1:7 is too fast a twist for .22LR. Ideally you want about 1:12 but you can get by with 1:9.
Sorry, I must've missed that.Understood, its been mentioned earlier in the thread.
I'm happy with it for what its done. Still plan to try it with my scoped 1:9
So far all these rumors people told me (word of mouth at gun shows when asking if people sold them) of key holing at 25yds have been untrue for me.
Try some Aguila SSS - they are 60gr rounds and thus able to tolerate faster twist. Slow to get to the target, but consistent.
In my experience there are better options, such as a 15-22 rifle. If you don't want a dedicated rifle, get a dedicated conversion upper, but be prepared to spend more for that than a 15-22.
Not best solution for everyone. For me, With the CMMG conversion, it's quick to go from 22LR from 223 on any of my 223 ARs Plus my dad can borrow it and use it. I have no doubt the $400 15-22 has many happy customers but like the utility of grabbing any of my existing ARs and throwing in the conversion bolt. I also like not having to use up extra space in the safe. I'm sure the 15-22 is a more accurate solution also but I have 2 other 22s that are plenty accurate.This is the best advice I have seen on the topic. The 15-22 is the way to go.
Why not just build a dedicated .22LR upper. that solves all of the accuracy issues.

I believe you can later use the conversion to build a dedicatec upper.
Dedicated upper is nice if you don't mind carrying the extra weight and/or get a custom integrally suppressed one like I did. Otherwise, the 22 conversion kit is the way to go. CMMG is the best in my opinion. I used a CMMG setup, one of their barrels and their conversion kit with a collar, for my suppressed upper build.
