I need your opinion. I have a Dpms in 6.5 Creedmoor and I'm putting a suppressor on it. I want to put an adjustable gas block on and want some insight into what you guys recommend. Thanks for the input.

I used JP Enterprises low profile adjustable gas block on my heavy barrel .308 AR. Bore diameter was .936
Thanks for the input. The JP is what I've been looking at. I need the .936 dia. as well. Has it helped your rifle function any better?
Since Syrac does not make one in the larger diameter yet, the JP is your only good choice.
Here is the rub...JP blocks are INTENDED to be adjusted and then flooded with locktite. If you are shooting a few rounds here and there, not a big deal. Otherwise, you will have some issues. You could always machine an intersecting hole and thread it with a brass set screw if you want to be able to adjust it. The other option is machine a shoulder into the block at the adjustment screw and use calibrated washers and a lock washer.
I don't run mine suppressed, so setup was pretty straightforward for me. I like the ability to tune the rifle to ensure reliable operation but reduce the amount of recoil. My loads are pretty consistent, so I don't have to deal with the variations that different bullet weights/velocities can introduce but still pretty easy to adjust in the field if you are feeding your rifle different ammo.
I will be going back and forth between suppressed and not, will I have issues getting it to run consistent either way?

Thanks for the help Markco
I've never had any problems with a Noveske switchblock. If you can track down a 6.8 it might work but you will most likely need to cut your hand guards as well..
