This video explores the W+F Bern C42 and E22 rifles, prototypes submitted for the Swiss military's Sturmgewehr 90 trials. The C42 is chambered in 5.56mm, while the E22 uses 6.45x48mm. Both feature a rotating bolt with a long-stroke gas piston, drawing parallels to the Stgw 57 in ergonomics. Carbine and rifle variants were offered, with interchangeable barrels. The rifles also boasted bayonet lugs, grenade launching capabilities, and bipods, features absent on carbines. Ultimately, these designs lost to SIG due to superior accuracy and a critically flawed charging handle design that was easily lost, a significant issue for Swiss reservist doctrine.
