GAS BLOCK

[ray1970]

I've used a few set screw type low profile gas blocks over the years. My preferred method for installing these and not worrying too much about them is as follows.

Make sure the gas block is properly oriented and aligned.

Snug both set screws.

Remove one one set screw and drill a dimple into the barrel through the screw hole.

Reinstall that screw firmly with some loc-tite.

Repeat the procedure for the other set screw.

Finally, take a hammer and a punch and peen the gas block over the set screws.

Never had one come loose or rotate using this method.

You need to chop the fsb down so you can get the barrel nut on/off. The gas tube comes off to get to the nut.

Interesting technique.
You mean I have been doing it wrong by removing the pins, removing the FSB and gas tube as an assembly and then removing the barrel nut?

I learn something new everyday as well.

Don't need no stinking punches

Here's one Bert chopped down for me. It turned out very nice. We cut it down to have a mid-gas system on a "dissipator" style upper.

Damn, I have seen a lot of bobbed sights.. Bert did a hell of nice job there.

Doh. Brain fart by me. That nut isn't gonna clear.

Yep. He's a perfectionist with everything he does. I was going to cut it down myself but he convinced me to just let him do it while he was turning the barrel down and pinning the new front sight base.

Glad I let him. I do a pretty good job of making them pretty when I chop them but not that pretty.

Thanks for info. I think I can go the bobbing route... But will it go back into place once I remove the end cap? I will need to replace the barrel nut for the new FF

The pin/screws keep it in place.. Not the cap. You should be good

Are there any groves for for the gas block to rest into when I put it back? Or just mark it?
