## Description

This is the last flip cap you will ever need! Virtually indestructible, this cap will fit snugly on nearly all Vortex riflescopes 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 boneyard.

Review: Exactly What You’d Expect from Vortex - Really happy I picked these up. Vortex has always proven itself to me, and these flip caps are no different. Fit is solid, the spring action feels strong, and they snap open clean every time. You can tell they’re built to last and actually hold up to real use, not just sitting in a safe. I also like the multiple stop positions—it’s a small detail but makes a difference depending on your setup. At the end of the day, it’s exactly what you’d expect from Vortex: reliable, well-built, and backed by a warranty you can trust.
Review: Highly recommend - Great product with a reasonable price tgat fit perfectly

## Questions & Answers

**Q: I need the exact size for front & back to fit the scope?**
A: The number after the letter refers to the size of the objective lens. So the O-40 would work on anything with a 40mm, O-44 would be the 44mm etc... The Eyepiece should fit just about all eyepieces.

**Q: Will this fit on the eyepiece of a vortex viper pst 6x24x50?**
A: Mine does NOT.  It fits snugly over my 6-24x50 PST eyepiece, but the rubber runs into the first knob before it slides all the way on.  Worse yet, the cap simply will not stay closed, which negates the whole point of having a cap.  I will return this one and try a different cap.

**Q: What size caps would i need for a vortex viper pst gen II 1-6x24?**
A: According to vortex website sizes E-10 and O-24

**Q: Is this just one cap or for both ends**
A: This would be just one cap . Usually each end requires a different size.

### ⭐⭐⭐⭐⭐ Very tight fit but it's needed to keep rain and dirt out.
*by E***K on February 16, 2026*

Fits my Viper PST... Simple install though very tight fit, almost thought I wasn't going to be able to get it on but it kept the objective dry and clean like it should. Good quality as expected from Vortex.
