My friend is having some problems with a glenfield model 60- he purchased, when the triger is pulled it pushes the striker into the firing mechanism, only problem is his stricker is going under the firing mechanism. There is a little hole were a retainer would go to keep the striker held up but there is no retainer there. If anyone knows these guns good could u help me out, or does anyone have a schematic for this? Also I tried nurich gun parts schematics but it is not clear enough to see if something is missing.
