Features

  • Rubberized flip-up rifle scope lens covers that conform tightly around your rifle scope tube, protecting your lenses from dust and abrasion
  • IMPORTANT: Sizing is not based on the objective lens size of your scope - a 3-9x40mm scope will not fit with a 40mm sized lens cover. For the correct fitting lens cover, you must physically measure the outside diameter of your scope eyepiece and objective.
  • Each package includes one Rubberized Flip-Up Lens Cover
  • Spring-loaded flip-up mechanism pops open effortlessly when needed and securely tightly when not in use
  • Please refer to sizing chart and sizing video, carefully measuring the OUTSIDE diameter of your scope, to ensure the proper size and fit.

  • Flip up scope lens cover
Size: Objective Lens | 43-48 mm diameter
The fit is excellent, product seems to be constructed of quality material, price is economical & the functionality of the product works as expected. I cannot rate on the durability yet as I’ve only had them a short while.

  • Caps do fit well and work well
Size: Eyepiece | 43-48 mm diameter
Caps were deflated in packaging , have to be slightly heated to mount on scope , possible some type of packing inside of scope cap to fit . To prevent crushing of rubber.

  • Bulky but nice
Size: Objective Lens | 37-42 mm diameter
Pretty good for the price, I installed them on a Burris Scout Scope 39 objective 38 ocular and they fit snugly. My Springfield Scout rifle has Warne Rings low. The eye piece cover will not allow complete rotation of the eye piece because the hinge portion of the cover hits the receiver. Good covers and I will hold onto them for use on a different platform. ... show more

  • Happy with purchase
Size: Objective Lens | 43-48 mm diameter
Flip up scope cover fit over my Nikon scope front lense perfectly. Because there is an adjustment wheel it will be more difficult to change the setting but this is because of the scope and not the cover. Cover was inexpensive but seems to be sturdy. Flipping up the cover is easy and quiet.

  • Easy to install. Flips open well. Stays secure.
Size: Eyepiece | 37-42 mm diameter
The media could not be loaded. I bought this for my crossbow scope. I love the quality of the build. Everything is precise and the hinge is tight and smooth. I love how easy it is to install. It’s quiet to open and close. A little pop when opening and closing, but as a hunter I know it’s not loud enough to be an issue. Another bonus is it’s ambidextrous. Other scope covers have a release on one side. The design of this scope cover works regardless of which side you choose to touch. I’m going to buy these for every scope I own. ... show more

  • affordable but cheap, careful with sizing
Size: Objective Lens | 49-54 mm diameter
Pros: affordable Cons: - 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 impressive Ultimately, I ended up buying another one of the correct size to give it another chance. ... show more
