The SIG SG 510 or Sturmgewehr 57 is a battle rifle manufactured by Schweizerische Industrie Gesellschaft (now SAN Swiss Arms) of Switzerland. It is based on the same roller-delayed blowback system used in the H&K G3 and CETME rifles. It is rugged and reliable in harsh climatic conditions.

Overview

The SIG SG 510 is in service in the Swiss Army with the designation F ass 57 (French, for Fusil d' Assaut 57) or Stgw 57 (German for Sturm Gewehr 57). It can launch rifle grenades from the muzzle.

A powerful and precise, but bulky and heavy weapon, it has been gradually replaced by the lighter SIG SG 550. The Stgw 57 is still in active service, but only with reservists who have not had a chance to be upgraded to the Stgw 90.

The Sturmgewehr 57/SIG SG 510-1 was adopted for Swiss military service in 1957. The SG 510-4 has been adopted by the Chilean and Bolivian armed forces. It is reported that the Chilean SG 510-4 were manufactured in two lots, the first partially in Italy by Beretta under contract to SIG and the second by SIG in Switzerland.

Although the SIG SG 510 is officially classed as a battle rifle, it is described by a number of users as a designated marksman weapon (in Chile with Supra 4x24 scope) due to the weight/accuracy/firepower for a standard service rifle.

For anti-personnel use, the Stgw 57 typical maximum range for consistent accuracy is 600 m (656 yd).

Every Stgw 57 can be equipped with a Kern 4x24 telescopic sight made specially for the Stgw.57 or a night vision scope. The Chilean ones carry a German made Supra 4x24 scope.

Development

The SG 510 derived from the AM55 battle rifle during the 1950s.

Variants

  • 510-1, Standard Swiss service rifle.
  • 510-2, Lightened variant of the standard rifle.[1]
  • 510-3, 7.62x39mm variant with shorter barrel. It has found no sales.

Upon completion of their military service, members of the Swiss armed forces can obtain ownership of their personal SG 510 rifle by paying an administrative fee. These "civilianised" rifles are converted to a semiautomatic only configuration. As of 2007, around 40 percent of discharged soldiers choose to retain their weapon, and the going rate for civilianised SG 510 rifles on the private weapons market is reported to vary between 40 and 500 Swiss francs.[2]
