UBR stock removal Help Please. Slotted Screw will not budge.

[MindCrime]

I have a Sig 716 Precision that came with a UBR stock installed from the Factory. I want to remove it and install a PRS stock to make the Sig 716 PMR more Tactical. I prefer the Solid PRS stock over the retractable UBR stock.

I can not remove the slotted screw that holds the upper UBR tube piece onto the Tube Extension. I tried using a padded Vice and a very large long handle screw driver and could not budge that screw. I even put on some thick rubber gloves to get a better grip and I gave it all my might only to have the screw driver spin off. That screw will not budge. I tried a couple different flat blade Standard screw drivers with no luck.

I think Sig may have put some Red Loc-Tite on this screw because I can't budge it.

Any suggestions?

Thank for your help.

Hit it with a torch, then try to take it off. If its locktited in, a benzomatic propane torch will break down the Locktite enough for you to remove it.

Yeah and that will also melt the stock lol....

Yeah and that will also melt the stock lol....

Gotta admit.... The resulting fire would effectively remove the stock!!

I'll tell you what, send it to me and I'll remove it. I'll just keep the ubr as payment. HAHA

You just need a heat gun, a blow dryer may work, but it'll take some time. Once you get it heated up, it'll come out easily. Stay away from the torch.

Carefully drill off the head, slide stock off. Then you can heat it and remove the shitty stub.

If you drill it i will bet that the stub will screw out by hand. The taper of the screw is what is holding. Same as a tierod end or balljoint.
