Sorry for the stupid post but,

But what would happen if you put a bullpup stock on an original semi-auto AR-10?

That depends what you mean by "stock". For example, if you had a bullpup lower that the upper fit on, it would be restricted. Why not non-restricted? Well, because the "bullpup lower" would be able to accept new AR10 uppers and would be classed as an AR15/AR10 variant.

Now, lets say you built a lower reciever that was bullpup for the AR180B upper. You would have yourself a cheap, ugly, non-restricted, bullpup rifle. The main thing is that it has to be a complete, one peice lower for the most part. You can't simply take an Ar180B lower and add linkages to make it bullpup, that would be a prohibited aftermarket stock.

I disagree... Some questions are indeed stupid.
Unfortunately the only way to tell for sure is to ask them.

wrong,there's no such thing as a stupid question,there's just some you shouldn't have to as twice

I used to own an original ar10 sudanese rifle, sold it about 10 years ago. How can there only be one in Canada now?

Your Sudanese was a CA. We were referring to original factory semi auto AR-10s. Only a handful were made, as opposed to the thousands of the Sudanese and "Nato" pattern rifles. There is one reported to be in Canada.

There is at least one. Either a member from this board. or some one that a member knows, owns one out in BC some where, if my memory is correct.
