The seller states this may make the Glock a short barrelled rifle. It sure seems to me that it does make it a sbr. Unless there is something I'm not aware of.

Not a legal comment but from the technical side:  I saw them at the SHOT Show this year and my first impressions were not good.  The thing is flimsy, wobbly plastic and the little spur that goes in the back of the handle to mount it does not seem like it would take much use, far less abuse.  It did get me thinking though so I'm planning to build one.  My plan is to buy one of the clamp-on extended mag wells, weld a 1/4" ID tube on either side and bend a wire stock from 1/4" stainless to slip into the tubes.  Best I could think of, still developing plan.

I made one way back in '91.

Yeah, yeah- I should of gotten a patent.

I coated the inside of the hole with oil and then fillde it with J.B. Weld with an angle bracket sticking out of it.

After removing it, I formed a stock out of conduit and attached it to the angle bracket.

I even drilled and tapped a hole in the epoxy plug for a set screw.

It worked nicely.  It made me kind of sick when I saw somebody making one.  All it ever did for me was get me interested in injection molding, and I'm now a mold maker.

Quoted: Sure does, that's why one company that makes these sells it with a ridiculously long "rifle" glock barrell that you install at the same time as the shoulder stock.

I don't think ridiculous does this justice...



That just looks awful.  Good idea, though.
