A reader, Nooky, posted this photo of the prototype 7.62x39mm SIG550 that Swiss Arms developed a few years ago but never put into production.

Gun Blobber posted this photo comparing an AK bolt with a SIG550 bolt …

Many more cool photos at GunBlobber.

As you can see, very similar. Nooky also posted this photo comparing the action of the SIG550, AK and SIG552 …

More info about the upcoming 7.62×39 SIG550.

[ Many thanks to Noody, TroubleShooter and Gun Blobber for the info. ]

    The problem with the Sig 556 isn't if it is reliable. The problem was marketing. The Sig 556 is reliable but the marketing was terrible.

    They shouldn't have put AR stock and cheap hardguard on the carbine. If they had put the original 550 stock (or something that is not AR related), added 1913 handguard rail, and kept it below $1,000 it would have done well.

    Even if they make it the best of the best you still have to deal w/ inferior ammo availability. Heavier bullets wll allow that round to be more accurate. and penatrative. i hear that in europe you can find 7.62x39 with heavier grain bulllets, and not made by wolf. That round has such great potential I just wish someone would come out w/ heavier grain bullets for it.
