I agree over gassing can be part of the problem as well. Bolt velocity is rather high as it slams into the bottom of the stroke. Set gas block by shut all the way down and the alternatively fire rounds with one rounds in the magazine. It will not get to the bolt catch and hold it open until enough gas is cycling to give the bolt enough velocity to far enough back in the stroke. Ounce the bolt catches go another 1/2 turn. If you set it up for non suppresses there will be more gas suppressed. If you shoot only suppressed set it up with your can on. If you go between both you will have to find a happy medium. Doing this and changing the ejector spring to an AR15 spring will get you there.

I figured I couldn't afford the optic to go the precision route, and making a hog-buster could be fun for 3gun. I've always liked the stubby little barrel sticking out of the end of a dissipator...so I figured a 16inch barrel inside a 15 inch handguard might be kinda neat. Boy, if I had the resources and dedication to track down a fixed sighted, carry handle dissipator .308 upper that would take rifle length triangular handguards...that would be sexiful! Instead, I came up with a "resto-mod" sort of impression of a .308 dissipator. 
which I like 
The stock is a SOTAR-Surplus Magpul. I figure I need to put a sling on it and change the pistol gip to something Magpul (just...cause?). I'll have to figure out which version I like...too bad there aren't any gun shows coming up to feel them up 
As was previously suggested, this rifle is pretty heavy as it is 
'Merica 
No worries about that, my friend. 
) decided that even AR-10 receivers had to go through 77r and 7 day wait starting this January. I don't have any documentation of that claim, other than what my LGS told me. Don't worry though...this is MDS. I'll be sassily corrected if I'm wrong about that
