CTGunner82 Posted July 20, 2018 Report Share Posted July 20, 2018 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. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted July 20, 2018 Report Share Posted July 20, 2018 You’ll be fine. As long as the barrel and bolt match, that’s what matters most. 98Z5V built a DPMS pattern rifle that uses all Armalite guts and barrel. It runs perfect.
