These single-use washers compress during installation to create proper torque and position for flash hiders, compensators, and muzzle brakes without requiring shims or excessive force. The stainless steel construction resists corrosion and maintains integrity under the heat and pressure of repeated firing.\u003c\/p\u003e\u003cp\u003eInstall one washer between the barrel shoulder and muzzle device, then torque to manufacturer specifications. The washer deforms to lock the device in place with proper alignment. Each washer is designed for one-time use; replacement is required when removing or re-timing muzzle devices. Five-pack provides spares for multiple installations or adjustments. Compatible with standard 1\/2x28 threaded AR-15 barrels chambered in .223 Remington or 5.56 NATO.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Crush Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e .223\/5.56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2x28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 5-Pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 platform rifles\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATI Outdoors","offers":[{"title":"Default Title","offer_id":47943506952447,"sku":"ADVA5102254","price":12.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1240109.jpg?v=1766580890","url":"https:\/\/doublestackstore.com\/products\/adv-tech-ar15-223-5-56-c-wshr-5pk-ss","provider":"Double Stack Store","version":"1.0","type":"link"}
