Strike Industries took the cult-favorite Type 89 muzzle device and reworked it into the JComp Gen2. The result is a compact steel compensator that keeps the sight picture flat during rapid strings so your follow-up shots land where you want them. The two-chamber design does double duty as a hybrid brake and comp, cutting muzzle rise and taking a real bite out of felt recoil. Range feedback backs it up, with plenty of folks noting a noticeable drop in kick right out of the gate on both .223 and 5.56.
The original JComp earned its reputation, and Strike leaned on real user feedback to sharpen the Gen2. The favorite traits carried over, but muzzle rise compensation got a serious upgrade. The design traces back to the Type 89 rifle fielded by the Japan Self-Defense Forces and specialized Japanese units, which is where that distinctive ported look comes from. It is machined from steel with a black finish, so it holds up to heat and hard use without a lot of fuss.
Threads are cut in 1/2×28, the standard pitch for .223/5.56 AR barrels, and the body comes pre-drilled for pinning and welding if you want to run it on a shorter barrel setup. At 2.55 inches long and roughly 3.6 ounces, it stays light and compact on the end of your muzzle. Install is straightforward, and most people get it timed with a standard crush washer and an adjustable wrench.
One of the smarter touches on the Gen2 is compatibility with the Strike Industries Oppressor and Ferfrans concussion reduction devices. That means you can start with the bare comp for the best control, then add a blast mitigator down the line if the concussion at the bench gets to be too much. It is a flexible setup for competition, practical shooting, or varmint work where quick, repeatable follow-ups matter.
It is a hybrid, which is what makes it so useful. The two-chamber design compensates for muzzle rise to keep your sights flat while also braking to soften felt recoil. You get the best of both worlds in one compact steel device.
If your barrel has the standard 1/2×28 thread pitch, you are good to go, and that covers the vast majority of .223/5.56 AR-15 barrels. Install is simple with the included crush washer and an adjustable wrench to time it. The body is also pre-drilled for pinning and welding if you plan to run it on a shorter barrel.
Yes, and that is one of the upgrades over the original. The Gen2 is built to work with the Strike Industries Oppressor and Ferfrans concussion reduction devices. You can run the bare comp for maximum control, then bolt on a mitigator later if the concussion at the bench becomes an issue.
It does. Shooters consistently report a noticeable reduction in felt recoil and muzzle climb, with some saying it cuts the kick significantly on both .223 and 5.56. Keep in mind that effective comps like this one do redirect gas outward, so expect it to be louder to the sides than a bare muzzle.
