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. Key Features & Benefits Material: Stainless steel for corrosion resistance and long service life Function: Single-use crush washer for timing and securing muzzle devices Use Cases: Align ports/vents on brakes and comps; set prongs on flash hiders at the correct clock position Finish: Natural stainless—pairs cleanly with black nitride, parkerized, and bead-blast finishes Quantity: 10 per pack Brand / SKU: TacFire MAR059SS UPC: 811261022119 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 Tinkerers & testers swapping brakes/flash hiders for recoil or flash comparisons Shops & armorers who need a reliable stock of single-use timing washers Specifications (Quick Reference) Platform: AR-15 / .223 / 5.56 NATO Thread Fit: 1/2x28 muzzle devices (verify) Caliber Class: .22 / .223 / 5.56 Material: Stainless steel Package Count: 10 washers Model/SKU: MAR059SS UPC: 811261022119 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.
