Diamondback® 3-9x40 Riflescope

The Diamondback® — loaded with features! First, the solid one-piece aircraft-grade aluminum alloy construction makes the Diamondback® riflescope virtually indestructible and highly resistant to magnum recoil. Argon purging puts waterproof and fogproof performance on the agenda, and advanced fully multi-coated optics raise an eyebrow when crystal clear, tack-sharp images appear in the crosshairs. Look for all this and more in a riflescope you'd expect to cost quite a bit more-but doesn't. We can live with that.

  • 3-9x40 riflescope is ideal for big game, muzzleloader, and slug shotgun applications.
  • V-Plex reticle is the single best all-purpose hunting reticle intended for a wide variety of hunting applications.

Subtension detail for the Diamondback 3-9x40 V-Plex Reticle. >

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 Great "working man" scope! I have deer hunted my whole life. I have used countless scopes by countless manufacturers. Between hunting and my job as a police officer there is not another brand i trust more than Vortex. I have a few different models specific to certain task but one of my favorites is my diamondback. For all around use it is great, clear, good in low light, durable and cost effective. A lot of folks cant afford to drop 1k$ on a scope and it sure is nice to have a scope and company that you can trust for a fraction of that price. Coming from a blue collar man that enjoys the outdoors, Vortex is who i trust.

Rated 4 out of 5 by from For inside of 300yrds this scope is great. Finally got to use the scope a few weeks ago zeroes great held zero without any issues. It was a pretty cold morning at the range and I never once had the lenses fog up. Now I'm looking into a longer range scope for a precision ar. And I will definitely be choosing vortex again. Dead hold redicle works great for my AR with .223 factory ammo just read the manual it gave me all the information I needed to calculate distance and how to use proper hold over. Only reason I'm at a 4 is I haven't got to use it any further then 250yrds. I will update when I get a chance

Rated 5 out of 5 by from Great Glass Better price This was my first scope purchase. I researched a lot and picked this for my deer hunting rifle. I was able to harvest my first deer and it worked perfectly especially for east coast ranges (0-300 yards) I also target shot sub MOA a couple of times and now moved it over to my plinking rifle in 22LR as I moved out west and needed to move up to the Diamondback HP in 4-16-42. Great compact easy to use riflescope. would get again or recommend. Also impressed my friends with MUCH more expensive glass at the range....

Rated 5 out of 5 by from Very good low budget scope I searched for a couple of months for a low power scope that would ft my needs. I have a similar Nikon scope. The Diamondback is cheaper. The reticle is more precise. Both scopes have BDC reticles. I prefer the Vortex. The viewing area around the reticle is more open and the reticle itself is less confusing when you trying to make those quick reference long distance shots. This scope is definitely worth more than the asking price. Vortex has set the bar high for scopes under 0 with the Diamondback.

Rated 4 out of 5 by from Best Entry level scope hands down I mounted this on my Marlin 17HMR. Originally I had a BSA Sweet 17 scope on it, but I am switching all my optics to Vortex. I really did enjoy my Sweet 17 scope, but the Diamondback scope's glass and construction are far superior than the BSA Scope. With the BSA scope I was knocking down prairie dogs at 100-200 yards, but with the Diamond back I am out to 300 yards. I have target shot with it at 500 yards and ringing 24" square steel. If you're on a tight budget this is the best scope you can get!

Rated 5 out of 5 by from Vortex is my optics I bot a dimondback for a rifle I got to last year to shoot coyotes with about 2 years ago and it has bin the best. This year my son that is 10 now wants to go hunting with me so I took him to the rage with my rifle and he was shooting great. So for his birthday I got him a ruger american compact in 234 topped off with a dimondback 3x9x40 and he is just waiting tI'll season comes to kill him 1st deer .I can't wait to be there in the blind to see him take one down. Vortex will be my optics for life ..

Rated 5 out of 5 by from I would put this scope on every rifle I own. Great scope at a great price. I have 2 of these scopes. One is mounted on a Ruger 30-06 and the other is on a Remington.270 wsm. These scopes hold zero very well and the adjustments are precise. I have zeroed the scope on the .270 weight for 3 different shooters with ease and no loss of performance from the scope. Both scopes have been bumped or banged around multiple times and have completely held zero. Clarity in low light is terrific. I can't find anything to complain about on these scopes.
