I've been shooting with Red Dot sights for a number of years so today I decided to put some fiber optics on my Black Mamba. I put a green fiber sight up front and a new adjustable rear sight. Once I had it sighted it I was very pleased with the new setup. That front sight is so bright that I had no trouble seeing it at the indoor range. It was easy to put the dot in the center of the 10 ring and to shoot it out. I even tried some real light ammo today to see how it would run. I shot some Wolf ME and they sure are light compared to my normal fodder but they grouped real well. Too bad they cost about $100 a brick now. I paid $40 years ago and still have a few bricks.
