Swiss Firepower: The SIG AMT (STG57)

The Swiss are known for producing some of the world’s finest firearms, and the STG57 is no exception. The rifle served from 1957 until 1990 when it was officially replaced by the SIG 550 series, but today they are treasured by their owners in Europe and a few that trickled into the USA and elsewhere.
We take a rare look today at one variant designed for export known as the SIG AMT (American Match Target).

    I needed a cold shower after watching this. This should be labeled “NSFW” because of my reaction to this video.

  • ghost

    oooooooooooooooh no, recoil!!!!!!!!!!!!

  • mechamaster

    Somehow this battle rifle is more retro-futuristic and ‘space-age’ blaster rifle that belongs to ‘Star-Wars’ universe.

    The K31 style non-recipro charging handle is neat too.

    And It’s very interesting delayed blowback example like CETME / HK G3.

      I think Fallout every time I see one.

  • 1leggeddog

    wow nice gun! never knew it existed!

  • Harrison Jones

    Does anyone know what these go for when they pop up?

    How many were imported and were any 7.5×55 guns imported?

    • Clark in NM

      My LGS had one for $8k a couple of months ago. It was privately owned by a Swiss citizen who moved into the US, and it was still chambered for the original 7.5mm Swiss. Not clear if any were commercially imported into the US, but parts kits are available and out there (domestic receivers and barrels seem to be the missing link). The hell of it is that in Switzerland, the rifles cost a little less than 2000 Euro, about the same price of a new Norinco SVD, MAS 49/56, and even less than a standard, new AR15

        Actually they go for as low as $700.- Many people still have the select fire version at home from their service, back then the military often “forgot” about it 😉

        I’ve shot the 7.5 a lot when I was young with my dad but MAN is that thing heavy. The Swiss mags are huge as well. It’s an indestructible weapon explicitly conceived for World War 3, back then it was all about the single soldier and his capability to deliver rounds with minimal/no support from logistics or similar. It had to deliver 100% precision, 100% of the time. There’s a cost in terms of $$$ and weight, but few guns went so far with this concept in history – that’s for sure.

          I often say the 57 is a battle rifle dressed as an LMG.

    • Rusty S.

      Roughly 3k guns were imported into the US chambered in .308. 4k PE57s were produced in 7.5, unsure how many made it to the US

  • schizuki

    That rifle has Jennifer Garner looks: awkward and kinda weird, yet somehow totally hot.

  • Rusty S.

    I bet you would appreciate the ease of converting a 510-4 based AMT, Alex. Also I like this rifle for the replaceable locking recesses, making for a much longer service life.

  • Spiker

    Heres a couple I bought together some years ago. Pic taken in the condition I got them. Bottom one was pretty much shot out & I sold it on. The top one was virtually unused. I removed the aimpoint & sourced a new rear sight & couple extra mags for it. The flash hiders are not original & I’d love to get a real Sig one for it, also a bipod. A great rifle to use and as shown in the video accurate as any.

  • Julio

    Alex, I note you shot your groups -nice ones, too- using the winter trigger. Was this just because it was a novel feature that you couldn’t resist trying out, or because the extra leverage gave it a better feel that more than compensated for the weaker hold on the pistol grip than when using the standard trigger?

    • FarmerB

      People still use the 57 as a target rifle here at 300m – and just about all use the winter trigger as a matter of course – mainly because it gives extra ‘feel’.

  • derpmaster

    PLEASE let these be imported as surplus to the US soon. We need the K31’s bigger brother.

    • Doom

      it’ll be a parts kit monstrosity, they cut the receiver to scrap metal and torch the barrel into a bunch of pieces too. thanks America, for the retarded import laws!

  • HH

    I’d love one….but would have to chop that barrel down some if possible. I actually have 4 kits in the closet…waiting for when the kids go off to college and i have the time to build them out.

  • LetsTryLibertyAgain

    Thanks for the very enjoyable and informative video. It did a good job of conveying the shooter’s perspective.

    I have the much more readily available bolt action K31 that preceded the STG57, and it’s a great gun for its time as well – very accurate, and it has a lot of character.
