You have a feeling eh, case closed then, don't get one, I for one will get one, and since I read enough reviews I know the S&W is a way better deal than the Colt. I guess only time will tell who's right.
The GENERAL consensus is that the M&P 15-22 is a MUCH BETTER rifle than the Colt. Google is your friend.
I was in the Washington state recently and got to handle both firearms.....M&P15-22 is the hands down winner.

Is the bushmaster carbon 15 non-res?
A .22 that looks like a AR is restricted but a Tavor, SKS, M14S, AR180B, XCR, CZ, etc is non-restricted...Tell me why I hate the CFC again
..... The M&P15/22 is under $600 including shipping..... Thats a differance of 10,500rnds of .22!![]()
