The Vortex Defender Flip Cap Eyepiece does exactly what it's supposed to do. It fits well, stays in place, and provides solid protection for my lenses in the field and at the range. The flip-up design is convenient and doesn't get in the way when shooting. Overall, it's a quality product from Vortex. It protected my lenses, and I really can't complain. Simple, effective, and reliable.

Must haves to pair with your Vortex scoped hunting rifles! Haven't tried them on other branded scopes, but they do have a great fit on my Vortex's, no surprise there! Flips out of the way when you need it to!

Just slips right on. I really like the sticker to put on the inside of the ocular scope end to keep track of the bullet drop hash mark. I always forget, but now it is there when you flip up the lid.

Scope caps are alright but same as some other reviews I have had the Hardeware fall out from recoil I was lucky enough to be over concrete and retrieve the spring, bolt and nut and locktite them back and it's happened again ,I'm searching for something that would not do that. .

These caps were perfect for my Vortex Scope. Fit was perfect and they will protect the glass on my scope while chasing Elk through the mountains of SW Colorado.

After trying several different covers, with no success, decided to order these. Covers are for a Vortex scope so figured they would fit. They fit perfectly! Covers are well made, open and close with no. problems. The material seems like it will last for a long time. Its a quality product from a company that Ive never had any problems with.

Have used in multiple matches now, fit is good and tight, and I like that when I open it, it flips open the whole way so it's fast.

They are nice and tight to apply. I don't think they are coming loose but I'm zip tying just for overkill. I like the addition of a dope card in the ocular cover. Because they are flexible material they will fit over the sunshade too.

This came with my strike eagle 1-8 ffp. As other reviewers stated, it simply does not stay on. It flips off when you try to flip it open, and it comes off when operating a milspec charging handle. I bought a charging handle with a large lever to solve the one problem, but the loose fit makes this only useful for storage. 2 handed operation is simply not acceptable. This is guaranteed to fall off during any kind of shooting sports. Unfortunately, the 1-8 ffp has such a large eye piece, its outside the size chart for butler creek. I will likely end up taping this on, to protect my glass during competition. As large as the eyepiece is, on my scope, I can't imagine this would stay on any of the vortex scopes.

Love the scopes, hate the flip up scope covers. I have two strike eagle scopes, both came with flip up scope covers and you have to use two hands to open them one to hold the scope cover on the scope and the other to open the cap. That is if they haven't just fallen off while you were walking through a field. Worst designed scope caps I have ever used.

The Vortex Defender scope caps are a must-have for any shooter. They keep your scope completely free of dust and rain, ensuring a clear view when it matters most. The tight fit gives you peace of mind-they stay put no matter the conditions. I love the two open positions, giving you flexibility depending on how you're using your rifle. Durable, reliable, and practical-these caps are worth every penny! Definitely an upgrade over Butler Creeks. I like them better than the more expensive Leupold metal caps as well.

I have set that has held up over 6yrs backcountry hunting so why not buy a set for all my scopes. Durable, lightweight, and protects!

The eye cap fits snug over the scope, and the vertical position is cool for referencing any data you put on the inside sticker. I used it on a FFP scope, but I imagine you may have some issues rotating the rear focus if that's all that's on your optic.

This is the last flip cap you will ever need! Virtually indestructible, this cap will fit snugly on nearly all Vortex Optics and features a snap flat spring that will keep your line of sight unobstructed.
Rifle ranges the world over are littered with broken flip caps. This is one cap you will most likely never see in a flip cap bone yard. The E-10 cap is has three stop positions. The first vertical, to put your dope disk (optional accessory) literally right in your face. The second at a 45 degree and the third at 90 degree to lay flat back.
The E-10 fits all Vortex Riflescopes except the 1" tube Viper model VPR-M-01BDC, VPR-M-04BDC and VPR-M-03BDC.
