I had my Black Diamond XR one afternoon after about 20 shots, slow down so much that you could watch the striker slide move. It finally got to where it would not cock. I never had the experience you and Roskoe had (thank goodness). My one other objection about the Black Diamond is when I field strip it to wipe the striker off and the striker slide area out, putting that locking nut back on with the rifle still all in tact can be a real.. [:@] Other then cleaning it, that rifle wil really shoot!
