Reliable AR15 22LR conversion kit.

Another +1 on Nordic/JP .22 uppers. It's the most reliable, and with .22s that means a lot. The downside is that it hasn't been available for like a year. Good luck finding one.
 
2000 rounds through my Nordic Comp upper and not one issue so far. Bulk Blazer ammo gives me around a 1" group at 100yds

Pics please. We would all like to see ANY rifle that will shoot around an inch at 100 yds with the cheapest ammo out there.

Why do people have to make outsized claims about their equipment?

"Trust me sweetie, that IS 12 inches."
 
Wax coated Blazers shot really well in my rifle. Sorry you feel the need for me to prove it to you. Next time I'm at the range I'll remember to take a picture just for you.

True that Nordic uppers have been unobtanium for 1.5 years, however they are the best available from a reliability stand point. Accuracy wise they are okay. In addition to JP, DPMS also utilizes the Nordic bolt design so take a look at them also. I believe JP is now making their Nordic style uppers in house and no longer relying on Nordic Components for manufacturing. No idea on whom is making the DPMS upper.
 
I have the AR 15/M 16 M261 conversion kit which I purchased from Sarco Inc. It may be a surplus military unit?
Anyway, it is a all steel unit and well made in my opinion. I bought it last fall for about $100 or so.
It uses a all steel 10 round magazine which fits into a standard AR 15 magazine. I forget how much the mags cost.
It is a very good unit in my opinion. Works reliably with all rimfire ammo. Installed it in my Rock River upper ( 1 in 8 twist) and with CCI standard velocity ammo ( which gave me the best results) it would put 10 shots into one hole at 50'. I don't know if the units are available now. For the money and the results I would seriously check it out.
