Nikon M-308 Scope Review

I recently purchased the Nikon M-308 scope for my AR10 and decided to write a review. I figured this could help other people decide if they wanted to purchase this scope for their gun. First I'll give you some of the information that they tell you on the Amazon product description.

>>>View Nikon M-308 4-16x42mm Riflescope w/ BDC 800 Reticle here<<<

The M-308 is designed for rifles capable of long range accuracy. It's supposed to give you "extreme sighting speed" and "superior long range accuracy."

You can get it with either the BDC 800 reticle or the Nikoplex reticle and Rapid Action Turret. These are calibrated for the .308 Win/7.62 NATO Match round with 168gr. HPBT bullet. The scope is ideal for AR10 rifles because of its high magnification range zoom.

The dial-in version of the reticle is pretty easy. All you need to do is figure out your distance to your target, rotate the elevation turret to match the distance, center the crosshair on the target, and fire!

Now for my personal experience with the scope: the first thing I noticed when I took the scope out of the box was that it was put together with some pretty quality workmanship. I knew that Nikon makes a good camera and that most of their scopes are pretty good quality, but I was still pleasantly surprised by the overall feel and look of the scope.

The scope is just one main piece, which I think helps to minimize the weight of it. This is definitely helpful when you're lugging your gun around for miles or trying to hold it still for a little while.

When I looked out of the 4 inch eye box, the optics seemed pretty clear and very bright. I definitely liked the initial look that I saw through the lens. The product is advertised to have a "bright, sharp, incredibly flat sight picture and light transmission up to its theoretical maximum 95-Percent."

The one thing that bothered me about the scope was the parallax and the eye relief. I liked the parallax adjustment knob, but the eye relief was a bit close after the 16x zoom. I didn't mind it up to 12x, but after that it definitely could use some improvement.

If you're just getting into long range rifle shooting and don't need anything crazy, you're not going to have a problem. But I would recommend a bi-pod if you want consistent shot placement at 200 yards or more.

I have come to appreciate a clean, uncluttered reticle. The Nikon M-308 did not disappoint me here. The only problem I have with the reticle is that it only works in 50 yard increments. I really like the positive click reticle adjustments. The settings seem to maintain very well even after recoil.

One of the best things about this scope is that it comes with a pretty good mount. This one comes with an M-308 XR Scope Mount. Some scopes don't even come with mounts, and you have to find one that works for it. That can definitely be a pain in the ass. Just so you know, there is a mistake on the Amazon product description. It says it comes with an M-223 XR Scope Mount, but it is really a 308.

The mount is one piece (which is definitely a first for me). It's pretty easy to mount, although I have heard a few complaints about the threads being stripped on other people's scope mounts. Personally, I didn't have a problem with this.

The mount comes with a built-in 20 MOA slope, which adds 20 minutes of angle elevation to the whole scope system. This feature allows a shooter to do some extreme long range shooting. Just remember that, like I said before, you might need to use a bi-pod when you go beyond 200 yards.

Another thing that this scope comes with is an anti-reflective device (ARD), or, as some people call them, sunshades. Again, a lot of scopes don't come with an ARD. In my book, this helps with cost and convenience. The one that it comes with gets the job done.

The Nikon M-308 also comes with lens caps, so you don't have to worry about finding the right size caps for the job.

It also comes with a pretty nice cleaning cloth. Don't forget your cleaning cloth when you're out hunting. I can't tell you how many times I've been out on a muddy or rainy day. I go to clean off my scope lens and I can't find my cleaning cloth. Now I have to use my shirt or my jacket, which definitely doesn't do the job!

The instruction book that comes with the scope is a really good one. It's very clear and complete. And the information it gives you is actually helpful. What a concept! If you want to get into the technical side of shooting, I heard there is an app you can use that will compute the exact ballistics for you.

There is one more downside to this scope for us hardworking Americans. It is assembled in the Philippines. Of course, we want everything to be made in America, but it is what it is (and probably cheaper because of it).

I consider the pricing for the Nikon M-308 scope to be in the mid-range category. It is definitely priced well because it is way better than any low-end "tactical" scope. Actually, I think it is a very good scope for the money that you need to shell out for it.

You definitely get maximum strength and durability for the price that you pay. And as a bonus, it comes with a life-time warranty. You really can't beat that. You also might be able to find some coupons or rebates if you're looking for a deal.


All in all, I'm pretty happy with my purchase. I would definitely recommend the Nikon M-308 scope for people who want to use it for recreation or hunting. Unless you want to get something really cheaply made that doesn't work well, or you want to spend a fortune on the best scope on the market, this is the "range" that you should be shooting for when it comes to scopes.
