.308 Scope Selection Guide

Find the Best Scope for Your AR-10 and 308 AR Rifle

There used to be a guideline to budget as much on your rifle scope and scope mount as you spend on your rifle, while that still applies somewhat today if you want the best scope money can buy and have the cash to buy it but you shouldn’t feel pressured to do so.

Define Your Scope Needs and Budget

From a budget and magnification standpoint be realistic with your needs. You don’t need a $4300  NIGHTFORCE BEAST 5-25X56MM SCOPE ZEROSTOP F1 DIGILLUM H59 RETICLE to punch paper at 100 yards or hunt wild boar in the brush. On the opposite side of the spectrum a $250 VORTEX OPTICS 4X CROSSFIRE II isn’t going to be your best choice for taking out bad guys at 800 yards.

You Get What You Pay For With Scopes

Modern manufacturing methods have come a long way to improve the quality of low cost scopes but make no mistake there are substantial differences in most expensive scopes.

  1. Construction Quality: Generally speaking expensive scopes are precisely manufactured optical devices inside and out
  2. Glass: Expensive scopes typically have better glass that is clearer and brighter than cheap scopes. They also feature coatings to improve optical performance.
  3. Light Gathering
  4. Useable Magnification:
  5. Precise Adjustments:

  7. Environmental Resistance:

Brownells Match Precision Optics MPO Scopes

Brownells Match Precision Optics MPO Scopes

Made with high-quality Japanese glass, MPO scopes from Brownells have an illuminated non-obscuring milling reticle etched onto the first focal plane. This reticle allows the shooter to easily center the target at high magnification, while still having a strong crosshair aiming point at low magnification.

In addition, Brownells MPO scopes are full of other features long-range shooters and competitors look for, but at very competitive prices.

Turrets: The MPO turrets feature 10 MRAD per turn adjustments in 0.1 MRAD increments. The elevation turret has a resettable zero with built in zero stop, a feature we feel is necessary for competition use and helps prevent the shooter from getting “lost in the turrets”. The windage turret is capped to prevent accidental adjustment and give added protection to the turret so competitors can remain confident in their zero while maneuvering obstacles while on the clock. Both Turrets feature a helical version of our Glock slide serrations to ensure a solid grip even with wet hands.

Maintube/Magnification: The 34mm main tube allows for maximum adjustment range with the internal optic system. The MPO 3-18x50mm features 40 MRAD of internal adjustment and the MPO 5-25x56mm has a total of 20 MRAD internal adjustment. The built in magnification lever gives the shooter a solid purchase on the mag ring and helps increase leverage to make mag changes on the clock nearly effortless.

Components/glass: All MPO scopes feature edge blackened glass, the less stray light bouncing within the optic, the better the image quality. Multicoated lenses help improve light transmission while also protecting the lens surface from scratches. Before the optics are sealed up, they are Argon purged to ensure the internal lenses are fogproof.

Includes: Both models include a 4″ sunshade, lens caps, cleaning cloth, and tools needed to adjust the turret.

Vortex Diamondback Tactical 4-16×44 FFP Rifle Scope

Housed inside its durable, one-piece aluminum tube is a 4x optical system delivering excellent edge-to-edge clarity and sharp resolution. Exposed elevation and windage turrets are low profile enough to stay out of the way in packing situations, but offer the quickness, ease and precision of dialing accurate shots at distance. A side adjustable parallax gives shooters peace of mind by removing parallax error from the equation from 20 yards to infinity.

NIKON BLACK X1000 6x14x50SF 308 SCOPE

NIKON BLACK X1000 6x14x50SF 308 SCOPE

The NIKON BLACK X1000 6x14x50SF is part of a new line of mid-level priced Nikon riflescopes geared towards AR-15, 308 AR and Precision Rifle Shooters. When I saw the Nikon M-308 series 308 AR scopes going out of stock at the usual big name sources I had a suspicion there were new Nikon scopes on the horizon. The scope market is very competitive especially in the $399-$699 price range so it’s no big surprise I was right. Recently the Nikon Black X1000 Riflescopes became available for purchase. Nikon appears to be marketing their Black1000 scopes and Nikon Black scope mounts towards the “MSR” rifle shooter. The Nikon Black X1000 appear to be priced about $150 less expensive than the Vortex PST Gen II. This is a smart move in my opinion. Nikon also seems to be touting their warranty. Again Nikon is clearly targeting Vortex. These new Nikon scopes should be well received by 308 AR, AR-10 and AR308 shooters looking for affordable scopes.
