    There is one at a local GS that is hanging on the wall all by itself, and I'm tempted to buy it, but I'm wondering why it is still there when everything else has been gone for weeks.

    Probably because it was around $1500 before prices went crazy and they take proprietary Sig magazines. They're good guns though.

    The Sig 550 series is not permitted in my state CT, per CT general statute 53-202a ( the Connecticut assault weapon ban ) .
    Otherwise, I would have one.
    Get it. Thou shall not regret.

    Early models had QC problems and left a taint on the whole series.

    Mine ran perfectly. I only sold it to fund a SCAR 16.

    As far as the mags go, yes, they use Sig 550 mags. But, since the lower is just a part (upper is serialized 'gun') you can swap to a 556 lower that takes AR mags, if you like.

    I believe CDNN may still be selling these for around $1500. The last few emails I received from them had the 551 listed and I'm pretty sure they were less than $2k.

    As far as the rifle itself goes, they aren't very popular and don't have the best reputation. They are sort of bastardized versions of the real 550 series of weapons, and the Sig USA built versions aren't near the same level of quality of the real 550 series rifles are. You can get one hell of an AR for that price (well, used to be able to a couple of months ago), but the 551 is certainly unique.

    The 551A1 is a really nice rifle. As the whole is more than the sum of its parts, I would encourage you to look it over really well.

    It uses proprietary magazines, which rock in like the M14 or G3, but are inherently ambidextrous for the magazine release is located in front of the trigger guard.

    Has cold hammer forged, nitrided, barrel, 1 in 7 twist, unique flash hider. Mainspring over oprod/piston. Two position gas system. Pic rail for optics, and foldable "swiss style" stock.

    It really is a neat weapon.

    As another contributor has said here, upper receiver is the serialized part, so you can change out the lower to one which accepts AR15 mags if that suits you.
