Lock in rock-solid muzzle device alignment with the TacFire AR-10 Muzzle Brake Crush Washers. Precision-formed from stainless steel for durability and corrosion resistance, these single-use crush washers simplify timing and securement of AR-10/.308 muzzle brakes, compensators, and flash hiders. Sold in a convenient 10-count pack, the MAR060SS kit is perfect for armorers, builders, and shooters who swap devices, try new setups, or maintain multiple rifles.
Why Choose TacFire Stainless Crush Washers?
Correct timing made easy: Apply proper torque to “crush” the washer and index your muzzle brake ports exactly where you want them—no shims or guesswork required.
Durable stainless steel: Resists rust and galling better than plain carbon steel, ideal for high-round-count rifles and humid or wet environments.
Consistent deformation: Reliable crush characteristics help achieve precise alignment within the correct torque window when installed per best practices.
AR-10 / .308 ready: Sized for typical 5/8x24-thread .30-cal muzzle devices used on AR-10/7.62 NATO builds (verify your barrel thread pitch).
10 per pack: Keep spares on hand for new builds, device changes, and maintenance without waiting on parts.
Compatibility: Designed for .30-caliber applications commonly using 5/8x24 muzzle threads (AR-10, .308 Win/7.62 NATO, 6.5 Creedmoor with 5/8x24, etc.). Always confirm your exact barrel thread and device specs.

When to Use a Crush Washer vs. Shims
Crush Washer: Quick, simple installs where a small rotational adjustment (usually within ~¼–¾ turn under torque) achieves perfect timing.
Shim Kit: Ultra-fine indexing for suppressor mounts or precision brakes requiring exact shoulder geometry and repeatable removal/installation.
Installation Tips (Best Practices)
Verify threads: Confirm your barrel is 5/8x24 (or your device’s spec) and the device shoulder is clean and square.
Orientation: Place the crush washer beveled (concave) side toward the muzzle device and the flat side to the barrel shoulder.
Torque & time: Hand-snug the device, then torque in small increments, “crushing” the washer until the ports index correctly. Avoid over-torqueing.
Single-use only: Replace the washer if removed—do not re-use a crushed washer.
Final check: Ensure proper bore clearance, no contact with crown, and that the device is fully seated and aligned.
Note: Always follow your muzzle device manufacturer’s torque specs. For suppressor mounts or precision comps, consider shim kits if specified by the manufacturer.

AR-10 and .308 builders finishing new uppers or re-configuring rifles

FAQs
Q: Can I reuse a crush washer?
A: No. Crush washers are single-use. Install once, and replace if you remove the muzzle device.
Q: Will these work with 6.5 Creedmoor?
A: Many 6.5 CM barrels use 5/8x24 threads like .308. If your barrel is 5/8x24 and your device is .30-cal/6.5-compatible, these washers will typically work. Always verify specs.
Q: Do I need thread locker?
A: Most muzzle devices rely on proper torque/crush. Use thread locker only if recommended by your device manufacturer.
Q: Are these for suppressor mounts?
A: Some suppressor mounts require shim kits for precise, repeatable alignment. Check your suppressor/mount manual.
