I just bought a new CMMG mk3 CBR. I've already got a scope for it, but I want BUIS, and I have not been able to find a solid response for what will work. It seems a lot say you should run a gas block height front sight and normal rear sight, but I see a lot of pictures of guys running normal troy or mbus sights on ar10 variants. I'm just looking for definitive answer, as I don't want to be running around trying to find what works. Thank you!
