Mossberg 590 Picatinny Rail Adapter

Having bought this airsoft shotgun replica I found that it had no means of aiming as that it is a "breacher" model.

Wanting a way of attaching a sight of any kind I designed this adapter that only needs 2 slightly larger M3x10mm screws than the original ones in the side of the body.
The front of the adapter is held on as a sliding clip.
