{"product_id":"cmmg-ar15-crush-washer-1-2","title":"CMMG AR15 Crush Washer 1\/2\" – AR-15 Muzzle Device Installation","description":"\u003cp\u003eThe CMMG AR15 Crush Washer is a single-use timing washer designed to properly index and secure muzzle devices on AR-15 barrels with 1\/2\"-28 threading. When installing flash hiders, compensators, or muzzle brakes, this crush washer compresses during torquing to achieve correct alignment while creating a gas-tight seal between the muzzle device and barrel shoulder.\u003c\/p\u003e\u003cp\u003eManufactured from steel, this washer is intended for one-time use and should be replaced each time a muzzle device is removed and reinstalled. Installation requires a muzzle device wrench and armorer's wrench or barrel vise. Proper torque (typically 15-20 ft-lbs, consult your muzzle device specifications) ensures the washer compresses evenly without over-stressing barrel threads.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Muzzle Device Crush Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 and rifles with 1\/2\"-28 threaded barrels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2\"-28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Requires muzzle device wrench and barrel vise or armorer's wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsage:\u003c\/strong\u003e Single-use, replace with each muzzle device installation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CMMG","offers":[{"title":"Default Title","offer_id":47934702223615,"sku":"CMMG55DA5B8","price":3.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/4872529.jpg?v=1766476992","url":"https:\/\/doublestackstore.com\/products\/cmmg-ar15-crush-washer-1-2","provider":"Double Stack Store","version":"1.0","type":"link"}
