The .308 Winchester is the most used precision rifle cartridge in the world for one reason: it works.
It has been refined over 70 years of military, law enforcement, competition, and hunting use into a round that hits hard, maintains supersonic velocity past 800 yards, and feeds in every action type from bolt to semi-auto. The ballistic data on .308 is better documented than almost any other cartridge available.
The .308 has well-established drop tables at every common load weight. At 175 grains, a .308 drops 77 inches at 500 yards from a 100-yard zero.
At 800 yards, it has dropped around 400 inches. A scope with an FFP reticle calibrated in MRAD or MOA turns those numbers into a usable shooting system.
The .308 is also used across a wider range of applications than almost any other rifle cartridge.
In deer and elk hunting, precision long-range target shooting, tactical and service rifle competition, and military training all use the .308 in different ways. The scope choice varies.
Vortex covers every .308 application from an entry-level hunting build to a serious precision rig. These five picks are matched to the most common use cases for this cartridge at every price point.

#1 Vortex Viper PST Gen II 5-25×50 – Best Overall</h2>
The .308 Winchester at 500 yards is a precision shooting problem, not a hunting problem. It requires accurate elevation input, wind reading, and a reticle system that lets you make corrections without stopping to calculate. The Viper PST Gen II 5-25×50 is built around that reality.
The EBR-2C reticle in the first focal plane is why this scope earns the top spot on a .308.
Whether you are dialing to a known distance or holding for a wind correction at 400 yards, the MRAD or MOA subtensions are correct at every magnification. That is the precision tool the .308’s documented ballistics deserve.
At 25x the resolution is sufficient to call impacts in the dirt around an 8-inch target at 600 yards. That feedback loop, seeing where the round went and correcting, is how skilled .308 shooters extend their effective range. The 25x top end makes it possible.
The zero-stop exposed turrets are the right mechanics for a precision .308 build. They return to zero with authority, count and hold their setting across sustained shooting sessions. Vortex has put serious engineering into this turret at the PST Gen II tier.
The 30mm tube and 50mm objective maximize adjustment range and light gathering. This scope has backing by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 5-25x |
| Objective Lens | 50mm |
| Tube Diameter | 30mm |
| Reticle | EBR-2C MOA or MRAD (FFP) |
| Eye Relief | 3.7 inches |
| Weight | 26.8 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- FFP reticle accurate at every magnification setting for ranging and holdovers
- 25x top end gives genuine resolution for 600-yard and beyond work
- Zero-stop turrets hold under sustained .308 shooting sessions
- VIP warranty is unconditional and lifetime
Cons
- 5x low end is higher than ideal for hunting use in timber</li>
- 26.8 oz is heavy for a hunting rifle build
- Price is a significant investment compared to the Viper HS tier</li>
Our Take
For a .308 rifle set up for precision long-range shooting, the Viper PST Gen II 5-25×50 is the scope that matches the cartridge’s full capability. It removes the optical limitations, provides the precision tools the ballistics deserve, and backs everything up with an unconditional lifetime warranty.
#2 Vortex Viper HS 4-16×44 – Best for Hunting
The .308 Winchester is one of the most effective deer and elk cartridges available. It hits hard at hunting distances, fits in a compact bolt action, and produces manageable recoil for accurate follow-up shots. The Viper HS 4-16×44 is the scope matched to that hunting application.
The XD extra-low dispersion glass is the practical advantage of this scope over the Diamondback tier.
At dawn and dusk in a hunting situation, the glass quality difference between XD and standard multi-coat becomes visible in the image brightness and edge clarity. For a .308 deer or elk hunter, that difference can matter at the moment of truth.
The 4x low end gives a practical field of view for close-range hunting shots in timber. A .308 is used in mixed terrain where shot distances range from 50 yards to 400 yards. The 4x to 16x range covers that full spectrum.
The Dead-Hold BDC reticle is calibrated for .308 Win centerfire trajectories at hunting distances. Paired with a standard 168-grain .308 load, the holdover points are practical at 300 to 400 yards without elevation dialing in the field.
