Kinda what I figured. How did you get everything to line up; Stencils, the sidefolder itself?
One option is this sidefolder
It differs a "real" AK74 style buttstock by:
Not LOCKING closed, elthough supposedly it's very stiff and doesn't come open on it's own.
Being a bit longer, which increases LOP.
By being "drop-in" with just a little filing.
Not 10)% authentic, but a decent choice possibly.
Hope it helps.
