Adderini / MiniAdder reinforced stock attachment with picatinny rail

This stock attachment is much stronger than the original, extends the length a bit and includes a picatinny rail for attaching sights.

Even without using the extra screws this stock attachment is much stronger than the original.

In case anyone's wondering, I'm using the following adjustable “iron” sights, which work great:
