This is a high quality reproduction of the M14 Grenade Launcher attachment, designated as the M76. This grenade launcher slips over the M14 flash suppressor and locks into place on the bayonet lug. Once in place, you can now shoot rifle grenades from your M14 or M1A.
M14 Grenade Launcher
Most original M76 launchers were ordered destroyed by the US Government. Those that survived are usually in very poor condition.
This is a 100% correct reproduction with the markings, design, fit and finish being exactly like the original. Once you get one of these and start shooting inert rifle grenades, you'll be hooked!
