Monstrum Rubberized Flip-Up Rifle Scope Lens Covers

Awesome product and priced just right. Fits like a glove

Bought this to replace a broken lens cover hinge, and it fits like a glove; in fact it is better than the one replaced. Rubber sleeve adheres like a suction cup, and the plastic cap fits tightly over the cover to protect from moisture and dust. So good, I may order one for the eye piece.

Bought a set of these for my Leupold Freedom RDS (size 37-42). Nice snug waterproof fit. Clean snap of the rigid plastic cap when opening and closing. For the most part I liked it. It seemed like solid protection for my red dot at a good price. Unfortunately, both lens covers looked identical and I couldn't tell the difference (if there was one) between the eyepiece cover and the objective lens cover. When I put them on it made my big red dot look even more massive so, I gave one away to a buddy and kept this one on my objective lens (the objective lens on the Leupold RDS is 40mm). It lasted about a year before it split at the seams. The gun has only been used at the range and then stayed in my safe so, the lens cover hasn't been put through any challenging paces. Maybe I put the wrong cover on the wrong lens, who knows. It would be helpful if Monstrum would label the covers so one can know which cover goes to which lens. Still, I got a year of use out of it and for the price I guess I got my money's worth. I contacted Monstrum and they told me that they would replace it if I send it back to them. Their warranty is still good.

I like these. It gives you a little flexibility in objective sizes. Fits securely and latches well. I generally use Butler Creek caps but tried this one and really like it. Would recommend.

Perfect fit. Good quality.

Easy ro install and fits a variety of diameter scope bells. Does a good job of keeping dust and rain off your lenses.

Rubber split. Had this product for two seasons. This season the rubber that attaches to the scope split. I placed it back on and wrapped electrical tape around to try to keep it there. Came off walking through the woods. Should last longer than two season. Other than that, I feel like it is a good product.

I used a micrometer to measure the OD of my scope: objective=48mm, eyepiece=42mm so I ordered the 43-48 and 37-42 lens caps. There was no way I could fit the 43-48 cap on my 48mm objective! (Maybe if you clamped the rifle in a vice and applied some serious force or used lube.) Surprisingly, the 43-48 lens cap fit quite nicely on the 42mmm eyepiece with no chance of falling or getting knocked off. It was not too difficult to remove, which is a plus in my case since the variable power ring is on the very end of the eyepiece. So, if your scope diameter is close to the upper end of the specified range you might want to consider getting the next size up. One more minor quibble is that the cap seems a little too easy to open. The friction fit is controlled by tiny grooves on the ID of the lens cap, so if it's a problem I suppose you could add a tiny drop of glue or something to the OD of the flip-up lens cover. Even with the above caveats I consider this a a good lens cap for the price.

Fits 62.2 mm outside diameter objective bell on 56 mm Zeiss riflescope snugly.

Quite impressed with the quality of these, been shooting and hunting for fifty years+. The fit is great, tight and has considerable depth so you know its going to stay on the scope. I would definitely recommend to friends and family. Fair price for the quality!

Nice fit, works well.

What a PITA to install, but once installed it looks fine

These flip up lens covers are great. They ar Meade if food quality and the rubber sleeve is very flexible to get it on the Objective lens on your scope. I haven’t tried the eyepiece cover yet. I would suggest ordering slightly larger than what you think that you need. My first order was too tight and it would fit. I ordered the next size up and it fit perfectly. Highly recommended
