What the SIG762 (7.62x39mm SIG550) probably looks like
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 ...
As you can see, very similar. Nooky also posted this photo comparing the action of the SIG550, AK and SIG552 ...

[ Many thanks to Noody, TroubleShooter and Gun Blobber for the info. ]
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 7.62×39 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.
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.
I’m glad that someone is addressing the needs of AK and 7.62×39 shooters. If the price is reasonable and it shoots an acceptable MOA I would consider buying one.
@subase, if you hadn’t corrected your previous post, I would have tracked your ip and sent a squad of elite swiss assassins to kill you and eat chocolate on your still warm body.
but everything’s fine. For now
I mean SIG 556
Sig Sauer USA is the bling king. Might as well have Lady Gaga make an AK.
The SIG 550 is AK trash.
I can never get my head round the people who say there is no point developing another rifle that fires 7.62 short, that you should add a buttload of “nifty” accessories to an AK.
You can’t polish a turd but you can roll it in glitter I suppose.
While I agreed this would be a potentially great platform, I didn’t like the heft my 556 SWAT’s quad-rail added to the already nose-heavy design. If I were to get one again, I would go with the lighter, traditional polymer grips. Could add short-rail panels later if needed.
I still do not want their folder receiver! It is too limiting… Some states do not even allow folders. The AR stock receiver is better. I know some people want the Classic version just because it look like the Swiss 550. I rather have quality stock options than a rifle that is trying to look like one from the earlier days and yet not the same quality. Just buy some airsoft replica or spend huge money on buying the real lower receiver.
The easy way is for Sig to just continue to manufacture both lower receivers. But they do need to modify the AR stock receiver to try to bring the tube up a little. The grip as well and a little forward.
I really want that gun Nooky is showing! It is like the AK I would want.
I think the design of the operating system would be just as reliable as an AK-74. The only difference is the spring is placed in the front. The receiver could be shorter because of it. Down side to the design is that it places more weight to the front. That is why they have thinner barrels to compensate.
It does appear you could shorten the piston system on the Sig 556 by 1 to 3 inches. Have a 8″ or 9″ monolithic rail that extends on top and attaches to the gas block, would give you about a 18″ sigh radius. Should be enough rail space except for DMR setups.
They already have two gas lengths for the Sig 556, short and long, why not just add one that is in between?
They should have three versions: short gas with a thin enough barrel to still use suppressors optimally, mid-length gas with medium contour barrel, long gas with heavy barrel.
Why didn’t Swiss Arms put the Sig550 into production? Looks like a winner.
Your welcome.
Sig also did prototype with the Sig 510. Like that one. 7.62×39 SIG 510-3

I took that photo myself, the rifle was sold for more than 8000$
Nooky, very nifty!
Here is another photo of that prototype.

Overall it look more like a 551 LB than a 550 to be honest.
Like the one on top here displayed (notice they mixed up the nameplates)

