Note: Optical sights are NOT an option as the point is to beat the scope and red dot guys with just my plain old eyeballs.
Note 2: Part of the problem is that I'm competing with black rear (factory) sights, black front (factory) sight, against black 2" clay pigeon targets against a black background. The devil-inspired match director will also do such nefarious things as paint the clothespins that hold the clay pigeons to the chicken wire black, and paint the wire itself black.

Question 1: I've looked at the VQ rear sight for the Mark II. It looks just like the factory rear target sight I already have. What, if any, is the difference and advantage?
Question 2: With the factory rear sight blade and front sight, there is a fair amount of space to be equalized on either side of the front sight as I align it in the rear blade notch. Are there narrower rear sight blades available? (Can't find any)
3. I've tried painting the front sight blade with Brite-Sights paint, but the result is disappointing, at least partly due to the 'reverse' cut of the front sight - it doesn't really reflect light very well.
4. How about fiber optic for the front sight? Problem is, I can't find anything for the MK II Target with tapered barrel.
5. Any other suggestions for front and/or rear sights? I need good contrast against a black target against a black background, as well as precision and quick alignment.
I've been toying with getting some extra front sight blades and trying some Bubba engineering to get a fiber optic light pipe in there somehow.
Suggestions?
Thanks in advance.
