Gentlemen, I have an update for you regarding the Dissent.
I got a hold of the right allen wrench, it's a 3/32" not the 5/64" that is listed on CMMG's gas block info page. I also ordered some different ammo and that showed up earlier this week.
So I get the allen wrench and screw the adjustment screw all the way in and record the number of clicks, 18-19. I then back it out 10 clicks and fire a round. Bolt doesn't move at all. I then back out 10 more. Gun goes bang and cycles the next round and ejects the empty about 3 o'clock. I inspect the receiver area for dirtiness and there is none. I then shoot a couple more and zero issues, spent brass is still landing at 3 o'clock so I turn the screw out another click. We are now out around 2-3 clicks from factory setting.
Should note that I am shooting Winchester Super Suppressed 200 grain. I then load up 10 rounds and zero issues and no sign at all of powder flakes. Load up another 20, no issues, repeat, no issues and no sign of powder residue. Sweet!
I then load up some of the Federal 220 grain that I shot the original time and here is the weird part, they cycled fine and showed no sign of dirtiness. I can't figure that out but I'll take it!
So what in the hell caused the gun to be so dirty initially but now it runs fine for 50-60 rounds and no sign of powder flakes?
Who knows, but at least you've got it working now.
I set mine up to eject the subs around 4:30. That puts my supers at 3:00. Maybe not ideal for the supers, but it runs both without any issues so I can switch back and forth without any adjustments.
I made a crude vid yesterday to try and see how the pistol operates without the use of a brace. And as noted in the comments someone pointed out the inconsistent brass ejection.
And I obviously had a brain fart and was off 90 degrees in my incorrect description of ejection at 12 o'clock.
Do you think the ejection variation is ammo, gun or related possibly to inconsistent pistol grip?
And obviously I don't intend to actually shoot the pistol like this in any serious situation, this was simply a test.
Trying to remember but I think the gun had more consistent ejection with the brace but I'm not sure.
And please don't make fun of my winter beer belly...lol
Thanks Shane. It was beyond awkward shooting the pistol with the scope like that but I had to try just to see what the hell would happen.
Just ordered some more subsonic ammo(Sig 220's and the Winchester 200's I was shooting in the vid) to test out in this thing and will have to remember to set the camera up when testing the ejection.
There's a sling technique you can use to get a lot more stability even without a brace. Basically, pushing the pistol forward against sling tension to tighten everything up.
I've played with it a bit with a AR pistol. With the AR style the buffer tube on the cheek makes another point of contact to help stabilize the whole works.
