Gunsmithing 6.5 Creedmoor in a 308 platform?

[green338 2.0]

I've been eying a Creedmoor setup on my 308AR for some time now, but I still have a few questions.

I recently bought a Krieger Creedmoor barrel from Fulton Armory, but need help with the bolt...

Does a regular AR10 bolt/bolt carrier group work for a Creedmoor setup?

And, regarding PMAGS, do I need to do any modifications to the 308 PMAG?

Any help would be greatly appreciated.

A regular AR 10 bolt carrier group will work for a 6.5 Creedmoor but there may be timing issues, which can usually be resolved with changing your buffer spring.

308 PMAGs do not have to be altered and work fine.

Thanks for the response!

So, do I have to change out the spring from AR15 to 308AR if I change calibers?
