Most of my stock AR's seem to want to shoot pretty well, and about as mentioned above, 2" or so from prone at 100 yards with GI or run of the mill reloads that approximate them.
This was shot with my generic reloads 55 gr. Hornady BTFMJ's over 748 running around 2700 fps, at 100 yards, off a rest zeroing the gun. Sight was a 4moa Aimpoint. The badge on the hat is about 1"x 1.5".

One of the two here with a red dot mounted was the gun, I just don't remember which one. Not that it really matters, as they all seem to shoot about the same. All 10.5" PSA builds.

I shot this at 100 yards, prone from a bipod with my reloads, 55 grain Nosler BT's over 4895 at 3000 fps.

This is the gun, an Armalite M15A4T 16" SS barrel FF handguard.
