Very satisfied - Trijicon TX11 TriPower Medium Size Spacer for TX10 Flattop Adapter

Though on the expensive side the optic is definitely worth the money. Easy to acquire targets quickly. I did wish it came with flip cap covers and a better cover for the fiber optic but those have nothing to do with it's function. Overall I'm very satisfied with the optic.
Pros: Chevron is very clear point and shoot is very quick to acquire target.
Cons: Cover for the fiber optic coil I feel could have been better designed for the price off the optic.
