Suppressors Ocm 5 on 6arc

What does your end cap opening measure? The OCM5 is on my near range list of suppressors to get and I'd love to run it on a 6ARC coyote gun, but I've read it's real tight on clearance.
 
The AEM30k is the same length as an AEM5. Definitely okay with 6mm.

Supposedly the AEM5 stock has a bigger hole. If it was gonna be dedicated for a 6ARC I’d just get that vs hoping the other works. No manufacturer will say it’ll work.

I want to say I’ve seen what Baccarat is talking about also. I have daydreamed about doing the same.
 
not sure if it helps but I bought a Dead Air Lazarus 6 so I could try one of the 6mm variants in the future. Haven't looked into it enough to know if ARC, MAX or some other variant might win out for me. I guess even a 6mm CM can be shot thru it.
