SIG SAUER® is offering several variants to its tactical platforms. NEW to this lineup is their new SIG551-A1, chambered for the widely used 5.56 x 45mm NATO caliber using Swiss Polymer magazines. The SIG551-A1 features a distinctive swiss folding stock, and an M1913 rail for accessory attachment. The 16” barrel features four-groove rifling and a twist rate of 1:7”.

Am I mistaken or is this just a Sig 556 with new furniture and Swiss mags? Didn't the Sig 556 FAIL badly?... Or is this a better rifle than the 556?...

Help me understand this... What exactly is the new Sig 551 -a1?....

The 551 weighs considerably less, folds up smaller, and costs about $800 more. Otherwise, they are substantially the same rifle:

The original 551 and 552's made by SwissArms in Switzerland were almost unbreakable. (I say this after working at the SIGARMS Academy for 4 years and having 1 of each assigned to me.) Can't speak to the quality of the U.S. based products - have heard that everything is being outsourced all over the globe.
