for those that are running switch barrel rigs... which is the better action wrench, the rear entry or the port wrench. advantages and disadvantages of each if you don't mind. appreciate it.
Rear entry is by far the best since you can add a T bar and use pure torque without bending the action.
Tighter is better to avoid movement in threads.
For your rear entry wrench use one that has only lugs which mate at the front receiver ring. Avoid the plate style with the lugs engaging the whole receiver. Great tool to twist your action. Only want the torque at the front receiver ring.
