Adjustable Gas Block vs Tube?

[Clod Stomper]

Thanks for all the good ideas everyone. I'll ruminate on it and come up with a game plan. I have a well equipped man cave and bits as as small as .5mm and taps down to 0-80. One of my drill presses is set up with a B&L stereo scope for fine work. I just thought the obstructing screw would have to be at least a #6 to do the job right and that's probably not thinking outside the 9 dots. I'll figure something out, or simply buy a block. All kinds of options...

I have done it. And it sounds like you're set up better than I. I believe I used a #6 screw. It won't completely cut off gas, but I didn't want to do that anyway. To shut off the gas completely, you'd need a #8 and enough "meat" in the gas block to drill a hole that large.

It's a straightforward operation. Just make sure to drill between the bore of the gas block and the gas tube hole. You can get closer to the gas block, like LRRPF52 said, but beware. If you get it too high, where the screw will contact the gas tube, you'll have to cut a bit off the tube, and the skin on those gas tubes is super hard.
