The Best Scope for 308 Shooting: Getting Long Range Hits

Our winning .308 scope is up first. The contenders will be presented in order of price, from least expensive to most outlandishly priced.

Let’s get snapped in.

1. Vortex Optics Crossfire II 4-12x50 AO Second Focal Plane Riflescope - Best overall scope for 308

The Vortex Crossfire II 4-12x50 AO Second Focal Plane Riflescope is a budget Vortex 308 scope. But, even if it is a budget scope, it’s still a solid optic.

4-12x is a versatile magnification range. This scope could easily be mounted on a hunting rifle or a competition rifle.

Additionally, the 50mm objective lens and full multi-coated lenses produce an exceptionally clear, high-fidelity image. The light transmission makes it easy to spot animals at dawn and dusk, or spot your shots even when the target is shaded.

The parallax is adjustable, for maximum reticle stability at any range and magnification setting.

This scope is equipped with Vortex’s Dead-Hold BDC Reticle, which gives you several aiming points for Kentucky windage and holdovers. The reticle helps you make quick shots at varying ranges without adjusting your scope.

Sadly, this is a second focal plane scope. The reticle doesn’t retain its proportions through each magnification setting. So, you’ll need specific calculations for each magnification setting.

Even with that bit of extra work, this scope is still a perfect option for anyone who wants a solid hunting or competition scope that won’t drain their bank account.

Pros

  • Versatile magnification range.
  • Large objective lens and full multi-coated lenses produce a bright, clear image in most light conditions.
  • Adjustable parallax for parallax-free performance at all ranges.

Cons

  • Second focal plane requires a few more shooting calculations.

2. Nikon P-Tactical .308 4-12x40 Matte BDC800 - Value Scope for 308

The Nikon P-Tactical .308 4-12x40 Matte BDC800 replaced the beloved Nikon P-308 scope. However, it’s almost the same as the P-308, but with a few upgrades.

This scope is fitted with a 4-12x magnification range for versatility. The 40mm objective lens and Nikon’s full multi-coatings transmit 98% of the collected light to your eye. So, you’ll get a clear, high-contrast image at any magnification setting, in all light conditions.

Unfortunately, the parallax isn’t adjustable. You’ll need to account for the parallax at some ranges.

But, the Nikon BDC800 reticle offers aiming points that are specifically calibrated for the .308 round. The aiming points are spaced in 100-yard increments out to 800 yards. The reticle makes it easy to shoot with an overhold for faster shots at varying ranges.

Also, this is a first focal plane scope.

So, your shot calculations will be accurate at all magnifications.

This isn’t the least expensive scope on the market. But, it’s an incredibly capable optic that’s suitable for hunting any type of animal and taking shots from the competition bench.

Pros

  • Versatile magnification range.
  • Excellent light transmission for solid low-light performance.
  • Reticle has aiming points for holdovers out to 800 yards.
  • First focal plane retains reticle proportions at all magnifications.

Cons

  • Parallax is not adjustable.

3. Vortex Optics Diamondback 4-16x44 First Focal Plane Riflescope - Tactical Scope for 308

The Vortex Optics Diamondback 4-16x44 First Focal Plane Riflescope is designed for the quick operation and long range capabilities that tactical shooters need.

First, the 4-16x magnification is low enough to scan and acquire targets, but powerful to engage at maximum range.

And, this is a first focal plane scope. So, you can quickly transition between magnification settings with the same elevation settings.

Additionally, the EBR-2C reticle has elevation lines for holdovers, and hash marks for windage estimationThe reticle is excellent for making quick range and windage estimations, and taking quick shots without adjusting your optic.

Lastly, the parallax is adjustable for parallax free aiming at all distances.

44mm objective lens and Vortex’s proprietary lens multi-coatings maximize light transmission. You’ll get a bright, high contrast image even in low light and inconsistent lighting.

For tactical shooting, an illuminated reticle would make this scope perfect. The reticle is etched, which makes it crisp. But, it can take some effort to find your reticle against dark backgrounds.

But, this scope will deliver excellent clarity and accuracy for the vast majority of shooting situations.

Pros

  • Wide magnification range for tactical shooting.
  • eticle has excellent markings to assist with estimations and calculations.
  • Adjustable parallax.
  • First focal plane maintains reticle proportions at all magnification settings.
  • Outstanding light transmission and image clarity.

