Rated 4 out of 5 by Mrfixxit from A fix for very tight caps that pull off I bought the cap yesterday for my vortex long-range scope. And right out of the box the cap was too stiff to pop open and it would almost slide off. I contacted support but then I realized the reason was the Caps were way too stiff is because the little lip on the cap was too big. I took a flat knife and gently scratched at the edge of the cap and in the inside of the mating surface. Then I proceeded to polish inside in outside lip and the cap now opens very easily and doesn't pull off with good tactile feel yet. I know this isn't ideal for new product but sometimes you have to take matters into your own hands when quality control is not 99%.

Rated 2 out of 5 by jph4 from So close These are a little more expensive than other brands, but being made by Vortex, I thought they'd fill the bill. They are well built, for sure, but the fit leaves a bit to be desired. The eye piece cover fits perfectly and operates flawlessly. The objective cover is another story. The cap will slip off my Viper 4 - 16 x 44, so it takes two hands to operate, one hand to hold the cover in place and the other hand to open the cover. That's pretty inconvenient, in my mind. I ordered the size recommended by Vortex too, so I'm feeling slightly frustrated by this. I'm giving them two stars because they do a good job of protecting the lenses, but operating them takes some effort and precious time if you have a trophy lined up.

Rated 4 out of 5 by Caleb from Great — until they’re gone I bought an objective cap and an eye piece cap about a year ago and had zero issues until two days ago. On a cold, wet, mountain hunt the eye piece cap must have gotten moisture inside of the rubber and caused it to slide off somewhere between the top of the mountain and my truck. Extremely disappointed that this happened as the fit seemed to be tight and never had issues in dry conditions. This was my first hunt in any type of precipitation with this gun, so not sure if I could trust these caps going forward in inclement conditions.
