Best Scope for OP SKS: Top 5 Scopes That Transform the Soviet Classic

The best scope for OP SKS should bring out the full potential of this rugged Soviet carbine without overcomplicating its straightforward charm. The SKS, with its fixed 10-round magazine and semi-auto 7.62x39 chambering, is a surprisingly accurate and reliable rifle—especially when properly scoped.
Over the years, I’ve mounted a dozen different optics on my Russian, Chinese, and Yugoslav SKS rifles, testing everything from budget bug-busters to premium glass in low-light forest hunts and at 300-yard steel targets.
Below, I’ve narrowed it down to five scopes that truly balance performance, value, and compatibility with the OP SKS platform.

🏆 Top Scopes for OP SKS (Quick Picks)

Glass Clarity & Reticle

The glass on the Crossfire II punches above its price point. I mounted it on my OP SKS with a Choate mount and 20mm rings, and tested it on a 100–300 yard range. The Dead-Hold BDC reticle allows for easy drop estimation at 200 yards — which aligns nicely with the SKS’s ballistic curve.

Eye Relief & Eye Box

The eye relief at nearly 4 inches is forgiving. Even during fast follow-up shots from standing or kneeling positions, I didn’t lose the sight picture.

Durability

I’ve put over 500 rounds of 7.62x39 (123gr FMJ) through it. The scope handled recoil and vibration flawlessly. It’s shockproof, nitrogen purged, and O-ring sealed.

Turrets & Tracking

The capped turrets have clean, tactile clicks. I performed a mini box test at 100 yards, and the Crossfire II tracked accurately within ¼ MOA.

My Experience

Mounted on my Yugo M59/66 SKS, it transformed the rifle’s practical accuracy. I consistently grouped 1.5–2 inches at 100 yards with surplus ammo.

Verdict

For shooters wanting a classic variable optic with proven reliability and clear glass, the Vortex Crossfire II 3-9x40 is my top pick for most OP SKS setups.

2. Burris Scout Scope

My Experience

For tactical-style training, I shot drills at 25–200 yards using both eyes open at 1x and zoomed to 4–6x for steel hits. The reticle’s ballistic subtensions match surprisingly well to 7.62x39 out to 300 yards.

Verdict

If you want your OP SKS to feel like a modern combat rifle, the Primary Arms SLX 1-6x24 LPVO offers outstanding speed and flexibility.

4. Leupold VX-Freedom 3-9x40

🔍 How to Choose the Right Scope for an OP SKS

Selecting the best scope for OP SKS requires balancing realism with performance. Here’s what I’ve learned after years of shooting and experimenting:
Mounting System: SKS rifles often need side mounts or scout rails. Forward “scout” mounts preserve shell ejection and stripper clip use.
Magnification Range: 1–6x LPVOs are great for dynamic shooting; 3–9x or 4–12x work best for hunting and mid-range accuracy.
Weight & Balance: Keep the optic under 16 oz to preserve SKS balance. Heavy optics make it front-heavy and sluggish.
Durability: Ensure shockproof and nitrogen purged construction. The SKS recoil may be mild but sustained vibration tests a scope’s internals.
Reticle & Focal Plane: SFP scopes (like the Crossfire II or Leupold VX-Freedom) work best for traditional use, while FFP designs suit tactical or competition shooting.
Eye Relief: Aim for at least 3.5 inches. Long-eye-relief models (like the Burris Scout) are best for forward mounting.
Budget Considerations: Don’t overinvest—an SKS scope between $100–$300 can already deliver excellent results.

❓ FAQs About OP SKS Scopes

Q1: Can you mount a regular rifle scope on an SKS? Yes, but it depends on your mounting system. Most SKS rifles require a side rail or scout mount to achieve proper eye relief and clearance for the bolt carrier.
Q2: What’s the best magnification for an SKS scope? 3–9x is ideal for mid-range hunting. For tactical setups, 1–6x LPVOs provide both speed and precision.
Q3: Does the SKS benefit from an illuminated reticle? Absolutely. The 7.62x39 round often sees use in wooded areas or low light — illumination improves visibility on darker targets.
Q4: How far can you effectively shoot an SKS with a scope? With good ammo and optics, you can achieve consistent hits out to 300–400 yards, though practical accuracy peaks around 250 yards.
Q5: Can the SKS handle heavy scopes? It can, but avoid scopes over 18 ounces unless you have a sturdy mount. Heavy optics shift balance and increase wear on mounts.
Q6: What’s the best mounting option for SKS scopes? For simplicity and reliability, side receiver mounts or scout rails are the most effective.
Q7: Can you still use iron sights with a mounted scope? Yes, if you choose a see-through or offset mount. This preserves backup sight alignment.

🧾 Conclusion

The OP SKS is a rugged platform that rewards practical optics. After extensive testing, my top recommendation remains the Vortex Crossfire II 3-9x40 for its balance of clarity, value, and reliability. For a forward scout setup, the Burris Scout Scope is unbeatable. Tactical shooters, however, will love the versatility of the Primary Arms SLX 1-6x24 LPVO.
Ultimately, the best scope for OP SKS depends on how you shoot—precision, speed, or field utility—but each of these optics brings out the full potential of this timeless rifle while keeping its Soviet soul intact.
