counter muzzle rise, which Radian describes as reduced recoil, improved muzzle control and more consistent hits during fast strings.
