Should I drill out my gas port?

[TheSerialHobbyist]

If you have an under gassed rifle, the last thing you want is an adj gas block. Adj gas blocks will leak more gas than a standard gas block..

Interesting... I hadn't heard that before. But I had the same issue with the original (non-adjustable) gas block.

How did you verify the gas block was correctly aligned?

Careful measurements with calipers to ensure that the hole in the gas block centers over the gas port.

If you insert a cartridge that is known to be the correct size fall out of the chamber easily or does it stick in the chamber..

It falls out easily like it should.

Do you have an O-ring on the bolt's extractor??

I'm not quite sure what you mean... The bolt has the three rings like this: https://www.grendelhunter.com/product/6-5-grendel-bolt/

I've also tried three different bolts: the one that came with the rifle, the one that came with the Satern barrel, and the replacement that Satern sent me because the extractor on the first was too weak.

Can you put a cartridge in the bolt by hand and it moves freely in and out?

Yes, I can put a cartridge in and take it out easily enough, with the extractor gripping properly when it is fully seated.

Does your bolt freely insert into the barrel extension when chambering without hitting any of the locking lugs. Try this very slowly as you cycle the rifle by hand and you will be able to tell..

Yeah, it seems nice and smooth to me. I can't feel or see any issues.

Does the rifle cycle without problems when done by hand, no rough sections like hitting the trigger?

Yep, works just fine if I cycle it by hand. Everything feels smooth.

Did you test the gas tube for cracks or a worn button?

No, I haven't. What/how do I check? The gas tube was new and I didn't notice anything wrong. But I didn't carefully inspect it.

How did you check the gas key?

Just felt it to make sure it wasn't moving and that it was staked properly. Is there something else I should check?

If you over size the gas port, then an adj gas block or a way to mitigate the gas will be necessary..

I don't mind using the adjustable gas block for that purpose. I just want to make sure I'm not doing something stupid by drilling it out.

I've been tearing my hair out for several weeks trying to figure this out and don't know what else to try. If you have points on the things I might have overlooked above (like the gas tube), please let me know!
