Sig Sauer SIG556 in 7.62×39

November 4th, 2010 Leave a comment Go to comments

We just received a phone call from our contact at Sig and Sig Sauer is producing a SIG 556 chambered in 7.62×39. This new SIG556 will have a AK-47 bolt and it will support standard AK-47 magazines. Apparently these new models are in production and will be shipping from the factory in roughly four to six weeks. The SIG556 is modeled after the Swiss style 550/551 and one can expect the new model to be much like the existing models (with the exception of the bolt and probably the receiver). This model will have a 16″ barrel.

At this point, we have no photos or other information. I am not sure if the SIG556 7.62×39 will have a rail or if it will be configured like the classic model. I would expect more people would want a rail. SRP is not published yet but estimated at $1500 – $1700.

As soon as we have more information or photos, we will publish that info here.

What are your thoughts on this new model? We’d love the input… I would expect this to be pretty popular since 7.62×39 ammo is readily available and reasonably priced.

Update: this is NOT an AR style rifle – it is modeled after the Swiss style 550/551. I misunderstood the initial report of the rifle. The model number is R556-762R-16B.

Update 11-8-10 – Steve over at thefirearmblog.com just posted an update with some great info about the bolt and what the new Sig might look like. The photo below is from that blog post. On a similar but slightly separate note, thefirearmblog.com is an excellent source of firearm related information. If you’re a firearm junkie, bookmark that site or subscribe to their RSS feed.

    I think this is great, however I really hope it doesn’t use the AK-style magazine release. I much prefer the button release. Besides, AR-type 7.62×39 magazines aren’t all that expensive, but AK mags are cheaper.

    I’m pretty excited about this. I have a Robinson Arms XCR chambered in 7.62×39 and have problems with the C-Products mags.

    If this thing uses standard AK mags I’ll definitely be looking seriously at this as an alternative.

    While I understand the refinement that a Sig 556 can bring to the round, the sheer fact that one can buy an AK platform for a substantially less expensive price point (i.e., Arsenal SG-21 @ $700-800) weighs in my head.

    I forgot to ask you about the mag reliability when I was drooling over your XCR in Reno. I may hold off on my 7.62 conversion for my XCR until the SIG comes out.

    I am looking forward to the specifications of this new rifle. It’s a lot of money to spend on a rifle that I have minimal information.
    If it is much more accurate than a typical AK-47 and keeps the same reliability as an AK-47, I would definitely be interested. I like the fact that it will use Standard AK magazines.

    I agree that I would prefer to avoid AK magazines.

    I think the big advantage to the AK-47 mags is the low price and availability. If you had to buy a proprietary Sig Sauer mag, I’d expect it to be priced between $30 and $50… Pistol mags typically run in that price range.

    A chrome lined bore and chamber would be nice.

    much better than Rugers mini 30 offering

    With SGL-21s being available, I can’t imagine this having any practical use. It’s cool, though. It might be good for people that have, for whatever OCD reason, sworn against ever owning an AK.

    @Mike S
    Not to mention more reliable, good on C-Products for making affordable mags that they back with a warranty, but with the ready availability, multiple manufacturers, and high reliability and robustness of the design, AK mags are the way to go IMO.. I don’t like rifles that are dependent on a single source for things like ammunition or magazines

    One of the big points about AK magazines is the continual-curved design. Look at a 7.62×39 AR-15 magazine and you will see a straight section (to accomodate the AR-15 mag well) and then a strongly curved section below it. From what I understand, the strongly tapered 7.62×39 doesn’t like to feed through long straight sections of a magazine and this is part of the reliability issues seem in 7.62×39 AR-15s. Excluding items like the C-Products magazines, we’re basically left with standard AK magazines or something new & proprietary. People don’t like proprietary magazines because they are expensive and harder to find. Simply put, the AK magazine works and works well. Why reinvent the wheel?

    I bet it sells better then the SIG556. Use AK MAGS. I would never trust AR type mags in 7.62×39. Yeah, ak mags are slower to reload but you can’t beat the reliability and selection. Plus you get to use drums. I look forward to this

    +1 for wanting them to use AK-47 mags. If the price point is around $1100-1200 w/railed handguards(as pictured above) it will be an extremely attractive alternative to the higher end AK-47 offerings.

    As others have said, chrome lined barrel/bore is a must.

    Well it can have a monolithic free float rail, the barrel screws (not pressed) in, the selector is ambidextrous and easier to access, it has a some what adjustable trigger, bolt hold open on last shot, bolt release, has more accuracy and the gas system has two settings.

    There may be some more things I do not remember…

    Now if only some one would make 7.62×39 ammo w/ heavier grain bullets than are currently available. This rifle w/ heavier ammo would be a hell of a shooter.

    If it has a Chrome Lined Barrel(Without Chrome Lining it will not sell), If it has a Pictatany Rail for optics, If it uses Standard AK Mags, If it has the Collaspable side folder. If it has reasonable accuracy, 3″ at 100 yds with surplus ammo, If it is priced at $1500 or less, then it will sell. If it has all the above, I’ll have it on the shelves……….Kevin

    I think it looks really good! I like the original SIG 55X stock and lower. I don’t like AK’s, but I do LOVE my SIG556, and I also enjoy my Colt AR in this caliber. With a chrome lined barrel and chamber and the SIG55X original stock (not the one on the classic) and handguard (I grate cheese at home, don’t need it on my rifles), ability to take regular AK mags, and come in at a reasonable price, I will buy this rifle!

    Do want. It’s an AK that is refined for the modern battlefield.

    Like the idea. I have tons of ammo sitting around since I stopped shooting my SKS.
    And keep the hand rails, I agree, grate the cheese at home..If you need soemthing more than a sighting device and possible laser, go back to the play station.
