Thanks for the replies and the input.
as far as the New Frontier lowers go you have to admit the torture test videos were pretty impressive IMO.
Combine that with the $100 price, free shipping and the lifetime warranty you have a pretty decent deal.
Considering that if a person has other Ar,s and a 9mm sidearm then it's plausible that a 9mm AR would be nice to have around.
Regarding .22's ? Meh I have plenty of those and a 9mm is lot's more bang for the buck.
I like having a carbine to match the sidearm caliber, .40, .357, .22 and now 9mm, it just happens...
I do see the merit of a Lone Wolf lower that takes Glock mags since then it would mean I would have to pick up a G19 or at the very least convert my G23...
