  • Battery: CR2032
  • Click Adjustment: 0.25 MOA/Click,
  • Turret Style: Tactical

Why pick the Vudu 5-25X50 scope - The VUDU 5-25X50 is a compact first focal plane riflescope with the shortest overall length on the market today, and it's perfect for a DMR style AR10 rifle.

Saves Rail Space For Addon Scope Accessories - The user can mount thermal and night vision scope addon in front of the Vudu on AR10 rail system with plenty of space thanks to the shortened scope length.

If after dark hunting is more your style, the AR-10 has become insanely popular for hogs and coyotes, especially when paired with a night vision or thermal optic.

On the downside, shorter optics makes finding the right eye-relief difficult. It can slide extended optics further back or forward.

Generous Eye Relief - At VUDUs lowest magnification setting, eye-relief is a generous 3.71 inches; the highest magnification setting is almost identical at 3.63 inches.

More Head Movement - A larger exit pupil means the position of the shooter’s head is less critical. Consider this when selecting the right scope; eye relief on a standard scope is about four inches. Greater eye relief offers more room for recoil.

Why use red dot & magnifier while you can use a low power variable optic - If you want to set up a low drag AR10 as a personal defense rifle and also capable of mid-range shooting, then a red dot & magnifier combo is the best choice for saving weight & keeps your rifle looking slick.

AR10 Scope Buyer Guide For 308 Ballistics

Effective AR-10 Ranges [308]

The most popular AR10s are chambered in 308, so this guide will focus on that. If you have a AR10 chambered in 6.5 Creedmoor, please check out this scope guide.

You can also pick a scope based on the distance you can shoot with an AR10

  • Close Range: <200 yards
  • Medium Range: Between 200 to 400 yards
  • Long Range: 400+ yards

CLOSE RANGE (>200 YARDS)

Truth is, the AR-10 isn’t a close-range weapon, but you can if you want to for hunting and personal defense. A low power variable optic will be best suited for this.

  • Magnification: 1 – 4X power

MEDIUM RANGE (200 – 400 YARDS)

This is the most common shooting distance for the AR-10 on a flat range or for hunting.

  • Magnification: Between 5 – 9X power 

LONG RANGE (400+ YARDS)

This is the range a 308 chambered AR-10 excels in. In fact, some people have used AR-10s to beat bolt action rifles in sharpshooting tournaments.

  • Magnification: 9X and up

Should You Pick A Caliber Rated BDC Reticle or A Christmas Tree Reticle?

A 308 rated Bullet Drop Compensator reticle is great for hunting & provides quick hold over for fast shooting, but not recommended for precision shooting up to 600 - 1000 yards or more. Instead a Christmas Tree style MOA or Mil grid reticle is recommended.

We highly recommend the Horus H59 or the Horus Tremor 3 reticle. As soon as you understand how to use them, shooting becomes super easy.

Why? 

Please note that a calibrated BDC reticle is only good for the specific rifle platform the factory has calibrated for. 

But...

As soon as you mount the scope on a slightly different rifle with a different barrel twist rate or barrel length... not to mention a different type of bullet, then the BDC line will not match the ballistics.

Therefore you can't just mount a BDC reticle scope randomly and expected it to be accurate on a rifle you have not tested.

Recommended Scope Rings & Mount

There are plenty of scope mounting systems out there. 30mm and 34mm scope mounts are the most popular.

Since we are mounting the scope on an AR10, we highly recommend using an one piece scope mount that allows for precise alignment without scope lapping, and provides high confidence zero retention if the scope is mounted & taken off constantly.

We recommend scope mounts from:

  • Geissele Super Precision Mount
  • LaRue Tactical QD Scope Mount
  • American Defense
  • MDT Scope Mount
  • Sphur
