Product delivered timely and at a great price. Fit and finish and function as expected based on the description.

It's basically got a rubberized tube, so it can stretch onto tubes of different sizes. You can yank it on, to where the harder portion of the flip cap is flush to the end of the scope tube. It works well. Then it's just a simply plastic flip cap. My scope is mounted such that there are 10mm or less between the front tube body and the rail, and it still fits well and flips easily. I'm disappointed that Vortex doesn't make something better. The interior of the front shade tube is threaded. I'm running a Vortex 3-18x50. When someone is running a scope that costs more than $1,500, you would think Vortex would come up with something that threaded into to the shade tube and was metal. I also have Luepold scope, and really like their scope flip cap. But overall, it works.

I needed some scope covers for my Athlon Midas scope and these were the best option available. I'm very happy with how well they fit on my scope and the flip up features work perfectly. I would definitely install these again on my next rifle.

They're superior lens caps. They kick the shit out of butler creek but the latch fades compared to Tenebrex. However...the rubber sleeve attachment system, while basic and cavemanish...is rock solid. It won't move for anything once the rubber is snugged. Make sure you don't cant your cap. I'm likely to buy these for another scope simply because they'll fit, stay on and stay closed.

This is a superior, more durable product than the B.C. competition. Not brittle or prone to breakage, quieter in operation, no wee small parts to fail.
