Rated 5 out of 5 by 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 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 from Diamondback 3-9x40 what a great scope! I recently came across a diamondback 3-9. And went a head and pulled the trigger on it. I am so glad I did because after sighting it in and shooting with the optic what an amazing scope the quality is there and for the price what a deal! I have no complaints about the scope and the quality of it. It by far has amazed me. I for now on will always go to vortex. I only wish I would have gotten vortex before my other optics because what a difference on many levels. If you are concerned about the diamondback 3-9x40 have no worries it is so worth it! I can only imagine how vortex’s higher class scopes are.