The rifle is so much tacticool, you can’t really see it, but i can’t find another 551 LB with B&T handguard.
Nooky, thanks again for the pics.
How ’bout a SIG545? Or a SIG6.8?
I’ve never shot a SIG rifle before. But comparing with AKs, which one is more reliable? I would’ve imagine that SIG would have the accuracy. With a 7.62×39 round, it would be a cheap and deadly combination. But will it keep up with the reliability of an AK? afterall, AK can use even most abused rounds and still function with minimal stoppages. Will the SIG perform that?
“I don’t see why Swiss Arms or SIG didn’t develop it more. It could have been a great export rifle.”
Who would have bought a Swiss AK for the price of several AKs?
quality AK = $800
MI rail = $130
If they can make it as reliable and tough as an AK and around $1200 I think that will be a fair price.
That would make the upgraded ergos etc a $250ish premium.
I’d pay that for a better AK
7.62 version can be amazing if they do it right. If they use the rocking insertion of magazines (using ak mags it should) you do not have to worry about the magazine release being to forward like the 556 version. I think the rocking magazine is better than the AR-15 design because you do not have to worry about whether it is seated. A trained individual can change magazines just as fast as AR-15.
Two things I find the 556 version that are not good: the plastic on the Sig rifles are not good quality and the non-chrome barrel is too thin for continuous fire. If they could make good polymer, couldn’t they make the lower (of the 5.56 maybe 7.62) out of it like the ACR & 16S.
I do not like their folding stock receiver because of the stock itself and lack of options because of it. Would it be better to fold to the left, not to block the charging handle, but you have no choice because the receiver says so. With the AR receiver they had you could get an ACE adaptor and had many more choices because of it. Fold left or right or not fold. Single point plate. Any AR stock.
Barrel to medium contour would add weight to a gun that has most of it to the front because of the piston — better to be able to sustain fire longer and retain accuracy. If you want a very light gun get a DI AR-15.
“My” Sig 556 would have the AR style (maybe polymer) receiver with an ACE adapter folding to the left with a Noveske end plate and Magpul stock with VLTOR storage tube. Chambered in 7.62 and take AK mags. Medium contour barrel with Vortex flash suppressor and Troy continuous rail.
The nice thing is even I believe Sig Sauer in the U.S.A can make a decent AK.
Another thing is we already have a modern AK with the Robarms XCR.
The trick is for Sig to make an AK in between the XCR and your standard russian AK. Sort of a step above the new Galil Ace or AK 200

I think the important thing to remember is strength and reliability, the hallmarks of the AK design.
If this gun can reuse AK mags, I would seriously consider this as an alternative to a milled receiver AK.
After all, I already have a stamped (cheapie) AK. If I was going to spend more $$$ for a 7.62×39 caliber gun, this one merits consideration (esp over a 7.62×39 AR15).

I don’t see why Swiss Arms or SIG didn’t develop it more. It could have been a great export rifle.
in Fact, FASS90 or Stgw 90 are base on SIG SG541 in 5,56 . The SG550 is civilan name of the rifle.
FASS90/Stgw 90=> PE90 or SG550-1
FASS04/Stgw 04=>SG552-1
FASS07/Stgw 07=>SG553-1
“-1″ for GP90 amuntion with 10″ twist
“-2″ For SS109 amunition with 7″ twist
The Weapon system is born with the joint devleomepent in 60′s of Berretta with the AR70 and SIG with the SG530. The next version is SIG-Manurhin SG-540/542/543 design for export. In 80′s switzerland chose the SG 541 (rename SG550) with some modification.
That looks great and definitely could excel over a traditional AK imo.
This in before half the people that can’t understand the difference between this and an AK.
If they can manage the same reliability, but also offer improved controls/mag release/safety, a REAL platform for optics and not that joke of a railed top cover, a well designed rail (vs an afterthought), concentrically threaded / high quality barrel, a modern folding stock with a cheek weld, and good iron sights this would piss all over an AK in every respect except the price.
And it only took 60-some years to do it.
Considering that the Sig550 is a 5.56mm and is named “550″, wouldn’t the 7.62mm version be named the Sig760?
Thousand, SIG556 is the US civilian version of the SIG550.
According to Wikipedia, the SIG552 is been replaced by the SIG553, due to poor reliability of the recoil spring behind the bolt.
The SIG553 is like it’s oldest brother 550, with the recoil spring wrapped around the piston.
I really like the concept. I’d be very interested in adding one to my collection.
Gun Blobber.
I’m interested to see if the Sig 762 will use a magwell or require AK magazines to be rocked in as conventional. I don’t see a way around it without modifying the mags.
So essentially the SIG762 is going to be a higher quality better ergonomic AK-47. Depending on price this might be a buy for me especially considering the price of some of the higher end AKs. I mean I love the AK but once you buy a high end gun and spend all the money to change out all the standard stuff so you can have a better stock, good place to mount an optic, etc this would be a win.
