Looking up the bore from the breech end and comparing the rifling with that from some of my other ARs, the Colt’s looked like maybe it was a bit worn or something to me so I was curious how well it would group but at 100 yards it turned out one 5-shot and one 6-shot group measuring just under 3” each. Which is fine by me for an 11.5” with iron sights and 55gr ball. Only caveat is that the POI very high above POA.
I suspected it had probably been zeroed at 25yds or something and the results on target at 100yds bore that suspicion out. I did mess with the windage a bit at 50yards beforehand but didn’t touch the elevation as the front post is one of those night sights that can only be adjusted in 360-degree increments. I don’t intend to put a lot of rounds through this upper, as like I said, I’ve got a clone for that. But it was nice to get it out there.

Nice. There is just something about the classic carbine- the fixed carry handle and short barrel looks so right.
