Anyone who has spent time on the bench knows a crush washer is one of those small parts that makes or breaks a clean muzzle install. Strike Industries built this .308 pack to do exactly what it's supposed to: seat solid against the shoulder, crush evenly, and let you time your brake or flash hider where you want it. These are made to military-spec standards and sized for AR-10 and .308/7.62 platforms, so the fit is right the first time.
These are steel with the hardness dialed in on purpose. Too soft and they mush before your device clocks straight; too hard and they fight you the whole way. Strike Industries found the middle ground, which is why installation goes smoothly whether you're mounting a device fresh or swapping one back on after a cleaning. The matte black finish keeps things low-key and blends in with most muzzle brakes, compensators, and flash hiders instead of standing out.
Crush washers are a one-and-done part. Every time you pull a muzzle device, you want a fresh washer going back on to get a proper crush and a repeatable seal. That's the whole reason the 10-pack makes sense. Whether you build a lot of rifles, run an armorer's bench, or just like keeping spares in the parts bin, having ten on hand means you're never halfway through a job and out of luck. It's a smart pickup for anyone who tinkers regularly.
These are designed specifically for .308 and 7.62 threaded barrels, so match them to that platform rather than a 5.56 gun. If your muzzle device needs a lot of extra rotation to time, some builders reach for shims or a double washer instead, but for standard installs these get the job done cleanly. Torque to spec, crush evenly, and you're set.
It seats between your barrel shoulder and muzzle device, crushing as you tighten to lock the device in place and let you time it straight. A fresh washer gives you a proper crush and a secure fit. It's a required part any time you install or reinstall a brake or flash hider.
No, these are sized for .308 and 7.62x51mm barrels and AR-10 style platforms. Strike Industries makes a separate crush washer for .223/5.56 builds. Match the washer to your caliber so the fit is correct.
Crush washers are meant for one-time use. Once crushed, the washer has deformed to seat that specific device, so pulling it and putting the same one back won't give you a reliable crush. That's exactly why a 10-pack is handy, since you can drop in a fresh one each time.
Most standard installs time up fine with a single crush washer. If your device needs a lot of extra rotation to clock straight, builders sometimes switch to a peel shim set or a double crush washer for finer adjustment. For typical brakes and flash hiders, one of these washers gets you where you need to be.
