Nikko Stirling Diamond 4-16x44mm 34mm Tube Rifle Scope, First Focal Plane Review

What Makes Nikko Stirling Diamond 4-16x44mm 34mm Tube Rifle Scope, First Focal Plane Stand Out?

The Nikko Stirling Diamond 4-16x44mm 34mm Tube Rifle Scope, First Focal Plane is a scope designed for precision shooting, emphasizing long-range capabilities and tactical applications. Built by Nikko Stirling, this scope boasts a 34mm tube for enhanced elevation adjustment, a First Focal Plane (FFP) reticle, and a Half Mil Dot (HMD) reticle for accurate ranging at any magnification. This combination makes it a versatile optic for shooters who demand reliability and precision in varying environments.

I was looking for a scope that would allow me to reliably engage targets at extended ranges, something beyond what my standard 1-6x LPVO could offer. I needed a scope with precise MIL-based adjustments and a reticle that would allow for accurate holdovers regardless of magnification. The Nikko Stirling Diamond 4-16x44mm FFP seemed to tick those boxes, especially given its relatively affordable price point compared to other FFP MIL scopes.

Upon unboxing, the scope felt substantial. The matte black finish appeared durable, and the turrets had a satisfying click to them. The weight, at 680g, felt appropriate for a scope of this size and specification, suggesting a robust construction.

I considered the Vortex Viper PST Gen II 3-15×44 and the Primary Arms GLx 4-16×44, both popular choices in this category. I chose the Nikko Stirling mainly due to the combination of the 34mm tube (promising greater elevation adjustment) and the HMD reticle, which I found less cluttered than some other MIL-dot designs. The price was also a factor, edging out the Vortex slightly.

My initial impression was one of cautious optimism. The scope seemed well-built, but the proof would be in its performance on the range. I was eager to see if the adjustments were precise, the glass clear, and the FFP reticle truly beneficial at different magnifications.

Real-World Testing: Putting Nikko Stirling Diamond 4-16x44mm 34mm Tube Rifle Scope, First Focal Plane to the Test

First Use Experience

I initially tested the Nikko Stirling Diamond 4-16x44mm FFP at an outdoor shooting range, focusing on targets ranging from 100 to 600 yards. The weather was clear and sunny, providing ideal conditions for evaluating the scope’s optical clarity and adjustment accuracy. I mounted the scope on my AR-15 chambered in 6.5 Grendel, a platform known for its long-range capabilities.

The scope performed admirably in these conditions. The turrets were easy to adjust, with distinct and tactile clicks that gave confidence in each adjustment. The image was clear and bright, and the parallax adjustment on the saddle allowed me to eliminate parallax at all tested distances. The first-time use was relatively smooth, and I only needed a few shots to zero the rifle at 100 yards.

There were no immediate issues, but I noticed that the illumination, while functional, wasn’t particularly bright in direct sunlight. This made the reticle slightly harder to see against bright targets.

Extended Use & Reliability

After several months of use, the Nikko Stirling has proven to be a reliable optic. I’ve used it in varying conditions, from sunny days at the range to overcast days during a hunting trip. While it hasn’t seen extreme environments, it’s been exposed to light rain and dusty conditions.

The scope has held zero consistently, and there are no signs of wear and tear beyond minor cosmetic blemishes. The matte finish seems durable, and the turrets still provide the same positive clicks as when new. Cleaning the lenses is straightforward with a microfiber cloth and lens cleaning solution.

Compared to my previous experiences with budget optics, the Nikko Stirling Diamond 4-16x44mm noticeably outperforms them in terms of optical clarity, adjustment precision, and overall build quality. It doesn’t quite match the performance of high-end optics, but it offers excellent value for its price. It has definitely improved my confidence in my ability to make accurate shots at longer ranges.
