For most .308 rifles, a 3–9x or 2.5–10x scope is an excellent choice for hunting and general-purpose shooting. If you regularly shoot at longer distances, a 4–16x scope provides more magnification without making the rifle excessively heavy or specialized.
The best scope for a .308 depends primarily on how far you shoot and what the rifle is used for. Hunters usually benefit from moderate magnification, good light transmission and a wide field of view, while long-range shooters may want more magnification, adjustable parallax and more advanced reticles.
Quick guide:
- Hunting: 3–9x40
- All-around use: 2.5–10x40
- Long range: 4–16x50
- Dedicated precision shooting: 6–24x50
Below we'll break down magnification, reticles, objective size, eye relief and the other features that matter when choosing a scope for a .308 rifle.
First: Why the .308 Is So Versatile
The reason choosing a scope for a .308 can be tricky is because the cartridge itself does so many things well.
A .308 can be used for:
- Deer hunting
- Elk hunting
- Hog hunting
- Long-range target shooting
- Tactical applications
- General-purpose rifle setups
That’s a huge range of use.
A .223 setup and a .308 setup are not the same.
A .308 has more reach.
More power.
More recoil.
And typically gets used in more varied environments.
So your optic needs to match that.
The First Question You Need to Ask
Before you buy a scope, ask yourself:
What is this rifle primarily for?
That one question narrows everything down.
Because a hunting scope for .308 looks very different than a long-range precision scope for .308.
If You’re Hunting with a .308
This is probably the most common use.
And honestly, for hunting, people overcomplicate optics way too much.
For most hunting applications:
You do NOT need a massive 6-24x scope.
You do NOT need giant tactical turrets.
And you do NOT need an ultra-heavy setup.
What you need is:
- clarity
- reliability
- practical magnification
- good light transmission
That’s it.
Best Scope Magnification for a .308 Hunting Rifle
For most hunters:
3-9x is king.
It has been for decades for a reason.
At 3x:
Fast target acquisition.
At 9x:
Plenty of reach for most hunting situations.
That’s a sweet spot.
Another great option:
2.5-10x
This gives you a little extra flexibility.
Better for mixed terrain.
Good for:
- timber
- open field
- mountain hunting
A very strong all-around option.
Best Long-Range Scope Magnification for .308
Now things change.
If you’re stretching your .308 out to:
500 yards
700 yards
800 yards+
You need more precision.
That means:
More magnification.
Better turret tracking.
Better reticle options.
Ideal magnification here:
4-16x
This is where a .308 really starts to shine.
Enough magnification for precision.
Not too much bulk.
Still practical.
If you’re going serious:
6-24x
This is more dedicated long-range territory.
Good for:
- bench shooting
- precision work
- steel shooting
But it’s not ideal for hunting in most situations.
Too bulky.
Too slow.
Too specialized.
Reticle Choice Matters More Than People Think
People obsess over magnification.
But reticles matter just as much.
Maybe more.
For hunting:
Simple is better.
A clean duplex or Mil-Dot reticle works great.
You want:
Fast sight picture.
Quick shot placement.
Minimal clutter.
For long range:
Mil-Dot or MOA reticles become much more useful.
Why?
Because holdovers matter.
Corrections matter.
Precision matters.
If you’re not familiar with this:

Understanding this changes everything.
Objective Lens Size
Another place people overdo it.
Bigger isn’t always better.
Good range for .308:
40mm–50mm
That’s the sweet spot.
Why?
Good light gathering.
Reasonable size.
Balanced weight.
A 56mm objective sounds cool.
But now you’ve got:
- extra weight
- higher mounting height
- bulkier rifle
Not always worth it.
Durability Is Non-Negotiable
Especially for hunting.
Your scope will take abuse.
Rain.
Cold.
Bumps.
Travel.
Drops.
Field conditions.
So make sure your optic is:
- waterproof
- fogproof
- shockproof
This isn’t optional.
A .308 has recoil.
Your scope needs to handle it.
Eye Relief Matters on a .308
This caliber kicks more than smaller calibers.
Not brutal.
But enough.
And if your eye relief sucks:
You’ll know quickly.
Usually the hard way.
Look for:
3.5–4+ inches
That’s a good range.
Especially if you’re shooting from awkward hunting positions.
First Focal Plane or Second Focal Plane?
This gets overcomplicated.
Let’s simplify it.
Hunting?
Go Second Focal Plane (SFP)
Why?
Cleaner sight picture.
Easier to use.
More practical.
Long range?
First Focal Plane (FFP) can be useful.
Why?
Reticle stays accurate through magnification changes.
Useful for holdovers.
Range estimation.
Precision work.
But for the average .308 owner?
SFP is usually enough.
Don’t Over-Scope Your Rifle
This is one of the biggest mistakes.
A .308 is versatile.
That doesn’t mean it needs the biggest scope possible.
A huge scope can make your rifle:
- heavier
- slower
- more awkward
Think practical.
Not excessive.
My Personal Recommendation by Use
Let’s make this simple.
Best hunting setup:
View the Osprey Global 3–9x40 rifle scope →
Best for:
- deer
- elk
- hogs
- all-around hunting
Hard to beat.
Best all-around setup:
2.5-10x40
Probably the most versatile.
If you do a little bit of everything:
This is my favorite zone.
Best long-range setup:
View the Osprey Global Tactical 4–16x50 rifle scope →
Great balance.
Enough magnification.
Still practical.
Best dedicated precision setup:
6-24x50
For long-range specialists.
Not for everyone.
What About Budget?
Here’s the truth:
You do not need to spend $2,500 on a scope for a .308.
A lot of people get trapped into thinking expensive always means better.
Not necessarily.
What matters:
- tracking
- glass clarity
- durability
- reliability
Those are the priorities.
Not brand hype.
Final Thoughts: What’s the Best Scope for a .308?
If I had to simplify it:
For most people?
A 3-9x40 or 2.5-10x40 is the best choice.
Why?
Because most .308 shooters:
- hunt
- shoot under 400 yards
- want versatility
And those scopes do that extremely well.
If you’re shooting long range regularly:
Move into 4-16x or 6-24x territory.
But don’t buy more scope than you need.
That’s the key.
The best optic is the one that matches how you actually shoot.
Not how you imagine you might shoot someday.
And that’s the mistake most people make.
Build your rifle for reality.
Not fantasy.
That’s how you end up with a setup you actually love using.
