Not sure if this is the right place for this topic:
I was wondering if anyone knew of a semi auto Ultimax 100 ever being built from a parts kit, or if it’s even possible, i.e., if there is an “approved” design for such a build. The Ultimax 100 fires from an open bolt, which I know makes things a bit… complicated. But I know there are some semi-auto builds made from parts kits of open bolt guns.
Much appreciated.
