After having some unexplainable jams with my Ruger 22/45 / Black Mamba during my last Steel Challenge Match I tried everything I could but never did get it to run 100%. Stumped, I called Volquartsen for help. They told me to send it in so that they could check it out. A simple fix, the Guide Rod was bent. Now that it's back with a new GR everything is working well and I'm set to go for October's Arizona State Steel Challenge Championship.
