I’m probably gonna upset a few here but here goes.

Start with a good barrel and make sure the bolt seats square with the barrel extension when locked up. (I do not mean squaring the upper)

Keep the barrel nut torque on the low side of the range. I don’t like to go over 40’ lbs

Free float the barrel.

Feed it good ammo.

Everything else is to help you shoot more comfortably or to help the company that designed the latest gizmo make money.
