M203 LMT 37MM Launcher Barrel Mount originally designed to on a M16 AR-15

M203 LMT 37MM Launcher Barrel Mount originally designed to mount on a M16 or AR-15 This unit uses the same receiver/frame as the M203 grenade launcher but is fitted with a 37mm smooth bore barrel for 37mm flares. The mounting kit with handguard for full size M16/AR-15 or M4 can be purchased directly from LMT or on Gun Broker You would need an NFA tax stamp and application if you wanted to replace the barrel with a 40mm tube. This 37mm M203 installs and operates just like its 40mm USGI big brother. Simply release the top locking lever, slide the tube forward, drop in the round, snap the tube back, and you’re ready to light up the night or lay down a smoke screen. LMT’s M203 attaches to either a standard M16A2 rifle barrels with a .625" front O.D. or an M4 carbine barrel with the grenade launcher cutout in front of the gas block, with a GI-type barrel nut at the rear. The M203 37mm Launcher from LMT! is exact the same as 40mm grenade launchers used by the U.S. Army since 1969 except in a 37mm smoth bore. LMT’s M203 launches 37mm flare, smoke, or rubber ball rounds, making it completely legal for civilians to own, with NO FFL required. (The smaller caliber completely prevents the loading of military 40mm ordnance in this launcher.)
