At 1.55 inches in diameter and 2.10 oz. the HD provides a properly sized mounting footprint for compatible JK Armament suppressors while contributing minimal weight to the overall suppressed system configuration. The 5/8x24 thread pitch provides broad compatibility across .308 Win 7.62 NATO and other common centerfire rifle-caliber hosts that utilize this standard muzzle thread making the HD a versatile thread mount solution across the most widely used large-bore centerfire rifle platforms. For any JK Armament suppressor owner running a 5/8x24-threaded rifle host the HD delivers a purpose-built stainless steel thread mount finished in black Cerakote and built to JK Armament s exacting standards.