The 30mm tube gives the elevation adjustment range needed for a .308 hunting setup that pushes past 400 yards. This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 4-16x |
| Objective Lens | 44mm |
| Tube Diameter | 30mm |
| Reticle | Dead-Hold BDC (SFP) |
| Eye Relief | 4 inches |
| Weight | 16.7 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- XD glass delivers excellent low light performance for hunting applications
- 4-16x covers close range timber shots through 400 yard open country work
- Dead-Hold BDC is practical for .308 field trajectories at hunting distances
- 16.7 oz is a reasonable weight for a hunting rifle build
Cons
- Second focal plane limits BDC accuracy to maximum magnification
- Capped turrets are less suited to precision long range dialing
- Not the right choice for a dedicated precision .308 competition build
Our Take
The Viper HS 4-16×44 is the right Vortex scope for a .308 hunting rifle. The XD glass, practical BDC reticle, and 30mm tube deliver everything a .308 hunter needs in the field, backed by the unconditional VIP warranty.
#3 Vortex Razor HD Gen III 6-36×56 – Best Premium
The Razor HD Gen III is the top of the Vortex production lineup and one of the most capable precision rifle scopes available from any manufacturer. On a .308 rifle built for serious long-range work, it removes every optical limitation the platform has.
The APO apochromatic lens system corrects chromatic aberration across the full color spectrum.
The result is a level of edge clarity, color accuracy, and image resolution that sits in a category above every other scope on this list. At 36x on a .308 at 800 yards, the image quality is what separates a clear call from a guess.
The 6-36x magnification range is for precision long-range applications. The 6x low end is workable for hunting situations. The 36x top end gives resolution at 1,000 yards for a .308 shooter who has the skill to use it.
The EBR-7D reticle in first focal plane provides a complete ranging and holdover system. The 34mm main tube maximizes elevation and windage adjustment travel, which matters on a .308 at 800 to 1,000 yards where significant elevation dial is required.
Exposed zero-stop turrets with clear, tactile clicks complete a precision shooting system that competes with scopes at twice the price. This scope has backing by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 6-36x |
| Objective Lens | 56mm |
| Tube Diameter | 34mm |
| Reticle | EBR-7D MRAD (FFP) |
| Eye Relief | 3.8 inches |
| Weight | 37.2 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- APO glass delivers best-in-class optical quality in the Vortex lineup
- 36x top end gives genuine resolution for 800 to 1,000 yard .308 work
- 34mm tube provides maximum elevation adjustment travel
- FFP reticle accurate at all magnification settings
Cons
- 37.2 oz is heavy and limits its use to static precision shooting applications
- Price is the highest on this list
- 6x low end is less versatile for hunting use than lower-starting scopes</li>
Our Take
If your .308 rifle is a precision long-range platform and you want the best glass Vortex produces, the Razor HD Gen III 6-36×56 is the answer. It is overkill for a hunting rifle. It is right for a serious precision shooting build.
#4 Vortex Diamondback HP 4-16×42 – Best Budget Pick
The Diamondback HP is the honest budget answer for a .308 rifle for hunting and moderate precision distances. It delivers the same 4-16x zoom range as the Viper HS at a lower price, with trade-offs in glass quality at the margins of light and adjustment range.
The multi-coated glass handles standard daylight conditions. For a .308 hunter or shooter working inside 400 yards in good light, the performance gap between this scope and the Viper HS is narrower than the price difference.
The Dead-Hold BDC reticle gives practical holdover points at .308 hunting and field distances.
The 1-inch tube is the main mechanical limitation unlike the 30mm options on this list. It limits total elevation adjustment travel, which matters more on a .308 at extended range than on a lighter cartridge.
Build quality is solid and zero retention is reliable across sustained .308 shooting. This scope has a backing by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 4-16x |
| Objective Lens | 42mm |
| Tube Diameter | 1 inch |
| Reticle | Dead-Hold BDC (SFP) |
| Eye Relief | 3.8 inches |
| Weight | 15.7 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- Strong value for a 4-16x scope with a proven BDC reticle
- Same zoom range as the Viper HS at a lower price
- Reliable zero retention under sustained .308 use
- VIP warranty unconditional and lifetime
Cons
- Glass quality steps down from the Viper HS in low light
- 1-inch tube limits elevation adjustment range for extended-range .308 work
- Not suitable for precision long-range dialing past 500 yards
Our Take
The Diamondback HP is the right budget scope for a .308 hunting rifle or a moderate range precision build. It delivers honest performance at practical distances and carries the same unconditional lifetime VIP warranty as everything else Vortex makes.
