The PS90 is one of those platforms where the details matter, and the muzzle is usually the first thing people notice on a shortened build. This CMMG flash hider is styled after the original P90 profile, so once it's installed your carbine picks up that classic bullpup silhouette instead of looking like something is missing off the end of the barrel. It's machined from steel and wears a matte black finish that blends right in with the factory hardware.
The threads here are M12x1 left-hand, which is the correct pattern for the PS90 platform and a direct match for CMMG's 10.4 inch PS90 barrel. That left-hand thread detail trips up a lot of first-time builders shopping for generic muzzle devices, so it's worth pointing out that this one is cut specifically for the job. Installation is straightforward, and the compact profile keeps the overall package tight, which is the whole point of running a shorter barrel in the first place.
Beyond the looks, this device does real work. Trimming barrel length on a 5.7x28mm gun means more unburned powder exiting the muzzle, and that translates to a bigger fireball, especially indoors or in low light. A proper flash hider knocks that signature down so you keep your sight picture between shots instead of blinking through a flash bulb. At right around three ounces, it accomplishes that without changing how the gun balances or handles.
CMMG has been a go-to name for PS90 barrels and parts for years, and this flash hider follows the same playbook: correct threads, durable steel construction, and a finish that holds up to regular range use. If you're finishing out a shortened PS90 or just want a period-correct muzzle device that fits the first time, this is the simple answer. Match it with the CMMG PS90 barrel and the whole setup comes together clean.
It's built for PS90 barrels threaded M12x1 left-hand, and it's a direct match for CMMG's 10.4 inch PS90 barrel. The standard 16 inch factory PS90 barrel doesn't come with an exposed threaded muzzle, so this device is really intended for shortened builds or aftermarket threaded barrels. Confirm your barrel's thread pattern before ordering.
The P90 platform uses M12x1 left-hand threading from the factory, so CMMG cut this flash hider to match. That means it tightens counterclockwise, which is the opposite of most AR-pattern muzzle devices. It's normal for the platform, just keep it in mind during installation so you don't fight the threads.
It's styled after the original P90 profile, so it gets you very close to that classic military silhouette. It isn't a factory FN part or an exact replica, but on the gun it's tough to tell the difference, which is why it's such a popular finishing touch on shortened PS90 builds.
It does, especially on shorter barrels. Cutting barrel length means more powder burns outside the muzzle, which produces noticeably more flash. This device redirects and breaks up that flash so you keep your sight picture in low light, all while adding only about three ounces to the gun.
