Stgw57 Assault Rifle, Alpine Style, Clear as Ice Edition

 Thanks to Chuck at GunLab for turning us on to this incredible post on the Swiss Rifles message board. As Chuck tells it, Dale got hold of, not a rare StG 57, but a rare2 cutaway version of the StG 57.

And then he posted a series of photos and a thoughtful analysis of this highly unusual rifle that replaced the Swiss Army’s rifles, light machine guns, and submachine guns at once. (Does that make it the Swiss Army Knife of rifles? Sorry, couldn’t resist.)

As Dale explains, there’s a lot that’s unique about the StG 57:

The Stgw 57 is an interesting battle rifle. The rationale behind this gun was to arm the infantry with an “universal weapon” that would replace the bolt-action rifle, machine gun and machine pistol. It was selected in late December 1956 over the Waffenfabrik Bern competitor for cost reasons (the SIG prototype costed only 495 CHF to produce over the 1100 CHF that the W+F Bern model required).

It was always expensive, and while a semi model sold in trickles in the USA, the high price and the rare (here) 7.5 mm caliber kept it from taking off. One of our team sergeants had one and it was a thing of rare beauty (we think he later traded it for an NFA registered 4.2″ mortar). A later export model was chambered for 7.62 mm NATO, but it didn’t sell any better.

It incorporates a modified roller-delayed blowback mechanism inspired by the StG45/Gerät 06 H prototypes, folding sights from the FG42, and a buttstock socket just like the famous MG42. In order to reduce production costs, SIG used innovative production techniques and rubber/polymer materials for the rifle’s construction, in an effort to minimise the number of machined parts.

 

The cutaway provides a rare chance to truly observe and understand this unusual weapon. The original post includes comprehensive photographs and explanations.

Of course, being a Swiss rifle, no compromises were made on the quality of the construction and overall robustness. Because of its heavy, welded, machined, stamped and brazed construction, the Stgw 57 weighs a whopping 6,5 kg fully loaded! Not only is the rifle one of the heaviest service weapon of the world, it is also one of the most expensive! Each Stgw 57 costs the Swiss government a grand total of 1000 CHF (of which 495 CHF are production costs and 75 CHF accessories).

 

In this post, we’ve placed a couple of selected images. But really, you must go there and Read The Whole Thing™; you’ll see many more images and each one has a deep technical description of what you’re seeing. Very highly recommended!
