Why Choose the ATI AR-15 .223/5.56 Stainless Steel Crush Washer Pack – 5 pcs?
The ATI AR-15 .223/5.56 Stainless Steel Crush Washer Pack provides replacement mounting hardware for compatible AR-15 muzzle-device installations.
With five stainless steel crush washers included, the pack is a convenient option for new builds, muzzle-device changes or keeping spare installation hardware available for future maintenance.
Designed for AR-15 .223/5.56 Applications
These crush washers are intended for compatible AR-15 .223/5.56 muzzle configurations.
They provide a straightforward mounting solution for supported muzzle brakes, flash hiders and other threaded muzzle devices that use a crush washer.
Helps Position Muzzle Devices
A crush washer compresses as the muzzle device is tightened against the barrel shoulder.
This controlled compression helps the installer position the muzzle device correctly while maintaining tension once installation is complete.
Useful for Timed Muzzle Devices
Many muzzle devices need to be oriented in a particular position on the barrel.
A crush washer provides a simple method for achieving that final alignment on compatible threaded barrels without adding a more complicated mounting system.
Stainless Steel Construction
These washers are made from stainless steel, providing durable installation hardware for the muzzle end of the firearm.
Stainless construction also offers good resistance to corrosion during normal handling, maintenance and storage.
Five-Piece Pack
The package includes five crush washers, making it useful for owners who maintain multiple AR rifles or periodically change muzzle devices.
Keeping several on hand also means a fresh washer is available when needed for a new installation.
Practical for Builds and Maintenance
Crush washers are small components, but having the correct one available can make a muzzle-device installation much easier.
This five-pack is a useful addition to an AR parts kit, workbench or maintenance supply.
Confirm Muzzle-Device Compatibility
Barrel threads, calibers and muzzle-device mounting systems can vary.
Always confirm that a crush washer is the appropriate installation method for your particular barrel and muzzle device before use.
Always review the ATI Fitment tab before ordering.
The ATI Advantage
ATI offers individual AR-platform components and installation hardware so owners can complete builds, repairs and upgrades without sourcing miscellaneous parts separately.
The AR-15 .223/5.56 Stainless Steel Crush Washer Pack provides five durable replacement washers for compatible muzzle-device installations.
