Todays halfway failed project…..
I really wanted to take my colt gen 1 LMG apart and put the prototype flattop upper on it as used on the USMC trials but unfortunately do not have the tools to take the upper apart so this works for now.
The lower on this is a real deal demilled M16AR prototype magwell serial XMC000000 and the pivot pin and mag catch are original to the lower.
The upper is a legit spare prototype upper that I wanted to use to put this all back to 100%. I snagged it years ago not knowing what it was and lucked into this listing shortly after I snagged the magwell. So it all came together perfectly!
Both rifles have slickside open bolt BCG, bolt catches and hydraulic buffers with green springs as well as diemaco marked grips. The other gen 2 upper has a prototype lancer mag used in the lmg trials and a Troy northern guard lower that was meant for the Canadian guard before the ban hit.
I truly want another barrel assembly to put on the flattop to I can keep the other one original and also need an m60 bipod but this works for now.
The listing posted ended last year and had serial #1 and the other picture is of the lmg green springs vs a normal rifle length spring
