Vortex Diamondback 4-12x40 Matte Riflescopes Product Info

Vortex Diamondback 4-12x40 Matte Riflescope delivers all of the power you need for medium to long range hunting. Vortex Diamondback Rifle Scopes' pop-up dials provide easy, precise adjustment of elevation and windage, making audible clicks easily and quickly counted. Vortex knows good hunting gets all the better with high quality optics. The Diamondback 4-12x 40mm Matte Rifle Scope by Vortex consists of a rugged, durable 1" tube constructed of 6061 T6 aircraft-grade aluminum. Vortex Rifle Scopes subject all of their riflescopes to demanding factory testing under a force of 1000 G's - 500 times! Not only is this rifle scope waterproof and fogproof, it is highly prized for its purging with Argon gas, targeting corrosion in an unchallenged way. This feature helps to eliminate internal fogging, chemically ignoring water. Like the Vortex Viper Riflescopes, you can count on the Vortex Diamondback 4-12x40 Matte Riflescope for smooth handling when the heat is on.

The Vortex Diamondback Riflescopes are also available in 1.75-5x32, 2-7x35, 3-9x40, and 3.5-10x50 models.

Helpful Negative Review NOT a high quality scope. by Koot1971, December 22, 2014
Poor eye relief, Not a very clear scope, especially in low light. I Have the same scope in 3x9 W/O BDC reticle and it works great. I'm not real sure if I got a lemon or what,so I returned this scope.I'm not sure what scope I'll buy next.

Most Recent Review Vortex 4-12x40 BDC scope by Bob, March 28, 2015
I own many scopes by big name manufacturers. I put this scope on a 7mm-08 for one of my adult daughters. The glass is as bright as any of the best with clarity all the way out to the edges. The back optic adjusted easily to my old eyes allowing a sha...
Most Recent Review Rivals Leupold VX III in Brightness and Clarity by Terry, January 28, 2015
Before ordering the Vortex Diamond Back 4-12x40 I ordered a Nikon Pro Staff 4-12x40. I was not happy with the Nikon due to a very small field of view as well as a much greater length and added weight. While researching the scopes in my price range(Re...
