Product Description The LUTH-AR 308-BL06CW is a precision-engineered .308 crush washer built for AR-10 platform rifles chambered in .308 Winchester and 7.62x51mm. Featuring a 5/8-24 thread pattern and constructed from durable steel, this crush washer is an essential component when installing muzzle devices such as flash hiders and muzzle brakes. As the muzzle device is torqued down, the washer deforms to create a secure, properly timed fit without damaging the barrel or device. Compact and lightweight at just 0.10 oz, the LUTH-AR .308 crush washer is an ideal solution for new builds or replacing a worn-out washer.
