AR-15 5.56MM CRUSH WASHER BL-06-CW

AR-15 5.56mm Crush Washer — For 1/2x28 Muzzle Devices | Model BL-06-CW | UPC 859819007690 Time your muzzle device the right way—fast, secure, and repeatable. The AR-15 5.56mm Crush Washer (BL-06-CW) is a single-use, precision-formed washer that lets you properly index and secure 1/2x28-threaded muzzle brakes, compensators, and flash hiders on 5.56/.223 barrels. Built from hardened steel with a durable black finish, this crush washer compresses predictably as you torque, delivering a tight, square lockup against the barrel shoulder for consistent accuracy and long-term reliability. Why This Crush Washer Correct timing in minutes: Easily align ports or tines to the 12 o’clock position—no trial-and-error stacking of random spacers. Clean, square lockup: Uniform cone geometry helps seat the device true to the bore and tight to the shoulder, supporting accuracy and repeatable POI. Hardened single-use design: Engineered to deform once under torque for a secure hold that won’t back off under heat and recoil. Mil-standard compatibility: Sized for 1/2x28 muzzle threads used on AR-15 5.56/.223 barrels and most 5.56-caliber muzzle devices. Low-glare protection: Black oxide (or comparable) finish resists corrosion and blends with parked, nitrided, and anodized builds. Perfect For Muzzle brakes & comps that require precise top-dead-center indexing Flash hiders (A2, 3-prong, birdcage styles) on 5.56/.223 barrels Duty, defense, and training carbines needing reliable, maintenance-friendly assembly Quick Install Guide (Best Practices) Verify fit: Confirm a 1/2x28 threaded muzzle and 5.56/.223 device. Orient the washer: Place the flat side toward the barrel shoulder and the beveled/convex side toward the muzzle device. Hand start: Thread the device on by hand with the crush washer in place until it seats lightly. Torque & time: Using an armorer’s wrench, torque to the device manufacturer’s spec (commonly 15–20 ft-lb) while rotating to final index at 12 o’clock. Do not reuse: If removed, replace with a new crush washer before reinstallation. Pro Tip: Running a suppressor or precision suppressor mount? Use precision shims or a shoulder-squaring device per the mount manufacturer—do not use a crush washer on suppressor-ready systems unless explicitly specified. Compatibility Notes Threads: 1/2x28 TPI (standard for AR-15 5.56/.223). Caliber: .223 Rem / 5.56 NATO (and other .22-cal AR-15 variants using 1/2x28). Not for: 7.62/.30-cal devices (typically 5/8x24), direct suppressor mounting, or re-use after removal. What Sets It Apart Consistent crush range supports predictable timing without over-torque. Bore-safe geometry helps keep devices square, reducing the chance of uneven gas escape that can induce POI shift. Armorers’ staple: A simple, proven solution for most 5.56 muzzle devices.
