Review this product

Share your thoughts with other customers

Customers say

Customers praise the lens covers' rugged aluminum construction and excellent design, with one noting they don't look cheap like plastic caps. The covers fit perfectly, with one customer mentioning they're specifically designed for Leupold 350 Legend scopes, and are easy to install without special tools or knowledge. They work flawlessly with VX-1 3x9 40mm scopes, open and close smoothly, and operate quietly. While some customers find them worth the price, others consider them expensive.

Excellent covers, but Leupold front "L" emblem popped off 2nd time out
4 out of 5 stars
Excellent covers, but Leupold front "L" emblem popped off 2nd time out
I had these covers on a VX-1 before upgrading to the VX-2 4x12x40mm. They fit perfectly on both, and I highly recommend them. My only gripe is the front Leupold "L" emblem popped off the second time at the range because of poor quality glue. I'm using these on a Ruger Mini-14 Target (.223) so there is not a lot of recoil to begin with, but enough to pop the inlaid "L" off the front. Luckily I noticed when it when it popped off at the range, so I could retrieve it. I finally got around to securing it today with some JB Weld Kwik. Just make sure you scrape off all the factory glue first. Would definitely be 5-stars if they did a better job securing the emblems, especially for $100.

    These lens covers are the nicest I have ever seen. They are expensive, but are worth every penny. They operate completely silent and the covers flip all the way flat up against the scope. They have magnets on the inside that hold them shut and are threaded to fit onto your leupold scope. They also have an O-ring to seal they lenses from rain and dust. I was out shooting during a rainy day and opened up the covers to take a shot..........when I flipped the covers open, the lenses were completely dry. Plus once you thread them onto your scope, no more rotating like other covers I have had in the passed. I spent 1k on my scope, I can stretch the extra 75 bucks to protect it.

    Covers fit as advertised. Four star for not matte but gloss finish, don't match the scope.
  • Reviewed in the United States on October 19, 2023
    So far they seen good and worth what I paid for. They don't make a sound when flipping them up/open. Was worried their might be a sound that might spook a deer but they are silent. For the price it would be nice if they included O-rings on the threads for added protection. They are over priced for what they are made of and purpose, but then again I guess the added cost for piece of mind that they are going to fit your scope correctly and a warranty in case something ever happens to them sorta makes up for it. These should be sold for $50 as a more realistic price but the surcharge for leupold products makes them cost what they do.

    Very light weight, and love how there is no sound when they flip up. You don’t have to remove the scope to install the covers. Magnets work well holding them shut. I will buy more fire my Leupold scopes.

    Reviewed in Canada on October 30, 2015
    The single best upgrade you can make. Read about how to put these on because there are separate bearings that let you screw them on without taking off the scope.

    WAY cheaper in the US but was too big a pain in the ass so I just order them form Canada.
