Are the pins in the upper tight by themselves or are they tight for the whole upper/lower assembly?
I take it you are using one of their flattop uppers without a forward assist? Correct?
If that is the case, another option would be to buy a Colt 750 LMG upper, remove the receiver, and sell off the rest. I know this isn't very likely but is another way to get what you want and their won't be any **** ups.
