I just got one of these kits and have been thinking about it all day.
It seems do-able if:
1:The front bottom of the bolt was milled off like the UZI's.
2:The bottom-rear of the bolt was welded up, filling in the ejector rod hole and the corner of the bolt cut on the opposite side.
3:The ejector rod was replaced by a rectangular bar welded to the receiver tube with a CZ-52 pistol (Glock ?) ejector pinned on.
This would also double as the rear blocking bar.
4:Use a hammer / fireing pin set up like that used in the SEMI MAC-10's.
5:Use a stirrup trigger bar / Disconnector set up similar to that of the 1911 pistol.
This has the advantage of having no holes in the bottom of the receiver and the trigger pivot welded on where the FA sear hole is but the disadvantage is that whole thing would have to be made from scratch.
6:Weld a second blocking bar at the front bottom of the receiver at the trunnion so a FA bolt wouldn't go into battery(overkill?)
7:Perminatly fix a 5" fake can or flash suppressor.
What do you think?
