Built a new M4 Carbine with a DD M4RAS and Adco CMV CL barrel. That's a nice shooting little gun. I can't say I really shot the comp well as I was prepared for muzzle rise wrestling the absent forces of recoil, pulling the gun down, when I probably should have just been holding it up. You can see that with Evan's segment too- his first burst actually falls instead of rises.
The fit to the sound suppressor is very snug. The gun was grouping maybe 2" from a Manfrotto on a Hog saddle at 100 meters with the iron sights. That's pretty good for XM855 ammo and MK1 eyeballs without a rear bag IMO.
The comps are very low concussion. Shooting the comp on my 14.5" barrel sounds no different than shooting a carbine with an A2 compensator, and we've actually sound metered them and found them to be within 0.5DB of that baseline to confirm that.

We wanted to comparison test the M4-SD II prototype against a couple other suppressors on the market. Obviously one sound meter to another, on different days, with different rifles and ammunition, the data is hard to compare, so when you have a couple products in the same place and time on the same rifle with the same ammunition, that helps.
The M4-QD SS NT-4 used in the test, and M4-SD II both have .305" bores at the front cap.
The test was performed at 24F with M855 ammunition, on a 14.5" ADCO suppressor threaded CMV CL 1/7 twist barrel.