Cons

  • No reticle illumination.

4. Nikon M-Tactical .308 4-16x42SF Matte BDC800 - All-Purpose Scope for 308

The Nikon M-Tactical .308 4-16x42SF Matte BDC800 is Nikon’s update to the venerable Nikon M-308 scope. The specs are very similar. But, Nikon made a few upgrades.

Nikon fitted this scope with a 4-16x magnification range. It’s a good all-purpose magnification range.

Typical deer hunting scopes are 3-9x. Tactical and competition scopes usually push a bit higher, with something like 6-18x or 6-20x. As you can see, this scope sits in a nice middle-ground between hunting and long-range precision scopes.

Additionally, Nikon uses professional photography grade lens multi-coatings. They paired the high clarity lenses with a 42mm objective lens to collect lots of light. 

These two features enable this scope to produce a bright and sharp image at all magnifications, even in dawn and dusk conditions.

Nikon also equipped this scope with the Nikon BDC800 reticle, which gives you bullet drop marks for over holds all the way out to 800 yardsIt makes it quick and easy to take shots at varying distances.

The only real shortfall of this scope is that it’s a second focal plane scope. So, you’ll need to make a range card for each magnification level.

But, Nikon offers software for building range cardsWhich makes this scope a great optic for anyone who wants a one-size-fits-all scope for multiple types of long-range shooting.

One last thing: if you want a similar scope with an illuminated reticle for better low light performance, get the Nikon Black X1000 4-16x50SF Matte IL scope.

Pros

  • Versatile magnification range.
  • Super clear glass with photography-grade multi-coatings.
  • Reticle has bullet drop marks for over holds.

Cons

  • Second focal plane requires specific calculations for each magnification levels.

5. Trijicon ACOG 3.5x35 Riflescope - Scope for .308 AR

The Trijicon ACOG 3.5x35 Riflescope is designed specifically for tactical battle rifles like AR-10s. The idea is a scope that’s capable of semi long-range shooting, but that’s not too cumbersome for short-range tactical operation.

The magnification is set at 3.5x. It’s enough that you’ll be able to reach out a bit further with the .308 round. But, you can still run and gun with both eyes open, and use the aiming point for CQB shooting.

There are two aspects of light collection on this scope: the objective lens and the fiber optic light collector.

Trijicon uses extremely clear glass. And, the 35mm objective lens collects plenty of light for producing a high-contrast image at 3.5x magnification, in most lighting conditions.

Then, the fiber optic collector gathers light to illuminate the reticle. This offers batteryless reticle illumination. The reticle is super bright and crisp.

And, the reticle has bullet drop hash marks for using hold overs out to 800 meters.

However, in full sunlight, the reticle can be a bit overpowering. But, you can partially cover the fiber optic light collector to reduce the brightness.

This is one of the premiere combat-proven optics on the market. It’s an incredibly functional and durable optic for an AR-10 or any other .308 battle rifle.

Pros

  • Battle-proven durability and function.
  • Handy magnification power that’s good for both short and long-range shooting.
  • Excellent image quality.
  • Batteryless reticle illumination.
  • Bullet drop hash marks for hold overs out to 800 meters.

Cons

  • Fixed 3.5x magnification is not ideal for bolt action and long-range specific rifles.

The military has adopted a handful of Nightforce optics because they’re durable and high-performance. The Nightforce SHV 5-20x56mm Riflescope might be pricey, but you’re getting legitimate military-grade optics.

First, this scope is equipped with a 5-20x magnification range. The magnification range skews toward long-range shooting. But, the low end magnification is low enough to scan wide space and identify targets.

The reticle is non-illuminated. But, it offers an extensive system of hash marks for windage and range estimation and hold overs. So, the reticle itself helps you make more accurate calculations and shots.

And, the objective lens is 56mm, which is massive. And, Nightforce uses incredibly clear glass, paired with multi-layer lens coatingsThis produces an incredibly bright and clear image, even in low-light conditions.

This scope is at the very high end of the price spectrum and will most likely appeal to competition and tactical long range shooters. But, it’s an incredible scope for any long range .308 rifle.

Pros

  • Powerful magnification range.
  • Extremely clear glass and a huge objective lens for an ultra-clear image.
  • Very useful reticle.

Cons

  • Non-illuminated reticle.
