Do you have a recommended way of opening the gas port?

In my opinion, even the 1.4/1.6 needs a wider difference when running suppressed on a 10.4 as the 1.4 setting is overgassed even with a low back pressure suppressor like the Socom.

I had ADCO do my barrel work before sending it to WMD for QPQ refinishing inside and out.
For 14-16 inch barrels, you can get one of the 11" handguards with the cutout for $200 for the next couple of days at Brownells. I got mine yesterday and it was in great condition, only a couple of small dings. I haven't seen any other places selling the 9" handguards with the cutout.
