.22lr accuracy in 1/9 or 1/7 barrels?

I was looking at the M1S dedicated .22lr upper do you have any pics

I am sorry, as I do not have that ability at this time. There is nothing special in appearance. It has a flattop upper, standard (now old style small diameter) handguards, fixed front sight base and 10.5 inch heavy barrel. This closely matches my Mk18 Colt upper.

Another 200 rounds of Federal 'bulk pack' through it today - no issues.

I'm glad you asked as I was about to start the same thread. I've not benched mine yet but have had good results with a 1/9. Haven't tried a 1/7 yet. But the 1/9 at 25-30yds is pretty tight.

I was watching a vid online of a guy using a CMMG kit in his Rock River. He was hitting an 8" plate at 160yrds. Looks like a fun little kit to have.

I have to revise mine a little after shooting a couple of different brands I end up with softball maybe baseball size groups at 50 yards. I still need to test different types of ammo I haven't tried any CCI yet. I actually think the Winchester super X round nose 1300fps brand I got didn't hold groups too well. I didn't do any scientific measurements though. The Federal (Walmart) bulk pack seemed to do ok. I will let you know if my findings on the CCI stand out.
