The FN SCAR 17S is one of the most capable 7.62×51 semi-automatic hunting platforms available to American hunters.
It is also one of the most demanding on the scopes mounted to it. The SCAR 17’s short stroke gas system and reciprocating charging handle generate a distinctive recoil impulse that has revealed weaknesses in optics that hold up fine on bolt action rifles. Mount the wrong scope on a SCAR 17 and you are dealing with shifting zeros, cracked tube bodies, or lost reticle adjustments before the season ends.
The optics that earn their place on a SCAR 17 for hunting are those that were built to survive genuine abuse.
The 7.62×51 cartridge also asks specific questions about the hunting application: are you running this rifle in timber where 4x is plenty, or pushing it to 500 yards across an open basin where 20x makes the difference?
The SCAR 17’s semi-automatic capability shifts the question further toward close to medium range scenarios where follow up shots on dangerous or fast moving game are in play.
The six scopes below are selected for durability, optical performance, and specific match to 7.62×51 hunting applications on the SCAR 17 platform.

1. Vortex Razor HD Gen II-E 1-6×24 – Best Overall LPVO
The SCAR 17 was built as a platform capable of both close-quarters engagement and medium-distance precision work. The Razor HD Gen II-E 1-6×24 matches that versatility with a true 1x low end for both eyes-open shooting at close range and a 6x top end that supports clean deer and elk shots past 400 yards with 7.62×51.
At 3.7 inches of eye relief and a 23.1-ounce weight, the Razor HD sits well on the SCAR 17’s flat top rail without making the rifle muzzle light or changing the familiar handling.
The Razor HD’s APO glass tier is the second highest in Vortex’s product hierarchy, and it shows in field conditions. At 6x in the last light of an October evening on elk in a timber draw, the image quality rivals European optics that cost twice as much. The JM-1 BDC reticle provides holdover references for 7.62×51 out to 600 yards.
At 1x the Razor HD Gen II-E is a genuine 1x: the JM-1 horseshoe reticle is visible with both eyes open and provides a fast, accurate close range aiming reference for a follow up shot on a running animal.
The Razor HD Gen II-E 1-6×24 is the scope that makes the SCAR 17 the hunting rifle it was built to be: from a mule deer at 30 yards in a brushy wash to a bull elk at 350 yards across a meadow, this scope handles the full range of 7.62×51 big game hunting without a tradeoff. Its APO glass holds up at last light in the field. Vortex VIP warranty: unconditional, lifetime, transferable. The most versatile and practical hunting scope match for the SCAR 17.
Pros
- APO glass delivers premium optical performance at dawn and dusk
- True 1x with JM-1 horseshoe reticle for both eyes open close range shooting
- 6x top end covers confident shot placement on big game past 400 yards
- Gen II-E eye box is fast and forgiving under field conditions
- 3.7 inch eye relief is generous for a semi-automatic platform with .308 recoil
- Vortex VIP warranty: unconditional, lifetime, transferable
Cons
- 23.1 ounce weight adds up on a rifle that already weighs 7.25 pounds empty
- 6x maximum limits confidence at 500 to 600 yard shots in dim conditions
- Premium price tier
2. Nightforce NX8 2.5-20×50 F1 – Best Premium Long Range
If the SCAR 17 is being used as a precision long range hunting platform where shots past 500 yards are the point, the Nightforce NX8 is the answer. At 20x with a 50mm objective the NX8 resolves targets at distance with a clarity and brightness that places it in a separate category from the LPVO options on this list.
The NX8’s first focal plane design means the MOAR-T reticle subtensions remain accurate at every magnification setting, which is essential for range estimation and holdover on a scope that spans 2.5x to 20x. At 3.9 inches eye relief and the SCAR 17’s recoil impulse, the NX8 is one of the few scopes built to hold up long term on this platform.
Nightforce builds to a different standard than most scope manufacturers, and the NX8 demonstrates this in the field. At 20x in a 400 yard shot scenario on a deer in fading afternoon light, the NX8 produces an image that makes the SCAR 17 a legitimate long range hunting tool. The MOAR-T reticle is precise, scalable, and readable in low light.
