Nightforce 2.5-10x24 NXS
![]()
With 3-Gun matches gaining popularity on a weekly basis, the optics used in the matches are expanding in to new areas as well. It used to be that if you wanted a magnified optic on your rifle you used a traditional 3x9 scope, and if you wanted a reflex type sight, you went with a red dot of some flavor. The problem came in after some of those evil match directors started adding 300+ yard targets to the stages, and very quickly the need for a dual-role optic was seen. Something that can handle CQB targets, as well as, give you the edge to reach out and touch something. I have been running a 1-4x24 optic for quite a while on my 3-Gun rifle, but my eyesight isn't the best, so additional magnification wouldn't bother me a bit.
The Nightforce NXS 2.5-10x24 is the larger of the two compact scopes Nightforce has recently brought to the market. Boasting the same glass etched reticle and 30mm main tube as the larger NXS scopes, the 2.5-10x24 is geared towards tactical competitions, military and law enforcement users, and big game hunters. On paper it seemed the 2.5-10x24 would accomplish everything that I was wanting in a mid-range rifle scope, but having never shot it, I was a little leery about how it would hold up to the abuse I typically subject my gear to. My only experience shooting Nightforce glass was on a 50 BMG rifle in Colorado last yr. Even though I didn't get much time on it, I knew it was a quality scope. So when Nightforce offered to let me review the 2.5-10x24, I jumped at the opportunity.
The first time I used the scope, I was immediately impressed by its brightness and optical clarity despite the 24mm objective diameter. Shooting in less than ideal conditions, the scope never missed a beat. The weather outside was extremely overcast, foggy, and cold but I was still able to see my target and reticle clearly. Once I was able to get out to the range in good weather, the scope really came to life. The reticle was sharp and crisp, and the glass was some of the best I have ever used. The one thing that I liked the most was that the reticle didn't "blur out" like some of the traditional reticles do. I don't know if it is because I wear contacts or what, but with some scopes I have a problem with the reticle "blurring out", requiring me to look off target, then get back on the reticle to have a clear sight picture. I have not found this to be a problem with the 2.5-10x24 NXS.
Before I used the scope for the first time at a local 3-Gun match, I was a little concerned that the 2.5x setting would be a problem for me on close targets. I had used 1X or reflex scopes for so long, that I wondered how seeing things at 2.5x would affect my ability to engage close targets and transition to the array of targets. It was different at first, but I quickly adjusted to it, and hammered on like normal. This is the same principle that ACOG users employ to use engage close targets. Its a little tricky at first, but once you put some rounds down range you pick up the concept pretty quickly. Engaging distant targets are no problem either. Dial up your desired magnification, and use the NXS like you would any other magnified scope. The field of view is reduced at higher magnification compared to scopes with larger objectives, but I did not feel this was a major concern unless you were in an overwatch position. The illumination was bright enough to see in full sunlight, even if I didn't care for the way the illumination controls were setup.
The size of the scope, or lack thereof, really impressed me for what it provides. It provides enough eye relief to use on an AR-15, but not so much that it requires a special mounting setup. This scope may be smaller than the majority of the scopes on the market, but dial it up to 10x and you will swear your looking through a larger scope. Nightforce also offers their Unimount that attaches to any Picatinny rail, that does a wonderful job of placing the scope in the right position for the shooter, while providing a 20MOA base to make use of the 100 MOA elevation and windage that the 2.5-10x24 is equipped with.
After shooting the 2.5-10x24 on my AR-15 I wish I would have had more time to set it up on a bolt gun and compare it on that platform as well. With everything it accomplished on the ![]() AR-15 I see no reason why it would not work great on a bolt gun, or even a double barrel rifle. Being able to engage targets that are up close and personal, then being able to engage targets at well over 1000 yards. Even though it is small, it is still a 10X scope that, in the right hands, is very capable to bring "Death from Afar".
Even though overall I think the scope is great, there are a few things that I would improve on if I could. The battery life is somewhat low, and for people used to ACOG's and Aimpoints this will be an issue. I think this could be solved by adding an auto off feature to the scope. I do need to say that you do not have to have the illumination on to see the reticle in broad daylight. I also was not fond of the illumination controls. Mainly the fact that to get to max illumination, you had to cycle through all the low settings first. Also a off position between each of the illumination settings would be great as well. Also I think there should be an "off" setting past the max setting. That way you are only 1 click away from max brightness when the scope is turned off. I would also like to see a side focus adjustment knob, but I realize that with the way the illumination controls are designed, this may not be physically possible, but it would be nice.
The other aspect that I think drives people away from this scope is the price, and that's not a bad thing. With a street price of approx $1200-1400 (depending on options) it is not cheap, but quality rarely is. I understand why it costs what it does, but most people will balk at their scope costing twice as much as their AR-15. Serious shooters understand that you can't hit what you can't see, and you certainly won't have any problem seeing your target with any of the Nightforce scopes.
I hated to send the scope back to Nightforce because it worked so well. So well in fact, that I purchased a 5.5-22x50 NXS to go on my personal 6.5 Grendel AR-15 SPR. That is how much this scope impressed me. Maybe if I am a good boy Nightforce will let me test one of their other NXS scopes in the near future.
What Nightforce says about their custom Mil-Dot reticle. "Developed by the military, the mil-dot reticle allows the sniper to estimate the range to his target. The mil-dot is now the standard reticle found in law enforcement rifle scopes. The term itself, mil-dot, refers to a trigonometric function called milliradian and a dot, which appears as a series of round shaped reference points located on the reticle. Advanced developments at Nightforce have resulted in the creation of a new style of mil-dot reticle. Rather than the solid dots that obscure most of the target, the Nightforce mil-dot reticle consists of see-through round dots which are placed on the vertical and horizontal cross lines that serve as reference points. In addition, all four posts are also see-through. Because both the dots and posts are clear, the target is no longer obscured. As a result, these features enable the sniper to more accurately estimate the range to his target. The dots are spaced precisely 1 mil apart which represents 3.6 inches at 100 yards at specified power. The mil-dot design is etched on precision multi-coated compound glass. This eliminates breakage and misalignment of the reticle. Because of Nightforce?s illumination technology, the glass etched reticle glows red and can be illuminated at different intensities. This flexibility ensures excellent reticle contrast in low light when illuminated or a well-defined black reticle when not illuminated."
I would like to thank Kyle Brown at Nightforce Optics for trusting me with this review. ~Tim

After using the Nightforce 2.5-10x24 scope for the last couple months in Iraq I can say I am sold. I purchased this scope just before returning from leave and had it mounted in a Larue SPR 1.5 mount with a Trijicon Mini Red Dot mounted on the front ring. This combination was mounted on a 16" HBAR upper. After initial zeroing, I practiced on targets ranging from 15m to 100m using the Trijicon and 100m out to 600m using the Night Force. The overall theme of this scope is quality, from the glass to the construction, to the controls. At 10x the image became slightly distorted but was still very clear with good light collection and pulling back to roughly 8x cleared the minimal distortion.
While the overall impression was excellent I did find a few items for the ultimate scope wish list. Battery life is not horrible but I have been spoiled by my Aimpoints with astounding battery life. I don't really like the lens covers/caps and will have flip ups soon. Any other wish list items would in all likelihood have a negative impact on the size of this compact and very capable optic. In short, for the size and weight this scope is a heavy hitter and a force multiplier particularly when mated with the Larue mount and Trijicon Mini Red Dot. ~ Mike
