Rated 5 out of 5 by Kristopher from Awesome Quality! I have owned and throughly abused my diamondback 3-9x40 for about 4 years; its been rained on countless times, dropped as a result of sling malfunctions, its been frozen solid in -30(-22F), and even covered in mud from being strapped onto ATV's. I am thoroughly impressed. The glass on my diamondback is clear as day, the magnification ring is smooth, and aside from exterior scratches and scuffs the scope has held up wonderfully and is always bang on when it counts. Being a student this scope was at the top of my price range but DEFINITELY worth every dime. I have nothing but good to say about it. Vortex has gained a costumer for life.

Rated 5 out of 5 by KY Keith from An Awesome Scope At An Awesome Price! The Diamondback series of optics is what got me hooked on Vortex. It started with the binos and led to scopes. My 3-9x40 with v-plex reticle is currently on my muzzleloader. This scope has withstood the recoil as well as being bumped and knocked around a little in the deer woods. The clarity of glass is excellent in this price point and even better than some above. The Diamondback is a basic no frills scope that just does what it needs to do. It's clear, holds zero, has positive/repeatable adjustments, and it can take some abuse. If you want a riflescope that you can rely on for your hunt without breaking the bank then the Diamondback is your answer.

Rated 5 out of 5 by LeRoy from great scope, great price, and yes I own a couple The scope holds up beautifully to heavy recoil. It's clear with easy target acquisition. I recommend that you use the Vortex site to input your load information for your BDC, it'll give you a good idea of the ranges for your BDC. The Vortex warranty is the best on the market. I had smoke damage to a couple scopes, called them up, sent the scopes in, and not only did they replace the scopes but the package came with a couple t-shirts and hand written note. The folks at Vortex went above and beyond with their customer service. They make excellent products and their customer service is the best in the business.
