Hands-On: Nikon M-308 Review (2025 Long-Term Test) | Hunting Mark Overview
The Nikon M-308 is a riflescope specifically engineered for the .308 Winchester/7.62x51mm NATO cartridge. Its main purpose is to eliminate the guesswork in long-range shooting by incorporating a Bullet Drop Compensating (BDC) reticle that is pre-calibrated for the trajectory of popular .308 loads. This means the holdover points on the reticle correspond to specific distances, allowing for rapid and accurate shots without dialing adjustments. It is a tool designed for efficiency and speed in dynamic shooting environments.
This product is ideally suited for hunters pursuing medium to large game, as well as tactical-style shooters who operate with a .308 platform. It is not a benchrest scope for extreme long-range precision shooting, but rather a rugged, field-ready optic for those who need to make a clean, ethical shot when it counts. Key specifications include a 4-16x magnification range, a 42mm objective lens, and a side-focus parallax adjustment, all housed in a sealed, nitrogen-filled tube that is both fog-proof and waterproof.
Throughout my testing, the one-piece tube construction provided a solid foundation, maintaining zero consistently even after being transported over rough terrain. The turrets offer tactile and audible clicks, giving positive feedback for any adjustments you do need to make. It strikes a balance between sophisticated functionality and straightforward operation.

Key Features & Performance
Living with this scope for an extended period allowed me to test its key features under a variety of conditions, from early morning fog to bright, sunny afternoons. The performance has been consistently impressive, validating its design philosophy.
Optical Clarity and Light Transmission
The heart of any scope is its glass, and Nikon’s expertise shines here. The fully multi-coated lenses provide a bright, sharp image with excellent color fidelity. Even in low-light conditions during dawn and dusk, the image remained clear enough for positive target identification. I never felt like I was struggling to see through a dim or hazy image. The resolution is sharp across most of the field of view, with only minor softening at the very edges at higher magnifications, which is common in this category.
BDC 800 Reticle
This is the scope’s party piece. The BDC 800 reticle is simple and uncluttered, with circles marking the drop for a 168-grain .308 bullet out to 800 yards. In practice, I found it incredibly intuitive. On a hunt for prairie dogs, the reticle allowed for rapid engagement of targets at varying distances without taking my eye off the scope to adjust turrets. The circles are thin enough not to obscure small targets but bold enough to pick up quickly. It is important to note that while calibrated for 168gr, you can use Nikon’s Spot On Ballistic Program to match the reticle to your specific load.
Durability and Construction
The one-piece aircraft-grade aluminum body is built to last. I subjected the scope to the recoil of a .308 for hundreds of rounds, and it never lost zero. It has also endured bumps, drops from a shooting rest, and exposure to rain. The seals remained intact, and the nitrogen purging prevented any internal fogging, even when moving from a warm vehicle into a cold, damp field. The anodized finish has held up well, showing only minor wear at the mounting points.
Turret Performance and Ergonomics
The turrets are a highlight. They offer a crisp, positive click with no ambiguity. The resettable zero feature is a nice touch, allowing you to easily return to your baseline after making elevation or windage corrections. The side parallax adjustment knob is smooth and easy to reach, helping to eliminate parallax error for more precise shots. The magnification ring also turns smoothly, with clear markings that are easy to read by feel alone.

Final Verdict
After this long-term evaluation, the Nikon M-308 has proven to be a highly effective and reliable optic. It does exactly what it was designed to do with minimal fuss. For the shooter who wants a dedicated scope for their .308 rifle, it is an option I can wholeheartedly recommend.
Pros
- The .308-specific BDC reticle is a game-changer for fast, medium-range shots.
- Optical quality is superb for the price, providing a bright and clear sight picture.
- Built like a tank, withstanding significant recoil and rough field conditions without issue.
- User-friendly controls and ergonomics make it easy to operate under pressure.
Cons
- The specialized BDC reticle is less versatile for those who shoot a variety of calibers.
- The 4-16x magnification may be limiting for shooters who regularly engage targets beyond 600 yards.
- As a second focal plane scope, the reticle subtensions are only accurate at one magnification setting.
I recommend this product for hunters and recreational shooters who primarily use a .308 rifle and want a scope that simplifies longer shots. It is perfect for deer, elk, and boar hunting where shots can vary from 100 to 400 yards. However, if you are a long-range competitive shooter who needs to dial for every shot or someone who frequently switches between different rifle calibers, a more general-purpose scope with a standard Mil-Dot or MOA reticle might be a better fit.
What Customers Say About This Product
User experiences with the Nikon M-308 often echo the findings from my long-term test, highlighting its practical performance in real-world situations.

David L. “After sighting it in with my preferred 168gr load, I was hitting steel consistently out to 500 yards using the reticle circles. It makes shooting at unknown distances much less complicated.”
Jake “Trip” Wilson “I was skeptical about a dedicated .308 scope, but it works. The only downside is I now want one for my other rifles. It’s that good.”
