Thanks all for the clarifying info.
Hey sorry about late responses, been busy at work and catching stuff up around house.

That is the correct RE Im using with Armalite's AR10 Spring (they use it for Rifle and Carbine AR10s) and a H Buffer.

I run an adjustable GB under my CMR, but its not a Sentry. Its a Odin Works its a close fit but doesn't touch. I think I have pics somewhere. If not then I'll post some for ya.
