Adv Tech Ar15 223/5.56 C Wshr 5pk

The Advanced Technology AR-15 223/5.56 Crush Washer 5 Pack is a precision-engineered component specifically designed for AR-15 platforms with 1/2"-28 threaded muzzles. This five-pack allows users to outfit multiple uppers or maintain an inventory for field replacements and maintenance cycles.

Crush washers serve as critical muzzle device spacers, ensuring proper timing and alignment when installing flash hiders, muzzle brakes, or compensators on .223/5.56 rifles. Installed between the barrel's muzzle crown and the threaded muzzle device, these washers compress against the barrel shoulder, creating a tight, repeatable fit that eliminates gap tolerance and locks the muzzle device in position.

This five-pack is essential for serious AR-15 operators, gunsmiths, armorer teams, and competitive shooters who frequently reconfigure their platforms. Each crush washer is a consumable component that cannot be reliably reused once compressed during installation. Having spares on hand prevents delays when changing muzzle devices during training or range work.
