The Strategic Sciences MFMD .338 4.0″ OTB (Over-The-Barrel) Muzzle Device is designed for .338 Lapua Magnum rifle platforms with 3/4×24 thread patterns. This direct-thread muzzle device is intended for use with compatible suppressor systems and requires sufficient over-the-barrel clearance for proper installation.
This model installs directly to the barrel using the included shims and installation tool, eliminating the need for additional adapters. The 4.0″ over-the-barrel design requires clearance from the barrel shoulder to the first obstruction, making proper measurement important for compatibility. Available in Black or FDE finishes, this muzzle device is intended for use with compatible .338 caliber rifle setups.
