I've been issued both Colt and FN M4s, and there's no practical difference between them functionally or in terms of accuracy. Would be proud to own either.
Issued by whom?
Is FN now making M4's? I know Colt lost the DOD contract but it was contested, never heard who wound up with it.
Issued by the U.S. Army, units I've been assigned to have had both manufactures.
Of interest, a past rifle I was issued had been refurbed up to M16A1 standards ( I've been around a while) it had a 4 digit serial, and was stamped "Colt XM-15" on the receiver. It also had 4 rebuild stamps on it, and this was in 1991. You just don't see that any more, since there have been so many new weapons made and pumped into the system due to wear and tear in theatre.
