hello guys...
i'm planning on getting another CMMG 5.56 upper 16'' (mid-lengh) with a 1:7 twist, but i also going to install a .22lr convertion kit (i dont want a 22lr only upper) so i have this question, what kind of accuracy i can expect from a 16'' 1:7 twist upper shooting 22lr ar 50 100 yards? will the bullet be accurate or they will get all over the place? i think the twist is way too fast compared to my savage mark II with a 1:16.
Edit: i also need to know what about barrel life? will that wear out the barrel?
