Barrel Compibility


Recommended Posts

Looks like I'm finally getting an AR-10 B series upper to go along with my lower.

The reference guide at https://308ar.com/ar-10-308-ar-compatibility-reference-guide/ says that I need to find a barrel with an Armalite compatible barrel extension and must use an Armalite bolt carrier and bolt.

I've read in other forums that as long as you have a properly matched barrel, bolt, and carrier then you can use either setup in either Armalite or DPMS style receivers. What is the opinion around here, or is it not a matter of opinion?

Can I buy a 6.5 Creedmoor barrel with matching bolt from JP, along with their bolt carrier, and use all that in my AR-10 B series rifle? Or am I stuck with a barrel from Armalite? I don't see any other companies making barrels with the Armalite style extension, especially not in 6.5 Creedmoor.
