Picatinny to Picatinny rail adapter.

Guys, I'm thinking of doing this for my Bushy, but it would work for any rifle with a under foregrip Picatinny rail.

I'm thinking about taking this scope mount;

And then having a gunsmith create a picatinny to picatinny adapter, so I can mount the actual Steyr M40-A1 to the fore rail of my Bushmaster Bullpup, to use the Pistol itself as the foregrip. So in actuality, should the need arise, I can use the rifle for long range, while taking care of short range problems with the .40, all at the same time.

The Scope mount it'self seems to be made from stern materials, and run on both sides of the slide, so they will provide enough support the front of the bullpup, which isn't that heavy to start with. The final picture should look something like this;

What do you guys think?

 

The IGB mount attaches to the P'rail on the frame of the Pistol, not the slide, it comes around the slide on both sides, in fact, in the picture, the slide is not even attached to the pistol to show this. The pistol will not move at all when firing. Take a closer look in the upper picture.

The mount is also designed not to interfere with brass ejection, that's why I want to use it, and not make my own. I can always reinforce it if needed, but it doesn't look like it would need it.

 

I've got a Gunsmith/Machinist looking into this, it may constitute an SBR or AOW, but that would just constitute extra Taxes, and paper work to do this. I'll post more as this topic matures.

 

Well, I got to see a pic of a prototype, half finished. I'm likeing it so far, the smith is building a slide on style with allen set screws. The finished producht will be more like what BSA Red Dot scopes use to attach to the frame, just to make it easy. Or, I may redesign and go with a quick disconect.

 

I've just about finished the design on the adapter, and I like the way it turned out.
