Colt CM762

[Mike Miller]

I have a CM762 and a Dead Air Nomad waiting for a form 4. I would like to reduce the gas flow for 100% suppressed use with a gas block insert. What would be a good gas port size to use? I'm not able to find good data for suppressed 308 gas ports like I can find for 556.

Shoot it suppressed first and see if you really need to mod the gun. It could be gassed just fine.