#5 Vortex Strike Eagle 4-24×50 – Best Value FFP
The Strike Eagle 4-24×50 gives a .308 shooter first focal plane capability and 24x magnification at a price well below the Viper PST Gen II. For a shooter who wants FFP holdovers and extended magnification without the full PST price, this is the honest middle ground.
The AR-BDC3 reticle in FFP is accurate at every magnification setting. On a .308 where shots happen at varying distances in varying conditions, the ability to hold at any power setting without mental math is a genuine practical advantage.
The 4-24x range covers hunting distances at the low end and genuine precision work at the top. At 24x the .308 shooter can see impacts in the dirt at 600 yards and make real-time corrections without a spotter.
The exposed zero stop turrets provide precise elevation input with 0.1 MRAD clicks. For a .308 precision build on a budget, the turret mechanics on the Strike Eagle are honest and functional. Zero retention under sustained .308 fire is reliable.
The 50mm objective provides strong light gathering for hunting and field shooting in variable conditions. This scope has a backing by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 4-24x |
| Objective Lens | 50mm |
| Tube Diameter | 30mm |
| Reticle | AR-BDC3 (FFP) |
| Eye Relief | 3.5 inches |
| Weight | 23.3 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- FFP reticle delivers accurate holdovers at all magnification settings
- 4-24x covers hunting through genuine precision long range work
- Lower price than the Viper PST Gen II for similar FFP functionality</li>
- 50mm objective provides strong light gathering
Cons
- Eye relief at 3.5 inches is on the shorter side
- Glass quality is below the Viper PST Gen II tier
- 23.3 oz is on the heavier side for a hunting build
Our Take
The Strike Eagle 4-24×50 is the right choice for a .308 shooter who wants first focal plane performance and extended magnification without paying Viper PST Gen II prices. It delivers genuine precision capability backed by the same unconditional lifetime VIP warranty as every other scope on this list.
Did You Know? The .308 Winchester and the 7.62x51mm NATO are identical but are not interchangeable. The NATO round is loaded to different pressure specifications. A .308 Win chamber can fire both, but a 7.62 NATO chamber should not be used with commercial .308 ammunition in all cases. This distinction matters for the rifle choice, not the scope, but it is the most misunderstood fact about the cartridge.
Frequently Asked Questions: Best Vortex Scope for 308
What magnification do I need for a Vortex scope on a .308?
For hunting inside 400 yards, a 4-16x covers the practical range of the cartridge. For precision shooting at 500 to 800 yards, a 5-25x or 4-24x gives the resolution to work at the cartridge’s long range capability.
Do I need an FFP Vortex scope for a .308?
>>>>>>>>>>>Yes, if you are using the .308 for precision long range work where holdovers and ranging at varied magnification are part of the shooting system. For hunting use at a consistent power setting, an SFP scope like the Viper HS is simpler and effective.
Which Vortex scope holds zero best under sustained .308 shooting?
All five scopes on this list are built to hold zero under sustaining .308 use. The Viper PST Gen II and Razor HD Gen III have the most robust turret systems for precision applications where zero retention is tested.
Is the Vortex Viper PST Gen II worth the price on a .308?
Yes, for a shooter who uses the .308 for precision work past 400 yards. The FFP reticle, zero stop turrets, and 25x magnification justify the price for any serious precision .308 application.
What tube diameter is best for a Vortex scope on a .308?
A 30mm tube is the right choice for a .308 that gets used past 400 yards. It provides more total elevation adjustment travel than 1 inch, which matters on a cartridge with significant drop at longer distances.
Verdict
The .308 Winchester is the most documented precision rifle cartridge in the world. It deserves a scope that can use that documentation rather than ignore it.
For precision long range shooting, the Viper PST Gen II 5-25×50 is the best. The FFP reticle, zero stop turrets, and 25x top end match the cartridge’s full capability and give the shooter the tools to use it.
For a hunting-first .308 build, the Viper HS 4-16×44 delivers XD glass and a practical BDC reticle in a weight and format that works in the field. For a budget-conscious build inside 400 yards, the Diamondback HP covers the practical range of the cartridge at a lower price with the same lifetime VIP warranty.
The Strike Eagle 4-24×50 is the honest middle ground for a shooter who wants FFP performance without PST Gen II pricing. And for a serious precision rig where glass quality is the priority, the Razor HD Gen III is the best scope Vortex makes and one of the best available from any manufacturer.
The .308 Winchester has 70 years of proven performance behind it. Give it a Vortex scope that matches that standard.
