    Sweet! We have one upper in 5.7 at the shop I work at part time, very tempting but there are a few other expensive shooters I would like to have first.

    I like that it uses FN P90 mags, that's just dang cool right there. I'd like a P-90 but at $1500 it doesn't look like it'll happen anytime soon but if the uppers are reasonably priced I could build up a AR lower then add the upper and have the best of both worlds.

    I've got two of the AR57 prototype uppers sitting on the work bench that I've gotta complete at some point (one for myself, the other for my buddy). Any chance I could get pics of the mag retention and charging handle? Thanks in advance

    I have the same upper. Really fun to shoot, and kinda cool that it ejects the spent rounds through the mag well straight down. The only issue I had was no mention was made in the instructions that you need the short buffer tube and not the longer one. I got the upper when they first came out, to go along with my fiveSeven.
