bull barrels are easy to install on 10/22s usually they are oversized so you just take some sandpaper if needed and they fit in snug. Also I think with that kit you can't use a 16.5" barrel because it'll be an SBR* (not positive) I think a 18" would do fine. I have used TacSol and Volquartsen barrels I also like Green Mt.
Wish my lady had a screen name like that.
