Been a dream to build one from scratch. Would love to put one together similar to my Colt GAU5A I carried in the Air Force except in semi auto.
that would be a cool build, similar to the XM177 right? A2 upper with 4 pos stock and round CAR handguards? 11.5" pencil barrel with a 4.5" flash hider. With the standard furniture you could really do that one as a budget build. I see those stocks pretty regularly for about $20, you can get take-off handguards for under $10. I don't own a single retro rifle, everything I have has an A3 upper so I wouldn't mind something like this either.
