Frequently Asked Questions

What were the W+F Bern E22 and C42 rifles designed for?

The W+F Bern E22 and C42 were prototype rifles submitted by Waffenfabrik Bern to compete in the Swiss Army trials to replace the Stgw 57. They aimed to offer a more modern, modular, and smaller-caliber alternative to the existing service rifle.

What were the main differences between the W+F Bern E22 and C42?

The primary difference lay in their chambering: the E22 utilized a proprietary 6.45x48mm GP80 cartridge, while the C42 was chambered for the standard 5.56x45mm NATO. Both were offered in rifle and carbine variants.

Why were the W+F Bern rifles ultimately rejected in favor of the SIG 541?

Despite innovative features like a quick-detach barrel, the W+F prototypes were rejected due to perceived inferior accuracy and mechanical issues, notably a charging handle that was easily lost during field stripping. The SIG 541 (which became the Stgw 90) proved more reliable and accurate.

What notable features did the W+F Bern E22 and C42 possess?

These rifles featured a quick-detach barrel system for modularity, folding stocks, large trigger guards for use with gloves, and a diopter sight system. The full-length versions also included an integrated bipod.
