Wood and a longer barrel are spec issues for you? You know the lmg version has a longer barrel right?
The cz858 were converted autos. The vz58 never had the gremlins and they were purpose built semi autos. If you want to use them as a comparison.
I had one of the first VZ58's from the first batch to Canada. A well used SHE-63 with epoxy and GREMLINS. Again you missed the point, it's fine to say it's "all military except for the fun parts" but I've experienced function issues with just such a beast.
So... are these going to be good reliable semi-auto versions, or are they going to be gremlins with the guts removed, or are they going to be REDESIGNED fire controls that are neither military spec or proven?
