Rated 5 out of 5 by from Vortex Defender scope flip caps In my experience with Vortex products... difficult to put into words how impressed I am with so many facets of this company, the products are cutting edge, intuitive, aesthetically pleasing, customer service is out of sight. All my delivery times of been fast and problem free. The warrantees are solid and without question. My personal experience with decades in special operations, military acquisitions and law enforcement give me unique perspective on equipment and procurement. My recent purchase of the defender flip up caps shows me the incredible development skills of this company… 100% satisfied on all levels

Rated 5 out of 5 by from Excellent features that work. I received my caps a few weeks ago. I have used them on the range in sub-freezing weather and at a Long Range match with high winds kicking up lots of fine dust. These caps kept the image through my Vortex PST crystal clear without a ton of dust distorting my view. I like the fact that the cap has tabs on each side that can be used to flip it up. The springs used in this cap are great this thing flys up and out of the way. The rubber part grips my sun shade tightly and does not move. Even in the cold weather the caps are not brittle and stay flexible. Once again Vortex has put out a great product!!

Rated 1 out of 5 by from Completely fail under cold and damp conditions The tension / adhesion that holds these covers fails completely under cold and wet conditions. In approximately 20 degree snowy weather this 3rd rifle season here in Colorado (the type of weather you might want to have a scope cover for), both this and the smaller objective cap slipped off multiple times during the course of a single hunt. Attempting to deploy the flipping action often removed the scope cover from the scope. Having a piece of equipment fail multiple times during the course of closing on a deer was an unnecessary distraction and could have ruined the opportunity. The larger objective also slipped off and was lost in the long hike back carrying the quartered deer. If you are hunting in potentially cold and damp / snow conditions look elsewhere, these caps are a hinderance rather then an assistance.

Rated 4 out of 5 by from Very Very Close to Perfect. I love how the 50mm fit's onto my PST, however when opening the objective end it sometimes moves around. This has never caused an issue, but is something to watch for.

Rated 4 out of 5 by from Great Coverz Put these on my PST 6-24X50 and they work great. They do move a little under use , otherwise they would've gotten 5 stars.

Rated 5 out of 5 by from Great Objective Lense Cover I have tried this lens cap both on an doff the range. The objective cap is awesome it grips the sun shade and objective end of the scope very well. It provides a tight fit with little to no movement. The rubber is a great design for this end however, not as good on the eye piece which I will explain in a review on the eye piece cap. Other than that it is amazing great spring tension and the ambidextrous tab feature is a must! These are mounted to a Vortex Viper PST 6-24 FFP.

Rated 5 out of 5 by from Great, durable, tighter fit Great objective cap. Spring tension is there, the fit is tighter than most previous covers have been (and many complained about) and it appears Vortex is yet again going above and beyond to address and modify it's products based on its customers views.

Rated 5 out of 5 by from Awesome accessory for any scope. I've used a different companies scope caps for years and decided to try the new Defender caps. I'm glad I did. I don't have to worry about them popping open during transporting my rifle and they're built solidly. Highly recommend this for anyone.

I am purchasing a Crossfire II 6x24x50 AO, what cover do I need for the eye piece as well as the objective? are they sold as a set? and will it work with the sunshade the optic comes with?

Asked by: Scottie V.
Thanks for the question! The Defender Flip Caps are not sold as a set. You will need the E-10 eyepiece and the O-56 objective piece. Due to the AO (Adjustable Objective) you will need to go with the larger size objective cover. However, for the sunshade you will need to go with the O-50.

Will the 0-50 cap fit the diamondback tactical 6-24x50? Thanks 

Asked by: Daniel83
Thanks for the question! Yes, the O-50 will work for the objective side. If you needed the eyepiece as well, you will want the E-10.

I have a Vortex Viper PST Gen 2, 5 to 25 x 50. Need to know what size lens covers to order? 50 for the objective makes sense but what do I need for the front lens of the scope?

Asked by: Tyson
Thanks for the question! Yes, you will want the O-50 for the objective side and the E-10 eyepiece for your eyepiece.

I have the VIPER PST 6-24x50. I am using the standard defender E-10, but have trouble keeping the eyepiece mounted with the battery dial for the lit reticle as the rubber section bunches up around the dial. Is there a solution for this?

Asked by: Nick
The E-10 should not run into the illumination dial unless you are pushing it on too far, the hard plastic of the flip cover should not go past the rubber ring on the end of the eyepiece.
