Factors to Consider when Choosing Best Scope for Ruger 308
1. Magnification Range
Magnification is one of the first things to consider when choosing a scope for a Ruger .308. A 3-9x scope is a practical choice for general hunting because it provides a relatively wide field of view at low magnification while offering additional detail at higher magnification. Shooters who regularly engage targets at longer distances may prefer something such as 3-15x or 3-18x. However, higher magnification usually means a larger and heavier scope.
2. Reticle Type
The reticle should match your shooting style and the distances at which you expect to shoot. A traditional Duplex reticle is simple and uncluttered, making it easy to acquire targets quickly. A BDC reticle can provide additional holdover references for different distances, while an FFP reticle maintains its proportional relationship with the target as magnification changes. For a Ruger .308, make sure any BDC or ballistic reticle is appropriately calibrated or verified for your ammunition.
3. Objective Lens Size
Objective lens size affects light gathering, overall size, and mounting requirements. A 40mm objective offers a good balance between optical performance and a relatively manageable scope size. A larger 50mm objective, such as the one found on the Buckmasters and Primary Arms models discussed above, can provide greater light-gathering capability but may add weight and require higher mounting rings. Consider whether you prioritize portability or low-light performance.
4. Optical Quality and Lens Coatings
Clear glass is essential when hunting or shooting at longer distances. Look for scopes with quality glass and effective multi-coatings designed to improve light transmission, contrast, clarity, and glare reduction. Features such as low-dispersion glass and fully multi-coated lenses can be valuable when identifying targets in changing lighting conditions. Good optical quality can be more important than simply choosing the scope with the highest magnification.
5. Durability and Weather Resistance
A Ruger .308 may be used in rain, dust, cold temperatures, and other demanding outdoor conditions. A good scope should therefore have a rugged construction and be waterproof, fogproof, and shockproof. Nitrogen-purged scopes can help prevent internal fogging when temperatures change. Scratch-resistant lenses are another useful feature because they provide additional protection during transportation and field use.
6. Turret Adjustments and Return-to-Zero
If you frequently adjust elevation and windage, pay close attention to the turret system. Features such as 0.1 MIL or 1/4-MOA adjustments, locking turrets, resettable turrets, and return-to-zero systems can make the scope easier to use. A return-to-zero system is particularly useful when making adjustments for different shooting distances and then returning to the original zero.
7. Weight and Overall Size
The scope should complement the Ruger .308 rather than making the rifle unnecessarily heavy. A large 3-18x50mm scope may provide excellent versatility but can weigh considerably more than a compact 3-9x40mm hunting optic. If you will carry the rifle over long distances, a lighter scope may be preferable. If the rifle will primarily be used from a fixed shooting position, additional weight may be less important.
8. Compatibility With the Ruger .308
Finally, always verify that the scope is actually intended for .308 Winchester or is otherwise suitable for the rifle. This is especially important when dealing with specialized ballistic reticles. For example, the Hawke crossbow scope discussed above uses aiming references calibrated for crossbow speeds, making it inappropriate for a Ruger .308 despite its impressive optical features. Similarly, the previously discussed Leupold Model #177910 was identified as a 350 Legend configuration, so the exact model should be verified before recommending it for a .308.
Frequents Asked Questions on Best Scope for Ruger 308
1. What magnification is best for a Ruger .308?
For general hunting, a 3-9×40 scope is a popular all-around choice because it provides a useful field of view at lower magnification while offering enough power for typical medium-range shots. For longer-range target shooting, a 3-15x or 3-18x scope can provide additional magnification.
2. Is a BDC reticle good for a Ruger .308?
Yes. A BDC reticle can provide convenient holdover references for different distances, but the markings should be verified with your particular .308 rifle and ammunition because actual trajectory varies. The Ruger American has been paired with optics using BDC reticles, including a 3-9×40 configuration.
3. Should I choose a 40mm or 50mm objective lens for a Ruger .308?
A 40mm objective is generally a good balance of light transmission, size, and weight for a hunting rifle. A 50mm objective can provide more light-gathering capability, particularly in dim conditions, but it usually makes the scope larger and heavier. For a lightweight Ruger .308 hunting setup, a quality 3-9×40 can therefore be a very practical choice.
Conclusion
Choosing the Best Scope for Ruger .308 comes down to finding an optic that offers the right balance of magnification, optical clarity, reticle design, durability, and ease of adjustment. A good scope should provide a clear sight picture in different lighting and weather conditions while remaining reliable under recoil and comfortable to carry in the field. Whether you prefer a simple 3-9x scope for general hunting or a higher-magnification option for longer-range shooting, focusing on your shooting distance, intended use, and rifle compatibility will help you select a dependable optic that meets your needs.
