How were the threads on the RPR? Did the brake thread on easily by hand?
I have the same brake from ATRS. When I picked up my rifle at an Alberta dealer, a .308, I brought my brake with me and asked if they could throw it on for me. They had mentioned there was an issue with a customers 6.5, and a different brand brake, earlier that day. The guy at the store, who was a machinist by trade, took my brake and started to screw it on by hand, and it only did about a turn before it started to bind. He would not apply any force, as he said it should easily thread all the way on by hand. He had the same issue with the previous customers RPR, and already had a call into Ruger to see what they suggested.
The brake would easily install on a Ruger American model that he tested it on, and all the thread protectors exchanged between rifles. He felt there was a small tolerance issue with the threads on the rifle, and believed all it would take was a die to chase the threads, but was not willing to attempt this on my brand new rifle until he got a response from Ruger.
A week later, I'm still waiting for the dealer to get a reply from Ruger. He said my rifle my have to be sent to Ruger for warranty repair, but if Ruger was ok with him using a die to chase the threads, and I was ok with this, that would be the likely solution.
Was just wondering if anyone else has encountered tight threads?
The dealer did say that he had one customer install a brake on the RPR, but it took significant torque to get it on there. He didn't believe that forcing it was good, and once you do this, removal would likely be next to impossible.
