Advise on setup

[A6G]

Will there be any issues using an AO precision 5.56 bolt carrier, with a Toolcraft 6.5G bolt (DLC if that matters), and a Colt H2 buffer?

What buffer spring would be ideal?

Gas block would be a Superlative Arms adjustable bleed off style.

I appreciate your time and response!

Any 556 bcg will work with a 6.5 grendel bolt.

If you have adjustable gas you can run any buffer/buffer spring setup you wish because you can tune the gas to it.

Thank you for the response, A5B, much appreciated!
