I've designed an all new set up for the charging on the mg42sa. it's always been the problem on most builds. over the years I've caught hell, on this site for my modified ideals, ie. it doesn't look mg 42, well if your building a semi-- its not mg42, only a rifle. been awhile since I have posted here, will try to post pictures and share this with you all if anyone has an interest. it works so smooth, the two other builds I finished with this set up is fantastic.
