Don't trust volquartsen factory part assembly - Volquartsen Firearms Extended Bolt Handle and Recoil Rod Assembly for Ruger 10/22

I made the mistake of installing this part according to the instructional video, assuming that it had been assembled securely from the factory. It was not. After a number of rounds, the nut that captures the spring loosened, effectively increasing the length of the rod, and trapping it within the receiver. As it was jammed in place with no way to turn the nut for removal, I had to remove the barrel of the rifle to get it out. It caused some minor cosmetic damage to the interior of the receiver and pretty much ruined my brand new Volquartsen extractor. Once the rod had been removed, I tightened the spring capture nut and the rod fit accurately once again. The process was so aggravating that I really want to give the part a lower rating. However, it seems to be a great part. The problem was trusting Volquartsen to deliver it in ready to install condition.
