The JK HD Minimalist muzzle device in 5/8×24 is the lightest, smallest way to get quick-attach suppressor mounting on a host rifle (JK part no. JK-MD-HDM24). JK Armament makes it from heat-treated, black nitrided 17-4 stainless steel at 2.2 ounces and just 1.0 inch long. It gives secure, rapid attachment and removal of JK 155 suppressors and any other suppressor with an ASR-compatible mount, such as one of JK’s taper mounts. This 5/8×24 version is listed for .30 cal and .45 cal rifles. It is a good fit for sharing a suppressor across several guns.
