M4/CQBR Clone, too soon to be retro?
So I picked up a Colt lower cheap and you know how new lowers are, they suddenly sprout into builds. I can appreciate the attention to detail serious "clone" builders can bring to the table. Care to answer a few questions? My plan is to build the Colt lower as an early M4 config with CAR plastic stock. Since the 10.5" CQBR upper would be bolted on... would the M4 lower be correct without the CQD sling mount? Would an A1 grip work, or am I stuck with the A2 grip? Did all CQBR uppers have the KAC NT4? Keep in mind we are talking about a converted M4 and not a dedicated Mk18. Thanks guys, this should be a fun thread!
