Advise/Question 22-LR upper

[Whelenon]

If you don't go with an upper. Don't go with a conversion kit for a standard 5.56 AR. The conversion kits work great. But, the rifling in a 5.56 aren't appropriate for stabalizing a .22LR.

By the way. I like the CMMG magazines the best.

I agree, go with a complete 22LR upper. Bullet dia. is different 5.56(.223), 22LR(.222) and recommended twist rate are very differnet 5.56(1-7 to 1-9 typically), 22LR(1-16).
