Best AR-10 Bolt Carrier Group, Barrels and Ammo - A Discussion with John Paul

Originally published at:

We recently spoke with one of the great AR innovators, John Paul from JP Enterprises, about the small, but critical things that need to be at the top of your mind as you build the best AR-10 possible.

John Paul is one of the top gas gun builders in the country. His hardware isn’t cheap but the guy knows his stuff. The action on his rifles feels like it on roller bearings.
