FULLY TRANSFERABLE FLEMING FIREARMS REGISTERED RECEIVER HK-51 A3 MACHINE GUN
03-2064 | Cal. 308. | S# A047787. | Bbl. 8.9″.
The HK-51 is the fire-breathing, decibel-increasing, earth-shaking older brother that the MP5 never wanted in the first place. At first glance the HK-51 appears to be an 9mm MP5 SMG, w/ something just a little off. Proportionately everything is the same. The fat triangular handguard & the meat tenderizer A3, collapsible buttstock looks correct but subtle differences such as the placement of two pins at the rear of the trigger group & a mag. well that just doesn’t look right. Even though the HK-51 delivers a thunderous amount of energy, the up-scaled roller locking mechanism, similar to that used in the G3, tame this beast, if only for the shooter. Protected post front sight & drum style, four position rear sight. FABIAN BROS. / DTA MIL BRAKE in place of traditional flash hider. Smooth side 0-1-20 faux pinned/clip-on trigger group.
