For the past couple of weeks, I've had a Bushnell scope mounted on my VZ58. I have been trying to make my own shell deflector and attach it to the scope mount. The problem I ran into is that my VZ58 ejects the brass at the 12 o'clock position and at times, the deflected brass prevents the bolt from closing. The deflector is angled so that the brass deflects to the right. The last time I was at the range, I had 3 failures in 70 rounds i.e., the brass (really Wolf steel) goes in front of the bolt while the bolt is open, and prevents the bolt from closing. When I was at the range, another shooter commented 'that is a very unusual looking scope mount'.
