Thoughts on 22lr Cmmg 20” barrel and bolt

I have the cmmg conversion kit (bcg and mags) in a “leftover parts” AR and it’s great for practice and friends/new shooters as the manual of arms is the same, but the accuracy is only so-so. It’s an under 2” at 50yds gun, fine for plinking and practice but really only that. 1:7 twist PSA barrel, ha.

Is yours a conversion or a dedicated 22lr barrel?
