Hi, mates !
Are the swiss M57 and the swiss M90 bayonet compatible on both weapon´s ?
Thx. in advance,
Very old post, but it can maybe help other people.
The M57 can be fix on the actual Swiss Army assault rifle, the SIG-550 (Fass90). So I'm quite sure the M90 con be fix on the StGw 57 (Fass57).
the bayonet 90 fits the rifle stgw 57 as well.
