GONE I have an 1/12 Colt 20" C MP marked pencile barrel mounted to a slab sided Colt upper with no forward asst. and no shell deflecter with a A1 flash hider and your choice of a set of triangle and round type hand guards. The upper has a square with a C inside of right above the port door and another inspection marks. It came to me in parts and i put it together. The front sight base was canted so the front sight base has been drilled and taped for set screws to fix the cant problem. I have since shot the upper and it works great and is no longer canted. No b/bc/ch
Looking for an M4 type 16" or 14" Upper prefer flat top but a A2 will work also.
can send pictures of the upper
