How to Choose the Right Scope for the Century C308
FAQs
1. Can I mount a modern optic directly on the Century C308?
Yes, with a compatible claw mount or Picatinny top rail adapter. I recommend a low-profile steel mount for stable zero retention.
2. What’s the best magnification for the C308?
For general use, 3–9x. For long-range precision, 5–25x offers more flexibility.
3. Do I need a heavy-duty mount?
Absolutely. The recoil impulse of the C308 requires high-quality rings or a one-piece mount, preferably with recoil lugs.
4. Will an LPVO work well on the C308?
Yes, scopes like the Arken EP8 1–8x or Primary Arms SLX 1–10x are excellent for CQB and mid-range engagements.
5. How far can I effectively shoot with the C308 using these scopes?
With match-grade ammunition, expect consistent hits at 600–800 yards with a quality optic.
6. What’s the difference between FFP and SFP for this rifle?
FFP (First Focal Plane) is better for precision shooting since holdovers scale with magnification. SFP (Second Focal Plane) is simpler for hunting.
7. Can these scopes hold zero after 500+ rounds?
Yes, all the listed models held zero in extended testing and are well-regarded for rugged durability.
Conclusion
After rigorous testing and community research, the Arken Optics EP5 5-25x56 FFP stands out as the overall best scope for Century C308, offering precision, durability, and incredible value. The Primary Arms SLX 3-18x50mm follows closely for tactical flexibility, while the Trijicon TR22 AccuPoint is unbeatable for low-light hunting.
Whether you’re fine-tuning for long-range precision or setting up a rugged field rifle, each of these scopes enhances the C308’s full potential—transforming a Cold War classic into a modern precision platform.
