When you tighten a flash hider, muzzle brake, or compensator against a crush washer, the washer deforms under torque to take up the gap between the barrel shoulder and the device's rear face, allowing you to lock the muzzle accessory down solid while still orienting the ports or prongs exactly where you want them.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe \u003cstrong\u003e5\/8x24\u003c\/strong\u003e thread specification is the industry standard for \u003cstrong\u003e.308 Winchester\u003c\/strong\u003e \/ \u003cstrong\u003e7.62x51mm NATO\u003c\/strong\u003e AR-10 platforms, and is also shared by popular AR-15 chamberings such as \u003cstrong\u003e300 Blackout\u003c\/strong\u003e and \u003cstrong\u003e6.5 Creedmoor\u003c\/strong\u003e. That means a single washer covers the bulk of large-bore centerfire rifle builds using common muzzle accessories. Whether you are timing a brake on a precision AR-10, locking down a compensator on a 6.5 Creedmoor barrel, or simply replacing a worn washer on a duty rifle, this part gets the job done without the slop of a peel-washer stack or the guesswork of shimming.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eLantac USA is a recognized name in the muzzle-device and small-arms accessory market, and their crush washer is built as a straightforward, no-frills \u003cstrong\u003eAR-15 accessory\u003c\/strong\u003e intended to be a one-time-use item: the washer is crushed once to set your device's timing, and left in place under the device for the life of the build. It is the kind of consumable that belongs on every workbench alongside a proper torque wrench.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003e\u003cstrong\u003eNote on installation:\u003c\/strong\u003e tighten the muzzle device to specification, check that ports\/slots are oriented correctly, and confirm the device sits concentric to the bore.
