Get your muzzle device clocked perfectly the first time with TacFire AR-15/.223 Muzzle Brake Crush Stainless Steel Washers. Purpose-built for .223 Rem / 5.56 NATO builds using the common 1/2x28 muzzle thread, these single-use stainless steel crush washers provide predictable deformation under torque so you can time your brake, compensator, or flash hider with confidence. Sold in a convenient 10-count pack, MAR059SS is a bench essential for home builders, pro armorers, and anyone who changes muzzle devices for testing or tuning.
Why Choose TacFire Stainless Crush Washers?
Fast, accurate timing: Simply torque to index side ports or prongs exactly where you need them—no complicated shim math for typical installs.
Stainless steel durability: Resists rust, galling, and weather better than plain carbon steel—ideal for hard-use rifles and humid environments.
Consistent crush characteristics: Reliable, repeatable deformation for secure lock-up within proper torque windows when installed correctly.
AR-15 / .223 ready: Sized for 1/2x28 threads found on most 5.56/.223 barrels (verify your barrel thread pitch).
Value 10-pack: Keep multiple washers on hand for new uppers, seasonal swaps, or shop inventory.
Compatibility: Designed for .22/.223/5.56 caliber muzzle devices on barrels threaded 1/2x28. Always confirm your barrel’s thread pitch and device specifications before installation.

Crush Washer vs. Shim Kit — When to Use Which
Crush Washer (this product): Quick, straightforward installs where a small rotational range (~¼ to ¾ turn during torque) hits perfect timing on typical brakes/flash hiders.
Shim Kit: Ultra-precise indexing for suppressor mounts, certain match comps, or when manufacturers specify exact shoulder geometry and repeatable removal/installation.
Installation Guide (Best Practices)
Verify thread pitch: Confirm 1/2x28 threads and clean both shoulder and device.
Orient correctly: Install with the beveled/concave side toward the muzzle device and the flat side against the barrel shoulder.
Hand-snug, then torque: Tighten in small increments, allowing the washer to crush until the device’s ports or prongs are properly indexed. Avoid over-torqueing.
Single use only: If you remove the device, replace the crush washer—do not reuse.
Final checks: Ensure concentricity and muzzle crown clearance; verify there’s no contact with the bore path.
Note: Follow your muzzle device manufacturer’s torque specs. For suppressor QD mounts or precision comps, a shim kit may be recommended.
Ideal For
AR-15 / .223 builders finishing new uppers

Care & Tips
Keep spares in the range kit: Handy for on-site changes or corrections.
Avoid excessive lube: A lightly oiled thread is fine; excess can affect torque readings and attract fouling.
Inspect device alignment: Especially important for comps/brakes with directional ports.
FAQs
Q: Can I reuse a crush washer?
A: No. Crush washers are single-use; always install a new one after removal.
Q: Will this work on 9mm or .30-cal barrels?
A: This model targets 1/2x28 (.223/5.56). Many 9mm and .30-cal barrels use different threads (e.g., 1/2x28 for some 9mm, 5/8x24 for .30 cal). Verify thread pitch and caliber compatibility.
Q: Do I need thread locker?
A: Most muzzle devices rely on proper torque/crush. Use thread locker only if specifically recommended by your device manufacturer.
Q: Is this suitable for suppressor mounts?
A: Some suppressor systems require shim kits for exact timing and concentricity. Check your mount’s instructions.