The 50mm objective and Nightforce’s proprietary coatings gather light at high magnification. At 15x to 20x in hunting light the image remains usable well past the point where standard glass has quit.
The Nightforce NX8 is the correct scope for the SCAR 17 hunter who uses the rifle for open country big game at distances where 7.62×51 still delivers terminal performance but 20x of magnification is needed to read the shot. Elk at 500 yards in Montana or whitetails across a 400 yard agricultural field in Kansas are the scenarios this scope was built for on this platform. Nightforce limited warranty. The premier long range hunting optic for the SCAR 17.
Pros
- 2.5-20x magnification covers close range and extreme long range hunting scenarios
- FFP reticle maintains accurate subtensions at all magnification settings
- 50mm objective and premium coatings deliver best in class low light performance
- Nightforce build quality is the standard for surviving hard recoiling platforms
- 3.9 inch eye relief is safe and comfortable for .308 semi-automatic recoil
- Nightforce limited warranty
Cons
- 30 ounce weight is significant on a SCAR 17 carry rifle
- Premium price tier is the highest on this list
- 2.5x minimum magnification is wider than most LPVO options for close range work
3. Vortex Viper PST Gen II 1-6×24 – Best Mid Range LPVO
The Viper PST Gen II 1-6×24 is the mid tier LPVO option that covers the SCAR 17’s most practical hunting magnification range at a step below the Razor HD’s premium price. At 22.5 ounces it is the lightest LPVO on this list and handles with the SCAR 17’s natural carry balance.
The EBR-2C reticle provides holdover references for 7.62×51 at common hunting distances. The 3.5 inch eye relief is comfortable for a semi-automatic platform with .308 recoil and consistent across standard shooting positions.
The Viper PST Gen II uses HP glass, a step above the Strike Eagle and a step below the Razor HD. In field hunting conditions during the main hunting hours from full light to an hour before dusk, the optical quality is very good for its price tier. The image is sharp, contrasty, and consistent across the 1-6x magnification range.
At last light in heavy timber the HP glass shows limits compared to the Razor HD APO, but for most deer and elk hunting scenarios in open terrain it performs well inside the critical shooting hours.
The Viper PST Gen II 1-6×24 is the practical mid tier LPVO for the SCAR 17 hunter who wants a versatile 1x to 6x hunting scope with better glass than the Strike Eagle and genuine zero retention reliability on a hard use platform. For deer hunters who keep shots inside 350 yards in mixed terrain, this scope covers every scenario without the Razor HD’s premium investment. Vortex VIP warranty: unconditional, lifetime, transferable. A strong mid tier choice for the SCAR 17 hunting rifle.
Pros
- HP glass delivers above average image quality in the main hunting hours
- True 1x for both eyes open close range field shooting
- 22.5 ounces is the lightest LPVO on this list
- EBR-2C reticle provides 7.62×51 holdover references
- Vortex VIP warranty: unconditional, lifetime, transferable
Cons
- HP glass shows limits compared to Razor HD at last light in dense timber
- 3.5 inch eye relief is on the lower end of comfortable for a .308 semi-automatic
- 6x maximum limits precision at shots past 400 yards in lower light
4. Leupold VX-3HD 3.5-10×40 – Best Traditional Hunting Scope
Not every SCAR 17 hunter needs an LPVO or a tactical style optic. For the hunter who runs the SCAR 17 as a semi-automatic .308 in whitetail timber, a traditional hunting scope profile makes sense. The VX-3HD 3.5-10×40 gives a 3.5x minimum for timber shots and a 10x maximum for confident open country work at 350 yards.
At 13.5 ounces the VX-3HD is the lightest scope on this list and transforms the SCAR 17 into a far more carried-than-shot woods rifle. The 4.0 inch eye relief is the most generous available and the safest margin for a 7.62×51 semi-automatic platform.
Leupold’s HD glass tier with Twilight Max Light Management coatings delivers outstanding optical performance for a traditional 3-10x hunting scope. At first and last light in a timbered bottom the VX-3HD holds contrast and image clarity longer than any standard or HP coated option.
