{"product_id":"grovtec-crush-washer-223-5-pack","title":"GrovTec Crush Washer .223\/5.56 – 5 Pack","description":"\u003cp\u003eGrovTec crush washers provide the proper indexing and sealing for .223\/5.56 muzzle devices. These single-use washers compress during installation to time your flash hider, muzzle brake, or compensator to the correct orientation while creating a gas-tight seal between the device and barrel shoulder. Essential for any muzzle device installation or replacement.\u003c\/p\u003e\u003cp\u003eManufactured from heat-treated steel with a phosphate finish for corrosion resistance. Each washer is designed to deform during installation—this is normal function. Once compressed, the washer cannot be reused. Installation requires an armorer's wrench and proper torque spec (typically 15-20 ft-lbs for most muzzle devices, but consult your specific device manufacturer). Five-pack ensures you have spares for multiple installations or do-overs if timing isn't perfect on first attempt.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Crush Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2x28 (.223\/5.56)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-Treated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Requires Armorer's Wrench and Torque Wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 5 Crush Washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Single-Use Only – Do Not Reuse\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GrovTec","offers":[{"title":"Default Title","offer_id":47938106523903,"sku":"GTHM319","price":15.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2864947.jpg?v=1766501630","url":"https:\/\/doublestackstore.com\/products\/grovtec-crush-washer-223-5-pack","provider":"Double Stack Store","version":"1.0","type":"link"}
