Strategic Sciences MFMD 300BLK | 0" OTB

The Strategic Sciences MFMD 300BLK (0" OTB) is a direct-thread suppressor designed specifically for .300 Blackout rifles with 5/8x24 barrel threading. This model is configured as a flush-mount system requiring zero over-the-barrel (OTB) clearance, meaning it mounts directly at the barrel shoulder without extending rearward. Proper fitment depends on sufficient clearance from the barrel shoulder to any forward obstruction.

The MFMD-MD installs via direct thread using the included shims and installation tool, without the need for additional adapters. It is intended for use with .300 Blackout platforms and is designed to function as a standalone suppressor configuration.