The Wind-Plex reticle provides windage holdoff reference points while maintaining a clean field hunting appearance. At 10x the image quality is sufficient for a 350 yard deer shot in good light on the SCAR 17’s 7.62×51 capability.
The VX-3HD 3.5-10×40 is the correct scope for the SCAR 17 hunter who uses the rifle as a woods and mixed terrain deer or hog rifle where the semi-automatic capability matter more than long range precision. The light weight, premium glass, and generous eye relief make this a genuine hunting scope on a genuine hunting platform. Leupold lifetime warranty. The best traditional hunting scope match for the SCAR 17.
Pros
- Lightest scope on this list at 13.5 ounces
- Twilight Max coatings deliver the best low light image on this list
- 4.0 inch eye relief is the most generous and safest for .308 semi-automatic recoil
- Traditional hunting profile keeps the SCAR 17 feeling like a hunting rifle
- Wind-Plex reticle provides windage reference without tactical clutter
- Leupold lifetime warranty
Cons
- 3.5x minimum is not a true 1x and limits both eyes open close range shooting
- 10x maximum is less than the LPVO options for longer range precision
- Traditional profile limits the SCAR 17’s tactical hunting versatility
5. Vortex Strike Eagle 1-8×24 – Best Budget LPVO
The Strike Eagle 1-8×24 is the entry point into 1x to 8x LPVO performance for the SCAR 17 hunter who wants a versatile close to medium range scope without a premium investment. At 17 ounces it is a reasonable weight on the SCAR 17’s flat top rail. The 3.5 inch eye relief is adequate for 7.62×51 semi-automatic use with a disciplined shooting position.
The AR-BDC3 reticle provides holdover reference points calibrated for 7.62×51 velocity at standard hunting distances. The 8x top end adds useful magnification over standard LPVO options for 250 to 350 yard deer hunting scenarios.
The Strike Eagle uses standard multi-coated glass, which is a step below the HP and APO tiers above it on this list. In good midday hunting light it performs for a hunting scope. At dawn and dusk in heavy timber the standard coating tier shows limitations that are meaningful on a deer rifle in the final hour of shooting light.
The AR-BDC3 reticle is busy in appearance but provides the holdover data needed for 7.62×51 shots at 300 to 400 yards for hunters who do the range work to confirm the calibration.
The Strike Eagle 1-8×24 is the right budget LPVO for the SCAR 17 hunter who needs 1x to 8x versatility without the Razor HD price. Its glass quality limitations at last light are a real constraint on a rifle that excels in low light semi-automatic follow up shot scenarios. For daytime deer hunters who work in open terrain the glass limitation is less significant. Vortex VIP warranty: unconditional, lifetime, transferable. A workable starting point for the budget minded SCAR 17 hunter.
Pros
- 1x to 8x covers the full close to medium range SCAR 17 hunting spectrum
- AR-BDC3 reticle is calibrated for 7.62×51 holdover at hunting distances
- 17 ounce weight is reasonable on the SCAR 17 platform
- Budget price tier for LPVO capability
- Vortex VIP warranty: unconditional, lifetime, transferable
Cons
- Standard glass shows low light limits that matter on a dawn and dusk hunting rifle
- 3.5 inch eye relief is the minimum safe margin for 7.62×51 semi-automatic recoil
- Busy reticle appearance requires range time to learn and use
6. Primary Arms GLx 2-10×44 FFP – Best Value First Focal Plane
The Primary Arms GLx 2-10×44 offers first focal plane performance at a price tier that would have been impossible for FFP optics five years ago. On the SCAR 17, the FFP design means the ACSS Raptor reticle’s holdover marks and ranging hash marks remain accurate at every magnification setting from 2x to 10x.
The 2x minimum gives a workable field of view for hunting in mixed terrain. The 10x top end supports confident big game shot placement at 400 yards in good field conditions. The 44mm objective gathers useful light for hunting in open terrain at dawn.
Primary Arms classifies the GLx glass as an XD grade equivalent, and in field conditions it performs closer to the HP tier in real hunting light. The ACSS Raptor reticle uses a horseshoe design at low magnification for rapid close range acquisition and calibrated bullet drop compensation marks at higher power.
