I just customized two new 10/22's and am experiencing a new problem. I installed a volquartsen target hammer/springs utilizing the required bushings, and now the safety mechanism on both rifles frequently (almost always) sticks when trying to switch it to the "Safe" position. If I continue to fiddle with it, without changing anything else, they will eventually move all the way to the safe position. I hope someone has some good advice, these rifles are definatley not leaving the shop until the problem is resolved.
