I'm looking at buying an Armalite M15A4T and I was wondering if anyone has had problems mating other manufacturers uppers to the Armalite lowers? Are they mil-spec?
The reason is that I also want a 16" upper but I don't like anything else that Armalite makes. Will probably go with a Bushmaster or ZM if I can get the cash for it.
Thanks
