I tried out some left over MK262 ammo today. Maybe I wasn't shooting my best today with the URGI, but it didn't group as good as I thought it would.
I'm always disappointed when an upper won't shoot well with mk262 (Black Hills or CBC Magtech/clone). How many rounds do you have down the tube? I usually shoot 100-to-150 rounds of miscellaneous ball (193, etc.) through any barrel before trying mk262. I've had a number of barrels where accuracy improved markedly once they were 'coppered-up' a bit. YMMV.

Probably have 105-110rds fired. I have to buy some more, but I'll try it again later.
Also, someone asked (on TOS) about ejection patterns. I used the supplied Super 42 spring, but changed to H2 buffer. It didn't seem to change the ejection pattern, but what I noticed was:
M193 and MK262- 4 o'clock ejection
M855- 2 o'clock position
I wouldn't be disappointed shooting 3moa with a 2moa dot without mag. that's pretty good imho.
Surely with a nice 4 or 6 power optic those 3moa groups turn into sub moa with some concentration and the right load.
FWIW, the stripped, complete, and Colt clone correct versions are all 10% off (use code NDX) with free shipping here.
The Colt clone correct ones are pre-order only but the code still applies. If the code isn't working (some have reported this) then just enter it on the last page of checkout where the payment info is and it should work. It's good for another 3-5 hours
