    Default AR-57 Uppers in 5.7!!

    Check it out. Seems like a fairly cool idea if they will function correctly.

    Really cool until you have to buy ammo for it. Ouch.

    I guess I don't get it. If I wanted a PS90, I'd buy a PS90.

    What you get with a AR upper is a hybrid that lacks most of the advantages of the PS90 in terms of compactness. So you end up with something the same length as an M4 but with a less effective cartridge.
