Nikon M-308 4-16×42 SF Review

The .308 Winchester has had a great military career and these days it’s become one of America’s favorite sporting and competition cartridges, as well. Of course, the Nikon M-308 4-16×42 SF(View on Amazon.com) is popular for good reason. With the right choice of powder the .308 can match the much longer 30-06 in performance, and thanks to the improvements that have occurred over the years the .308 outperforms the 30-06’s original specs. Throw in a steady supply of surplus ammo for practice and surplus brass for reloading and the .308 becomes attractive package. But what about finding a optic to go with your new rifle chambered in .308? Whether you own a traditional hunting rifle or an AR-10, finding the right optic compatible with your rifle can be a challenge. Thanks to Nikon – they have helped solve this problem at a pretty reasonable price as well.

Nikon has gone a long way in solving this dilemma for .308 enthusiasts with the introduction of the M-308. This model builds off of the M-223 platform and has all of the built-in dependability, high light transmission and quality that people have come to expect from Nikon products, but with a few features added for the .308 Winchester/7.62×51 NATO cartridge.

For starters the M-308 features Nikon’s Eye Box Technology which allows for no less than four inches of noncritical eye relief, a feature that can come in handy when it comes to mounting your optics on some AR-10 rifles. Nikon has also equipped this model with rapid action turrets which allow the point of aim to be adjusted from 100 to 800 yards through only a single revolution. The adjustable turrets are backed up by a bullet drop compensation system based on the reticle that features hold off marks out to 800 yards. Finally, this scope includes a 20 MOA inclined mount to ensure there will be plenty of adjustment in the overall package for long-range shooting. The addition of an inclined mount such as this is never a bad idea with the .308 if bullets in the 200gr weight range are utilized.

While the M-308 isn’t the perfect optic for every .308 Winchester-chambered rifle, it’s a good choice for a lot of them. The combination of the adjustable turrets coupled with a bullet drop compensation system allows for enough flexibility for a wide variety of loads, and this model’s ample eye relief means it can be mounted on just about any type of rifle, although AR-10 owners will find it suitable. Nikon has a full lifetime warranty on this version.
