COLT LMG R0705 UPPER, 

Up for sale is a very nice and hard to find complete Colt heavy barry open bolt LMG upper R0705. The sale includes all of the original open bolt parts, open bolt BCG, hydraulic buffer, buffer spring, open bolt trigger parts(M16 lower not included). This was designed to run as a squad automatic weapon (SAW)using bata Mags and will convert your registered M16 to fire from the open bolt position which helps prevent cookoff and lets air circulate while not being fired. This will only be sold/shipped were legal and an FFL and or proof of registered M16 type machine gun registration will be required. 

The Colt LMG is the smoothest and most controllable rifle-caliber machine gun I have ever fired.

LOWER RECEIVER NOT INCLUDED,
