I'm disappointed that after the 11 page AR15 or AK47? thread, this is the list that has popped out. I haven't even heard of some of the brands listed, and they weren't among the suggestions from the membership in that thread. Several members already warned you away from the American Tactical Imports model (which you previously had linked to in .300 Blackout, a very expensive cartridge).
At least the Colt and the S&W surfaced in the previous thread as possible recommendations, and though I echo Jay and F2S' advice above, if forced to choose from this list I'd pick the Smith.
And please seek training on how to use whatever you purchase.
