Is that .22 conversion kit only for the select fire G3 or does it work on the semi only 91?
Will work in the G3 and the 91 but think you gotta fudge with itfor the 91.
No permanent changes.
Does not work in CETME due to the barrel trunion, could be made to work but I hate destroying history.
Designed for select fire but works on both of course.
