TacFire AR-10 Crush Washers — Stainless Steel, 10-Pack | For .308/7.62 Muzzle Devices (SKU MAR060SS | UPC 811261022133)

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)

1. Verify threads: Confirm your barrel is 5/8x24 (or your device’s spec) and the device shoulder is clean and square.

2. Orientation: Place the crush washer beveled (concave) side toward the muzzle device and the flat side to the barrel shoulder.

3. Torque & time: Hand-snug the device, then torque in small increments, “crushing” the washer until the ports index correctly. Avoid over-torqueing.

4. Single-use only: Replace the washer if removed—do not re-use a crushed washer.

5. 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.
