When I was physically able to shoot service rifle matches, I had a similar problem with the sights on my AR15A2 Service Rifle. My options were limited by NRA/CMP rules. I used a National Match front sight post, and I replaced the rear sight "L" with a threaded "L" that had interchangeable inserts to vary the opening of the rear sight aperture. Sometimes, I had to change inserts depending on the light. To increase contrast between the front sight and the rear sight, I would use my carbide lamp to darken the front sight. If you don't want to dabble with a carbide lamp, G96 use to make an aerosol can of sight black that worked.

As an aside, with this method, I was able to earn my Master classification (consistent 94%+ match average) shooting position matches out to 600 yards. I never fired a match on a reduced course of fire. If I remember correctly, the rear sight that I used was marketed bu Armalite.
