Dunno if anyone has seen this yet, but a buddy of mine sent me link to Military Gun supply advertising a 5.7 AR-15 upper that uses PS-90 mags, looks pretty cool. From the description, I'm guessing it's straight blowback. Uses a standard AR lower and ejects downward through the mag well. Check it out:

A set up like that in 22long would be kinda fun.
