Possible to remove SAM7K-03 pistol tube?

[icantdrive55]

Awhile back I picked up a SAM7K-03 and it came with a sig brace from the factory. I'm trying to remove the tube, but not sure where to start.



Any ideas? It seem welded together...

Inside the hollow tube, which you can access by removing the brace, there should be a bolt holding it in place.

If not, that receiver plates may be bolted on from inside of the back of the receiver.

Yeah, I think it's bolted and welded down... Not sure why they would do it this way... I guess I may have to cut the tube off.
