Trijicon Tenmile TM2450 4-24x50mm Rifle Scope, 30 mm Tube, Second Focal Plane (SFP) Review

Let’s Talk About Trijicon Tenmile TM2450 4-24x50mm Rifle Scope, 30 mm Tube, Second Focal Plane (SFP)

The Trijicon Tenmile TM2450 4-24x50mm Rifle Scope, 30 mm Tube, Second Focal Plane (SFP) is Trijicon’s offering for those seeking a versatile optic capable of handling everything from mid-range hunting to longer-range precision shooting. This scope boasts a magnification range of 4-24x, a 50mm objective lens for excellent light gathering, and a second focal plane reticle, all within a rugged and durable 30mm tube. It’s designed to be a workhorse, providing clear glass and reliable performance across a variety of shooting disciplines.

As someone who has spent over a decade in the outdoor and tactical gear world, I was looking for a scope that could transition seamlessly between my hunting rifle and my precision AR-10. My older scope, while decent, lacked the clarity and magnification needed for consistent long-range shots, especially in low-light conditions. I wanted something that offered premium glass without breaking the bank, and Trijicon’s reputation for quality and durability made the Tenmile TM2450 a compelling option.

Upon unboxing, the Trijicon Tenmile TM2450 immediately impressed me with its solid build quality. The scope feels robust and well-made, with smooth and precise adjustments on the turrets. The matte black finish is clean and professional, and the overall design is aesthetically pleasing. Compared to some other scopes in this price range, like the Vortex Viper PST Gen II or the Leupold VX-5HD, the Tenmile seemed to strike a better balance between features and ruggedness.

My first impression was definitely excitement. The Trijicon Tenmile TM2450 felt like a substantial upgrade from my previous optic, and I was eager to get it mounted and see how it performed at the range. It promised a level of clarity and precision that I hoped would improve my shooting capabilities.

Real-World Testing: Putting Trijicon Tenmile TM2450 4-24x50mm Rifle Scope, 30 mm Tube, Second Focal Plane (SFP) to the Test

First Use Experience

My first outing with the Trijicon Tenmile TM2450 was at my local shooting range, where I zeroed it on my AR-10 chambered in .308 Winchester. The weather was overcast, but the scope’s light-gathering capabilities were immediately noticeable, providing a bright and clear image even in less-than-ideal conditions. The turrets were easy to adjust, with tactile and audible clicks that allowed for precise zeroing. After getting it dialed in at 100 yards, I stretched it out to 300 and then 600 yards, and the Tenmile performed flawlessly.

I also took it on a weekend hog hunt in central Texas. The conditions were challenging – hot, humid, and dusty. The Trijicon Tenmile TM2450 held up admirably, maintaining its clarity and zero even after being exposed to the elements. The adjustable parallax allowed me to fine-tune the focus for different distances, and the illuminated reticle was a lifesaver during the low-light hours of dawn and dusk.

It took me a few range sessions to fully familiarize myself with the MRAD Ranging reticle. However, once I got the hang of it, it became an invaluable tool for estimating distances and making accurate holdover adjustments. There were no malfunctions or issues during the initial testing phase.

Extended Use & Reliability

After several months of regular use, the Trijicon Tenmile TM2450 has proven to be a reliable and durable optic. I’ve taken it on multiple hunting trips, exposed it to rain and mud, and even subjected it to some minor bumps and scrapes. Despite the abuse, the scope has maintained its zero and continues to provide exceptional clarity.

There are no signs of significant wear and tear. The finish is holding up well, and the turrets still feel smooth and precise. Cleaning the lenses is easy, and the Trijicon lens cloth that was included does a great job of removing smudges and fingerprints.

Compared to my previous scope, a Bushnell Elite Tactical, the Trijicon Tenmile TM2450 is a significant improvement in terms of glass quality, clarity, and overall durability. While the Bushnell was a decent scope for its price point, the Tenmile offers a level of performance that is simply unmatched. It’s allowed me to consistently make longer and more accurate shots, both at the range and in the field.

