A QD mount screws into the back of a modular suppressor and lets it lock onto a matching muzzle device. The muzzle device stays on the rifle; the suppressor and mount come off together. You need both halves: this mount and a muzzle device that presents the same interface.
This one locks onto any Plan-B muzzle device and threads into suppressors with a HUB 1.375x24 rear.

Which ones fit your barrel and host?
See all 796 in the Builder- Per Big Hoss's spec sheet, with any Big Hoss muzzle device this mount puts the suppressor's rear face 0.175" in front of the barrel shoulder. That is how much length the mount and device add, whichever Big Hoss device you use.
- Takes any muzzle device built to the open Plan B (0.90x24) standard and presents 1.375x24 HUB threads (0.35" long) to the suppressor.
- Machined from 17-4 stainless steel heat treated to H900, finished in nitride.
- Big Hoss recommends cleaning and degreasing the threads, then installing with 2 to 4 drops of Rocksett, torqued to 35 to 45 ft-lbs, using timing shims rather than a crush washer.
