How to Choose the Best Long-Range Scope for AR-10 308
Here are some important factors to consider when looking for the best scope for long-range shooting with a 308.
Material
Scopes for long-range shooting with a 308 made of aluminum alloy, aircraft-grade aluminum, or any other high-quality materials are the best. These premium-grade materials are not only durable but also shock and impact resistant. Besides, scopes made with aluminum are mostly rustproof, so you can use them in any weather condition.
Weatherproof
Different weather conditions can strike when you least expect them, so getting a scope capable of standing in all weather conditions is very important. Scopes sealed with strong O-rings and nitrogen/argon purged are more sought after as they offer reliable waterproof, and fog proof performance. With such a scope, you can shoot confidently, even in bad weather conditions.
Magnification
For long-range shooting with a 308, a medium to high-magnification scope is important. Typically, a variable power scope with more than 12x magnification will help you make long-range shots more accurately. A variable power scope with a wide magnification will also give you the versatility to engage targets across different distances.
Objective Lens
The size of the objective lens determines how much light a scope collects. The scope must gather as much light as possible for long-range shooting for clear image generation. This calls for a scope that has a large objective lens diameter of at least 40mm
Lens Quality
A scope that provides tack and sharp image clarity will make your long-range shooting expedition successful and more fun. To achieve this, the scope should have premium optics, preferably HD, ED, or better. The scope should also have fully multi-coated/ fully-coated lenses for bright and vivid image generation.
FAQs
What Magnification Range Do I Need for Long-Range Shooting with an AR-10 in .308?
Typically, a scope with a variable magnification range between 4x and 16x or 6x and 24x is suitable for long-range shooting with an AR-10 chambered in .308. The ideal range depends on your shooting style and the distances you intend to shoot.
What is a good scope to put on a 308?
A good scope for a 308 should have a decent magnification power to cover the intended shooting distance. It should also offer long eye relief, high-quality glass, fully multi-coated lenses, a wide field of view, and durable construction.
Does the military use 308?
Yes. The 308 Winchester is one of the cartridges that is commonly used by civilians and as well as the military for medium to long-range shooting.
What’s the Difference Between First Focal Plane (FFP) and Second Focal Plane (SFP) Reticles?
FFP reticles change in size with magnification, allowing for accurate range estimation and holdovers at all magnification levels. SFP reticles remain the same size, so their subtensions are only accurate at one magnification setting (usually the highest).
Conclusion
The 308 cartridge’s popularity has increased in recent years, and numerous scopes are available to best match your AR10 chambered with this cartridge. Focus on getting a scope that fits your hunting style and preference. And remember, whatever your needs are, there is scope for you.
We hope this best long-range scope for AR-10 308 post helped you find the best long-range scope for AR-10 308.
