Get the Burris FF3 if you want high quality for a reasonable price. Don't have a Buckmark, but if I had one, I'd put this sight on it. Low profile/ Fast aquisition of targets!
it has 4 settings for brightness and holds POI for thousands of rounds.
Haven't needed to fiddle with it since I set it the first time about 6 months ago. Probably put a few thousand rounds through it with the FF3.
i think they all come with a picattiny adapter, but I'm thinking about ordering MK adapter for mine soon.
