Airsoft Stock locking tab/button for A&K Masada

A quick part I designed to replace the broken one on my Airsoft A&K masada.
The sides are slightly oversized to compensate for shrinkage when printing in ABS, you may have to shrink them (or file them down) if you print in PLA or nylon.
No shaving or fililng should be required if you print at 95% scale, it should drop right in and work like a charm.
