The ZEROED 36K isn’t any .36-caliber/9mm suppressor. Being overbuilt to both pistol and rifle suppressor standards makes this the can right at home on everything from 9mm pistol-caliber carbines to large-bore rifle cartridges like 8.6 BLK or 350 Legend. Not to mention all centerfire calibers below that, like 5.56mm, 300BLK, 7.62x39mm, 6.5 Creedmoor, and more! ZEROED 36K suppressors are ,K, (compact) sized, with an overall length of just 5.5″ with the included direct-thread mount installed. If you’ve already got a suppressor or preferred QD mounting system, the ZEROED 36K is HUB compatible, allowing you to use any other HUB-pattern QD mount and muzzle-device setup you like best. For easy HUB-mount removal, the included direct-thread mounts feature 7/8″ wrench flats, and the suppressor features a 3/8″ square drive in the welded front-end cap.
