Monstrum Rubberized Flip-Up Rifle Scope Lens Covers

It fit and good quality

Snug fit and easy to install. Great value

Picked a couple of these up for a Nikko Stirling GameKing. They fit well, and hold tight. I've since used them on several scopes and the flexible rubber makes them very versatile as far as fitment. The front bell on my scope was borderline between two sizes, so I ordered the larger one. I should have ordered the smaller size as it is just a tiny bit too big. That said, it still fits, because the rubber compresses and stretches.So far they close tightly. This might change with a lot of wear and tear, as they close via friction. To flip them you have to be deliberate, but it's not difficult. They are spring loaded, flip up positively, and stay in place once there.They look good, but the rubber does seem to hold onto dirt. I would get the FDE version if I could do it again, which I think would hide the dirt better.I did have some trouble with the position of the ocular cover as the bolt on my rifle knocks it open. My rifle is a Howa 1500 with a 90° bolt throw. If I had a rifle with a 60° bolt throw like a Thompson Center Compass I'm sure it would be fine. The Butler Creek covers have a similar setup and the same problem, so I don't consider this a deal breaker for the Monstrums. I just rotated the cover slightly which allowed it to clear the bolt. Additionally, the parallax adjustment on this scope is on the front, so the cover gets in the way. Again, not a big deal for me, but something to consider.Overall I enjoy these very much. They look good, and work well.

I was a bit skeptical about this flip-up cover fitting my 48mm scope, as it's right at the upper size limit. Surprisingly, it fit perfectly with a little coaxing. Once on, it's a champion—flipping open with Olympic gold-medal-worthy ease and snapping shut with satisfying authority. I'm impressed.

These rubber and plastic caps have a limited life span. They're all going to break or fail sometime, especially under real use beyond the range. These are good - great for the price. I like Monstrom's stuff for the most part. These small but important items can add up to big $. It's nice that a company like Monstrum seeks to produce affordable accessories. Because after all, how much does it cost to produce a bit of plastic and rubber? 10 bucks sounds right for this. And it is a quality item. It's snug and pops right open. Simple.

Excellent fit, closes tightly (and stays closed). FAR better than only slightly less expensive ButlerCreek.

Pros:affordableCons:- Sizing is funny, make sure you pay attention to the sizing part in the description, it's not your lens size. I'm not sure if that part was not there when I bought mine or if I missed it but mine was undersized for my scope.- The rubber that holds the cover looked old and dry- The rubber that holds the scop split into 2 like many people have shown in their reviews. Not sure if this was related to being slightly undersized as mentioned above but again, the quality of the rubber was not impressiveUltimately, I ended up buying another one of the correct size to give it another chance.

I have used another brands flip-up scope caps for a while now. I decided to try these new Monstrum Rubberized Flip-Up Rifle Scope Lens Covers and I am pleasantly surprised. For half the price, they are just as good. They seem nicely built. Only time is going to tell how these are going to hold up and I'll update you in a few months with what I think of them at that point. For now, I wish that both the eye cap and the lens cap had the same logo. Turns out, from reading other reviews that this is the case that both are different for some people. Not a big deal but just something I didn't expect. The eye cap doesn't have the two position stopping points like the Vortex eye cap but still works good. The Monstrum eye cap just flips all the way open. The rubber on each cap seems to be nice and is around the same thickness and size as the Vortex caps. Both of the flip-up scope caps go on tightly but not bad and are about the same as the Vortex. The caps seem to open nicely and they "click" closed nicely. They feel like they won't open up unless you want them open. The hinges and springs are nice and feel pretty heavy duty. I think they can take some bumps and still hold up. All in all, they are very nice for half the price of others flip-up scope caps. If I need more of these, I'll buy these Monstrum first if the ones I just bought and put on my scope hold up like I think they will. One last piece of advice, try not to stretch the rubber to much when you put them on the scope. I was able to get them started and then I just slightly twisted and pushed them on at the same time that I moved them in to position. Good luck and enjoy.

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

Seems to fit really tight and Nice. I like. Lol

Fait super bien sur le télescope de ma carabine.

It fits pretty good, only I've had it on my rifle for 2 months and the rubber sleeve has ripped right to the plastic making it unusable. I've been trying to get into contact with monstrum, but to no avail.