Breaking Down the Features of Trijicon Tenmile TM2450 4-24x50mm Rifle Scope, 30 mm Tube, Second Focal Plane (SFP)

Specifications

• Objective Lens Diameter: 50 mm. This large objective lens allows for excellent light transmission, providing a bright and clear image even in low-light conditions.
• Magnification: 4 – 24 x. The versatile magnification range makes it suitable for a wide range of shooting applications, from close-quarters hunting to long-range precision shooting.
• Reticle: MRAD Ranging. The MRAD Ranging reticle allows for precise holdover and windage adjustments, making it easier to make accurate shots at longer distances.
• Tube Diameter: 30 mm. The 30mm tube provides a wider range of adjustment compared to smaller tubes, allowing for more precise zeroing and holdover.
• Reticle Focal Plane: Second Focal Plane (SFP). In a second focal plane scope, the reticle size remains constant regardless of the magnification level. This can be beneficial for ranging and holdover at specific magnification settings.
• Exit Pupil: 0.33 – 0.9 in. The exit pupil size affects the brightness of the image seen by the shooter’s eye.
• Illumination Color: Red. The illuminated reticle enhances visibility in low-light conditions, making it easier to acquire targets.
• Field of View, Linear: 28.5 – 4.7 ft at 100 yds. This specification impacts how much area you will see at 100 yards through the scope at different magnifications.
• Eye Relief: 3.1 – 3.8 in. Sufficient eye relief is crucial for comfortable and safe shooting, especially with high-powered rifles.
• Weight: 25.7 oz. While not the lightest scope on the market, the weight is manageable and reflects the scope’s robust build quality.
• Adjustment Click Value: 0.1 Mil Rad. This value represents the amount the point of impact changes per click when adjusting the turrets.
• Adjustment Type: Mil Rad. Using Mil Rad adjustments simplifies ranging and holdover calculations, especially when using a Mil-based reticle.
• Parallax: 10 yds to infinity. The adjustable parallax allows you to fine-tune the focus for different distances, ensuring a crisp and clear image.
• Fully Multi-Coated Lens. This coating reduces glare and improves light transmission for a brighter and clearer image.
• W/E Travel at 100 Yds: 20.4/29.1 Mil Rad. This generous adjustment range offers ample travel for zeroing and making long-range corrections.
• Fabric/Material: 6061-T6 Aluminum. Known for its strength and durability, this aluminum alloy ensures the scope can withstand harsh conditions.

Performance & Functionality

The Trijicon Tenmile TM2450 excels in its primary function: providing a clear and accurate sight picture. The glass quality is excellent, with minimal distortion and exceptional clarity across the entire magnification range. The adjustable parallax is a game-changer, allowing you to fine-tune the focus for different distances, resulting in a crisp and clear image at any range. The MRAD Ranging reticle is intuitive and easy to use, making it simple to estimate distances and make accurate holdover adjustments.

One minor weakness is that the second focal plane reticle means that the subtensions are only accurate at a specific magnification setting (usually the highest). This requires you to either remember the correct magnification or use a ballistic calculator to compensate. However, this is a common characteristic of SFP scopes and is not a significant drawback. The Trijicon Tenmile TM2450 meets and exceeds my expectations in terms of optical performance and functionality.

Design & Ergonomics

The Trijicon Tenmile TM2450 features a rugged and durable design, built to withstand the rigors of field use. The 6061-T6 aluminum construction provides excellent strength and resistance to corrosion, while the matte black finish minimizes glare and reflections. The turrets are well-designed and easy to grip, even with gloved hands, and the tactile and audible clicks provide positive feedback when making adjustments.

The scope is relatively heavy, but the weight is well-distributed and doesn’t feel overly cumbersome. The eyepiece is comfortable and easy to adjust, and the included lens caps provide excellent protection for the glass. There is a slight learning curve associated with using the MRAD Ranging reticle, but Trijicon provides clear and concise instructions that make it easy to master.

Durability & Maintenance

The Trijicon Tenmile TM2450 is built to last. The rugged construction and high-quality materials ensure that it can withstand years of use and abuse. It is fully waterproof and fogproof, making it suitable for use in a wide range of environmental conditions.

Maintenance is simple and straightforward. Cleaning the lenses with a soft cloth is all that’s typically required, and the Trijicon lens cloth that was included is perfect for this purpose. The scope is also backed by Trijicon’s legendary warranty, providing peace of mind knowing that it’s protected against defects in materials and workmanship.

Accessories and Customization Options

The Trijicon Tenmile TM2450 comes with a few basic accessories, including lens caps, a lens cloth, and an owner’s manual. There are no included mounting rings, so you’ll need to purchase those separately. However, the scope is compatible with any standard 30mm scope rings.

There are no real “customization” options per se, but the scope is designed to work seamlessly with a variety of aftermarket accessories, such as bubble levels, throw levers, and sunshades. I’ve personally added a throw lever to mine, which makes it much easier to adjust the magnification quickly and efficiently.
