This shows where I had to drill out the set screw for the LPR adjustment knob. Apparently it got cross threaded, and given it uses such a small allen key (.050), it easily rounded out the head. The only way to adjust the LPR was to remove that screw. I didn't have time to send it back to the company for repair, so I used a Dremel tool. You can see where the high speed bit jumped on me and left some scratches. This doesn't affect the function of the gun at all. I spoke with Dan at System X, and they said that they could replace the LPR cover, but I never got around to sending it in since it didn't affect how the gun worked. I just wanted to give you a close up view of this so you would know about it before hand.
