The STGW57 was the standard issued rifle for the Swiss Military Service from 1957 to 1990. It is a select fire rifle chambered in the same cartridge as this rifles predecessor, the K31. The SIG SG510 was chambered in 7.62×51. Along with sharing the same cartridge as the K31, you will notice the STGW57 has a similar T-shaped charging handle on the right side of the receiver.

Interestingly the STGW57 also had flip up iron sights.



For more information on the STGW57 check out this rather indepth look at the rifle on YouTube.

    For the Company that made the beautiful SIG P210, that is one ugly rifle.

        C’mon. It looks more like a late war prototype of something cobbled together our of parts of other guns than something developed after WWII for a standing army.

        It reminds me of the Charlton Automatic Rifle, which was a machine gun made from old SMLEs.

        • Anonymoose

          At least the inline receiver/stock design is an improvement over other setups of the time.

        • FarmerB

          Looks like? Stop watching Internet videos and go and shoot one.

          • J-

            I have shot one. They are very accurate and still loved by Swiss marksmen. Never said it was a bad gun. Just an ugly one.

          • Obama’s boyfriend

            I bet you said that about Sophia Loren too.

    • FarmerB

      Maybe not pretty. But the GP-11 ammunition is match grade and flies through the transonic very well (certainly better than M118LR) and the rifle itself is staggeringly reliable and DMR accurate.

      Really, the only minor shortcoming looking at it today was the sights. Although equivalent to the FAL’s and stuff of the day, it really benefits from optics we now have.

      In fact, when introduced into Swiss 300m shooting competition the SIG StGw-90 in 5.56 produced higher scores in competition, and so it was handicapped higher than the older StGw-57. But many older guys that had (vision) problems with the drum and post sights on the 90 went back to the 57, which was then. allowed to have diopter sights, as can still be be used on the K31.

      But the sight upgrade just showed the 57 to be that much more accurate than the 90, so now the 57 with diopter sights is placed into a different (higher handicapped) division to the 90’s. It’s still an awesomely effective rifle.

      • J-

        Some guns are effective but ugly (M3 grease gun), some are ugly and worthless (8mm Nambu), some are attractive but worthless (Mini14), and some are attractive and effective (1911).

        Just because it’s ugly doesn’t mean it doesn’t shoot well. I just think this is one ugly rifle.

        • FarmerB

          Yeah, you’re right, it’s ugly.

    • Yves in Switzerland

      Try it befire talking. It’s not a gun for a beauty contest. Very precise and powerful

      • J-

        ZOMG. Have you read my other comments? I know the gun shoots well. I know Swiss marksman still shoot it in competition. I have shot the SIG 510 import version. The 7.5×55 is an excellent round. I love my K31.

        I never said it was a bad gun. Just an ugly one. The P210 is a beautiful pistol. The K31 is a good looking bolt gun. Far nicer than the Carcano or Mosin Nagant. The Swiss can make very attractive guns. The 510 is not one of them.

        If I was going to shoot in a European MilSurp competition I’d rather shoot my K31 with diopter sights.

        I am allowed to comment on the aesthetics of a design.

  • Anonymoose

    “T-shaped”…the proper term is “beer-keg charging handle.”

    • Giolli Joker

      Much better choice of evocative terms.
      T-bone shaped would complement the mental image well, though.

    • Lou

      You are correct and must be an old timer like me! I have wanted one of these rifles for 40 years!

      • Anonymoose

        I’m not old. I just like beer.

        • Lou

          “beer keg” is what we always called the charging handle back 35- 40 years ago. They sold for around $2,000+ around 1980 which was a check of a lot of money back then -some new cars were $4,500 and a new Colt AR-15 SP1 went for about $425 at the same time. Mandell Shooter’s Supply was one of the importers and I ended up meeting him (Mandell) at the 1989 SHOT Show. He was also the original importer of the SIG-550 rifles.

  • Klaus Von Schmitto

    I so wanted to buy a parts kit when Apex had them but had no idea where to find a receiver.

