When I feel like letting go of $200 I'm going to pick up the Burris Fastfire.
It will be the topper to my Buckmark project. I already have the mount for it sitting on my work bench. Just need to pony up for the optic and the pic rail base for the optic. (fastfires have multiple mounting options. Unfortunately they are typically sold seperately.)
Fastfires usually come with the mount to fit a weaver/pic rail.
If yours doesnt, I have an extra one that I'd prob sell.
