Radian Afterburner Ramjet Bronze Superb Glock 19/45 Gen 6 Comp Barrel Kit

Description

The Radian Afterburner Ramjet Bronze is the two-tone version of Radian’s threadless compensator kit for Gen 6 Glocks, sold as part number R0986 under UPC 810098421669. Mechanically the Radian Afterburner Ramjet Bronze is identical to the all-black R0985: the same hardened 416R stainless RAMJET ported barrel, the same INTRA-LOK taper mount, the same AFTERBURNER micro-compensator. Only the finish changes. Here the barrel carries a bronze PVD coating and the compensator stays black, so the accent sits behind the muzzle device rather than on it.

Where the Radian Afterburner Ramjet Bronze actually shows its colour

This is worth being clear about before you spend the finish premium. On the Radian Afterburner Ramjet Bronze the colour is on the barrel, and once the barrel is inside the slide with the black Afterburner compensator clamped to the muzzle, most of that bronze PVD Ramjet barrel is hidden. What you see day to day is the chamber area through the ejection port, a band of colour where the barrel emerges ahead of the slide, and the fluting when the pistol is apart.

If you wanted a bronze muzzle device, this is the wrong part number and you want the all-black kit with a bronze comp from another maker. If you want the accent to read as a detail rather than a statement, the Radian Afterburner Ramjet Bronze does exactly that. Either way there is no performance difference between the two finishes.

How the Radian Afterburner Ramjet Bronze works

Inside the Radian Afterburner Ramjet Bronze, the Ramjet match grade barrel replaces the factory tube and carries a gas sealing chamber behind the muzzle. Rather than venting straight forward, propellant gas is routed into the compensator. The muzzle itself is not threaded, which keeps the kit usable in states that restrict threaded handgun barrels, and a loaded chamber indicator is cut into the hood. The barrel is fluted to shed weight and heat.

The black Afterburner compensator slips over that gas chamber and clamps down on a single tapered screw at 15 inch-pounds. No crush washer, no shim stack, no thread locker, no gunsmith. Radian rates the Radian Afterburner Ramjet Bronze at a 44 percent reduction in felt recoil with 115-grain ammunition. Installed on a G19, the kit brings the pistol out to Glock 17 slide length, so budget for a G17-length holster.

The honest caveats

Everything true of the black kit is true of the Radian Afterburner Ramjet Bronze. A compensator makes the pistol louder to the shooter and to the person beside you, and pushes more gas, powder and particulate back toward your face, which matters indoors and from a compressed retention position. Ported barrels and comps foul quickly, so plan on cleaning carbon out of the compensator far more often than a plain muzzle.

The Radian Afterburner Ramjet Bronze also changes slide timing, and Radian says outright that recoil spring, lubrication or ammunition may need adjusting. Light 115-grain range ammunition is the floor; anything weaker can short-stroke. If the pistol has a defensive role, run a couple hundred rounds of your actual carry load through it before trusting the setup.

Two caveats belong to the finish on the Radian Afterburner Ramjet Bronze. A coated barrel takes its wear at the hood, the lug and the locking surfaces, where it rubs steel on steel every cycle, and bronze shows that wear more visibly than black does because the contrast with bare steel underneath is greater. It is cosmetic, not structural, but a high-round-count pistol will look used sooner. And a two tone Glock 19 Gen 6 build narrows the resale pool: a black kit suits any pistol, a bronze barrel only appeals to a buyer who wants that accent.

Finally, check local law before you buy the Radian Afterburner Ramjet Bronze. The Ramjet barrel ships unthreaded and is sold as fifty-state legal, but some municipalities restrict compensated or ported handguns and several competition divisions bar them from stock classes. With no muzzle threads this is not a suppressor host either.

Who the Radian Afterburner Ramjet Bronze suits

This is the pick for a build that already has a colour theme running through the internals, or for an owner who wants the pistol to look considered when it comes apart on the bench. The performance case is identical to the black kit, so choose the Radian Afterburner Ramjet Bronze on looks and nothing else. If you would rather keep it monochrome, we stock the all-black R0985 version, and the Radian Glock 19 quick-tune guide rod is the usual companion for dialling recoil spring weight back in once the compensator changes the timing.