    • Stephen Paraski

      Good luck with a barrel.

    • Seth Hill

      If I could find a parts kit, I’d buy it to at least have it. Then if I had to make my own receiver I will.

  • Buffalo_Samurai

    It was issued in 7.5×55 Swiss for the Swiss…

    • int19h

      To clarify, the post claims it’s 7.62×51.

      • Stephen Paraski

        SG 510 was .308 NATO. Stgw 57 is 7.5×55, and APEX has a few Parts Sets for sale, sans barrel & receiver of course.

        • int19h

          Thank you for this important clarification. These two are used here as if they were interchangeable, but apparently there were more differences, not just the caliber.

  • FarmerB

    It’s a “light” machine gun dressed as a battle rifle.

  • Ark

    This is my white whale.

  • Giolli Joker

    Thank you, great links.
    Ian’s video, posted here recently, with full disassembly, is cool as well.

  • iksnilol

    Weirdest rifles ever issued in terms of looks.

  • Rob Vogel

    I spent about 800 days Military Services with this gun, I loved it…The US introduced in same time the M14. If you discuss now if it is nice or not….compare both

  • M1911

    A friend of mine has one of these and let me shoot it. The sights look like they have the precision of a Swiss watch. It is a seriously cool rifle.

  • Geoff Timm

    As was said at the time, “A triumph of precision manufacture over design.” Geoff Who has been around awhile.

    • Ken

      The Swiss MG51 is an example of that too. They basically took the perfectly fine German MG42 and made it heavier by manufacturing it with milling instead of stamping. They also replaced the roller locking with flapper locking.

  • FarmerB

    Yep, and I still shoot both of them in those same mountains – although not being Swiss I didn’t do the military service with it. Last week, the 556 was starting to run out of puff about 600m or so (ACOG optic) but the GP-11 whacked 9 from 10 chest targets at 800m (although not in a 57, mine is still in the raw=no optic).

    • Peter Balzer

      Good job! Where do you shoot up in those mountains? Wichlen, Hongrin? With what group? Maybe send me a private note under and we can hook up sometime

  • Lockmazter

    So, this was issued to Swiss military, but does anyone know what they issue to civilians? I’ve been told that it is mandatory that every household in Switzerland be issued a firearm and receive training on same. Does anyone know if this is true?

    • Fergus

      Civilians own them in Switerland, and semi auto versions can be purchased there and in Germany.

  • Fergus

    There are tons of these in Switzerland and a firm in Germany still manufactures them. Too bad they are banned here.

  • Hank Seiter

    I own and shoot both the PE57 and the Sig AMT. Excellent rifles, reliable, relatively soft shooting, accurate and … exceptionally expensive! But if you can find one and can afford it get one or the other depending on your visual tastes.

    The PE57 certainly looks like the offspring of an MG-42 and I suppose there are a lot of mechanical and engineering similarities with respect to stamped steel receivers, folding sights and delayed roller lock bolt head and carrier. I’m sure the Swiss took a good hard look at Germany’s Stg45 proto-types and the MG-42. Unlike the CETME/G3/H&K91, the Sig510 series appropriately sized the bolt and bolt carrier to handle the power of the 8mm Mauser/.30-06/7.5 Swiss/.308 battle cartridges, so the Sig’s bolt and bolt carrier are relatively massive by comparison to the CETME/G3/H&K91 roller lock bolts which were originally designed to work with the post-war reduced caliber 7mm cartridge that was thought to be the newest modern battle round until the 7.62×51 won out in the mid-1950s.

    The softest shooting .308/7.62×51 I’ve ever shot (other than a very finely tuned heavy barrel FAL that I kit-bashed using an Imbel receiver) is Smith Manufacturing Group’s (SMG) clone of the German paratrooper FG42. It’s available in both its original 7.92 Mauser configuration or the 7.62×51. And extraordinary piece of weapon design and, unfortunately, relatively expensive. But compared to the $300,000 cost of a vintage FG42, I suppose $4800 is chump change.
