The Black Aces rail is high enough so you can still see the front sight under the rail. The laser is aligned with the front sight. The red laser on my MP 340 revolver was not visible at all, but the green works well.

I put the Crimson Trace CMR-206 on mine. I had it sitting in my safe. I put the Black Aces rail/side saddle and put the laser near the muzzle. I really like it.
I tried again and could see the laser out about 100ft out on an old oak tree, but it gets a little tough trying to see it. But for my purposes, 7 yards inside my house is the maximum I need.
I am new here but was just playing with the CMR-206 today. I could see it on the side of my shed about 50 feet away and even pointed at a big oak tree about 70 ft out but it was hard to see. That is daytime with sun and snow on the ground.