At 10x in good light the GLx holds a sharp image for big game identification and shot placement. At last light in timber the glass shows limits. The FFP design is the genuine differentiator: ranging and holdover accuracy that standard SFP scopes cannot replicate at varied magnification settings.
The Primary Arms GLx 2-10×44 FFP is the correct choice for the SCAR 17 hunter who wants the accuracy benefits of a first focal plane reticle at a mid tier price. The ACSS Raptor reticle is useful for 7.62×51 hunting in open country where precise holdover matter. Primary Arms lifetime warranty. A strong value option for the hunter who wants FFP performance without the Nightforce premium.
Pros
- FFP design keeps reticle subtensions accurate at every magnification setting
- ACSS Raptor reticle provides close range horseshoe and long range holdover in one design
- 2-10x covers close range hunting and medium range precision scenarios
- XD grade glass delivers above standard image quality for the price tier
- Primary Arms lifetime warranty
Cons
- 3.2 inch eye relief is the minimum safe margin for 7.62×51 recoil on a semi-automatic
- Glass quality does not match the Razor HD or Nightforce at last light
- 10x maximum is limiting at the SCAR 17’s maximum practical hunting range
Eye Relief Safety Notes: 7.62×51 on a Semi-Automatic Platform
The SCAR 17’s recoil impulse is different from a bolt action .308. The short stroke gas system cycles more and with less of the gradual push of a traditional bolt gun. The practical impact on eye relief safety is that a scope mounted with less than 3.5 inches of eye relief on a SCAR 17 will contact the shooter’s brow or orbital bone during rapid fire strings, which is a different scenario from a single bolt action shot.
The Leupold VX-3HD’s 4.0 inch eye relief is the safest margin on this list for a SCAR 17 used in hunting scenarios where rapid follow up shots on running game or driven hogs are expected. The 3.5 inch options on this list are adequate for deliberate aimed shots but leave minimal margin for a less-than-textbook cheek weld position in the field.
Never mount a scope with less than 3.5 inches of eye relief on the SCAR 17 for hunting use. A scope that works on a bolt action .30-06 at 3.2 inches is a different calculation on a 7.62×51 semi-automatic in a running deer scenario.
Field Notes: SCAR 17 Scope Selection
Zero retention is the non-negotiable requirement on the SCAR 17
The SCAR 17’s recoil impulse has shown up structural weaknesses in optics that hold zero on bolt action rifles. Every scope on this list is rated for the SCAR 17’s operating conditions, but mounting quality matter as much as scope quality. Use quality steel rings with proper torque specs. A quality scope in loose rings performs worse than a budget scope mounted.
LPVO versus traditional scope depends on the hunting terrain
In timber where deer appear inside 80 yards and follow up shots on running animals are, an LPVO at 1x is a different tool than a 3.5x traditional hunting scope. In open mule deer country where shots start at 200 yards and extend to 450, a 10x to 20x scope is the right answer. The SCAR 17 is capable of both; know your terrain before selecting the configuration.
The 7.62×51 deserves field tested glass quality
The SCAR 17 in 7.62×51 is a capable long range hunting cartridge in a reliable semi-automatic platform. Running standard glass on a rifle this capable is like using an accurate hunting rifle to push the edge of its performance with mediocre ammo. The HP and APO tier glass options on this list produce real world hunting results that justify the investment on a platform you are trusting with your season’s best opportunity.
Final Thoughts
For the SCAR 17 hunter who wants the most versatile, field-practical scope on a hard use 7.62×51 platform, the Vortex Razor HD Gen II-E 1-6×24 delivers APO glass, true 1x versatility, and a JM-1 BDC reticle in a package that matches this rifle’s hunting capability from heavy timber to 400 yard open country shots.
For dedicated long range hunters who are pushing the 7.62×51 past 400 yards on elk and open country big game, the Nightforce NX8 2.5-20×50 F1 is the uncompromised answer in glass, reticle precision, and platform durability. The Leupold VX-3HD 3.5-10×40 earns its place for any SCAR 17 hunter who prioritizes lightweight, premium low light glass, and the safest possible eye relief margin on a semi-automatic .308. Step into the field with the right optic matched to your terrain and the SCAR 17 will deliver every capability it promises.
