## Description

desertcart.com : Arken Optics Rifle Scope Caps Flip Up Lens Covers 37-42mm&46-54mm : Sports & Outdoors

Review: MUST HAVE - The build quality of the rubber is very excellent and elastic. The finish is very good and fits very tightly. The flip-up cover spring is very good and the cover for the front flips all the way back up to 45 degrees , wile the cover on the back when it flips up to 90 degrees and I had to make a minor adjustment with the dremmel tool so it can go back further to 45 degrees making room for my hat. Overall works very good and will not come off unless you use a bit of force. Worth the money.
Review: Perfect Fit - Perfect for my Arken EPL-4 scope. Easy to take on and off and seem to be durable. This company is quickly becoming a go to for my optics. Great value, lightweight and not bulky.
