Fair fit and function on a Bushnell Trophy. I wouldn't protect a scope worth more than $100 with them. These had raised lips to snap into a ring groove for both ends, however my scope only had a groove on the eye cup side. So, the base ring sits cocked on a smooth bore end and doesn't look very pro. However, they fit well on the grooved end, they're snug on both ends should keep out the elements. I'll probably buy something else eventually, however, they'll do for now.
Got these for my Bushnell TRS. After gluing them on to the ends they work great. Am really happy with these and will buy another set for my other TRS. Worth the money.
