The MFMD-MD is a hearing-safe, NFA-regulated suppressor module built as a standalone muzzle device for 300BLK rifles threaded 5/8×24. Designed to mount completely flush with a 0.0" over-the-barrel requirement, it installs only when the distance from the barrel shoulder to the first obstruction is unobstructed—simple and decisive for proper fit.
The device uses a direct-thread interface paired with the included shims and torque tool for precise alignment, with no adapters or secondary mounting components required. Once installed, the MD configuration reduces flash, lowers at-ear sound pressure, and cuts rearward recoil while maintaining consistent bolt velocity. It delivers measurable suppression performance without the SD or SDX modules.
