So I just completed a form 1 with a quietbore, and the sound reduction is great. As in, no pain or muting in the ears (not that I'd do it a lot) whatsoever good. I'm very pleased.
But the blowback, god dayam. The overwhelming smell is one thing, but the stinging in the eyes... Yeah, I'm going to be getting an adjustable gas block.
I see that Aero makes one, but any suggestions are welcome. As well as tips and pointers that I'll need...?
Bonus question: with a long rail, being unable to get calipers over my barrel, anyone happen to know what size an 5.56 LWRC DI barrel is?

Getting an adjustable gaas block is the right move. This will allow you to tune it so that you have the most gas going through the suppressor, and the least gas going into the action and your face.
I recommend one that uses a set screw for infinite adjustability, as the detent based ones don't always offer enough fine tuning to really eliminate excess gas.
Also avoid any bleed off type gas blocks - you don't want gas bleeding off as that bypasses the suppressor.
Once you have the adjustable gas block, you can further reduce gas to the face by reducing the weight of your BCG and/or buffer and/or spring tension. Any of those things will reduce the amount of gas needed to cycle which means you can tune the gas down even lower, if you want.
You can also look at special gas buster charger handles, and/or apply the RTV mod to toot charging handle.
Do all of the above, abd I guarantee you will not be having any gas issues in your face
