The LBE Unlimited ARCW308 Black 17-4 Stainless Steel Crush Washer is a precision muzzle device mounting component built for .308 AR-10 rifles. If you're installing a suppressor, muzzle brake, or flash hider on your AR-10, a quality crush washer belongs in your build. This one handles the critical job of properly spacing your muzzle device on the barrel while distributing load evenly—something that matters for both accuracy and longevity. LBE Unlimited's crush washer is manufactured from 17-4 stainless steel and finished in black, giving you a component that won't corrode and blends seamlessly with modern AR-10 setups.
Crush washers are consumables by design: they crush and deform during installation to create a barrier and stabilize your muzzle device. Unlike solid shims, a proper crush washer absorbs installation stress and helps ensure your suppressor or brake stays put under firing loads. The 17-4 stainless material means it'll hold up across seasons and climates without rust or pitting—important for precision rifles where consistency counts. Whether you're building a long-range hunting AR-10, a match gun, or a tactical platform, this washer gives you a proven solution from a brand known for no-nonsense AR parts.
Installation is straightforward: thread it onto the barrel ahead of your muzzle device, then tighten as you normally would. The washer will crush and conform to the barrel shoulder, taking up space and centering your brake or suppressor. It's a small part with an outsized role in the stability and performance of your setup. Keep a spare or two on hand—if you're swapping devices frequently or experimenting with configurations, you'll appreciate having backups.

| Caliber/Application | .308 / AR-10 |
| Material | 17-4 Stainless Steel |
| Finish | Black |
| Type | Crush Washer / Mounting Accessory |
The ARCW308 is designed for .308 AR-10 barrels. Confirm your barrel's thread pattern and diameter before purchasing—AR-10s can vary. This washer is caliber and platform-specific.
A crush washer is a spacer and stabilizer that helps center your muzzle device on the barrel and absorbs installation stress. It's a standard part of proper muzzle device installation and highly recommended for both suppressors and brakes.
This washer is designed for AR-10 threaded barrels chambered in .308. If your platform or barrel uses a different thread pitch or configuration, you'll need to verify compatibility—do not assume it will fit other .308 rifles.
Crush washers are designed to deform and crush during installation. Once crushed, they typically cannot be reliably reused. Keep spares on hand if you plan to swap muzzle devices frequently.
