Description
The Kimura Flash Hider from Fletcher Rifle Works is built for guys who want their muzzle device to do double duty: knock down flash on a bare barrel and still give you a solid mounting point when it's time to run a can. This particular version comes with the 90 degree shoulder, which means it's cut square rather than tapered, giving you a clean, repeatable fit against the barrel face every time you thread it on.
What the Kimura QD Flash Hider Is Made Of
Fletcher builds this one out of 17-4 PH stainless steel and heat treats it to the H900 condition, which is the same process a lot of premium suppressor mount hardware uses because it holds up to heat and carbon fouling without losing its edge. That heat treat also gives the metal a distinct warm, brassy tone rather than a flat black finish, so it stands out a bit compared to your typical bead blasted muzzle device. The .375 bore keeps it versatile across common calibers running 1/2×28 threads, and the 3/4 inch wrench flats make installation and removal simple with a standard armorer's wrench.
Fletcher Kimura 90 Degree Shoulder Fit
Fletcher offers this flash hider in two shoulder styles, a Sig taper for barrels cut with that factory taper, and this 90 degree option for barrels with a standard square shoulder. Getting the shoulder style right matters more than people think, since a mismatched shoulder can throw off your timing or leave a gap that lets carbon creep in behind the threads. If your barrel has a squared face, this is the version you want.
Suppressor Ready: Kimura Flash Hider Plan B and Cherry Bomb Compatibility
What sets the Kimura apart from a basic birdcage is its compatibility with Plan B style suppressor mounts and Q Cherry Bomb adapters. That means if you're running a can that uses the Plan B taper lock system, this flash hider can serve as your quick detach interface, letting you pull the suppressor off and shoot bare without swapping muzzle devices. It's a handy setup for anyone who splits time between suppressed range days and lighter unsuppressed range trips.

Frequently Asked Questions
Do I need a crush washer to install the Kimura QD Flash Hider?
No, this flash hider relies on its 90 degree shoulder for a square, repeatable fit against the barrel face rather than a crush washer. Just make sure your barrel shoulder matches this style before ordering, since Fletcher also offers a Sig taper version for tapered barrels.
What suppressors work with the Kimura Flash Hider?
The Kimura is built to work with Plan B style suppressor mounts and Q Cherry Bomb adapters, so any can using that taper lock system can attach directly to this flash hider. It's a solid option if you want quick detach functionality without a separate mount purchase.
What's the difference between the 90 degree and Sig taper shoulder options?
The 90 degree version has a square shoulder meant for barrels with a standard flat face, while the Sig taper version is cut to match barrels with a factory tapered shoulder, like those found on some Sig platforms. Picking the wrong one can affect how flush and consistent your fit is against the barrel.
Will the Kimura Flash Hider hold up to regular use?
It's machined from 17-4 PH stainless steel and heat treated to H900, which is a tough combination that resists heat cycling and corrosion well over time. That's the same material and treatment used across a lot of respected suppressor mount hardware, so it's built to take repeated mounting and dismounting.
