Product Info for Stern Defense SD FH45 MOD1 Muzzle Device

New AISI 4140 heading straightened .45 caliber muzzle devices such as the Stern Defense SD FH45 MOD1 Muzzle Device are designed to direct muzzle blast forward and away from the shooter rather than up and down. This muzzle device by Stern Defense eliminates the need for a flash hider and converts any .45 caliber muzzle into a full auto functioning threaded .45 caliber muzzle first stage flash hider. The helical right handed 1:6 twist design on the Stern Defense SD FH45 MOD1 Manufactured Flash Eliminator keeps the flash hider tight under even the most strenuous situations and ensures powder burn eliminating flash signature.
