Night Fision Optics Ready Stealth Lower 1/3rd Night Sight Set Review

First Impressions of Night Fision Optics Ready Stealth Lower 1/3rd Night Sight Set

The Night Fision Optics Ready Stealth Lower 1/3rd Night Sight Set promises a streamlined approach to co-witnessing iron sights with slide-mounted red dots, and Night Fision is known for its tritium illumination technology. Unlike some competitors who simply repurpose suppressor-height sights, Night Fision has engineered these sights specifically for a lower 1/3 co-witness, optimizing the sight picture for red dot users. This immediately piqued my interest, as I’ve struggled with the bulkiness of traditional suppressor-height sights obstructing my optic window.

My journey to these sights began with frustration; I recently added a red dot to my Glock 19 and hated the cluttered sight picture using standard suppressor height sights. I wanted a backup sight solution that wouldn’t dominate my field of view through the optic. Upon unboxing, the Night Fision sights felt solid and well-machined, made of what appears to be quality steel. The black nitride finish gave them a sleek, durable look, and the tritium vials glowed brightly, even in dim lighting.

Compared to Ameriglo’s suppressor height sights, which I’ve used extensively, the Night Fision set seemed less obtrusive. I also considered Trijicon’s Bright & Tough night sights, but I was specifically looking for a lower 1/3 co-witness option. Ultimately, the promise of a cleaner optic window and Night Fision’s reputation for bright tritium illumination won me over. I was definitely excited – these sights seemed to offer the perfect balance of backup functionality and minimal optic obstruction.

Real-World Testing: Putting Night Fision Optics Ready Stealth Lower 1/3rd Night Sight Set to the Test

First Use Experience

I tested the Night Fision Optics Ready Stealth Lower 1/3rd Night Sight Set at an indoor shooting range initially, focusing on transitioning between the red dot and iron sights. The lighting conditions varied from bright to dimly lit, simulating different environments. The sights were easy to acquire, even with the red dot active, and the lower 1/3 co-witness proved to be exactly as advertised.

The transition was smooth, and the tritium inserts were visible even in bright light due to the daylight fluorescing ring. The serrated rear sight helped to reduce glare, and I appreciated this feature immediately. There were no initial issues; the sights performed flawlessly during the first range session.

Extended Use & Reliability

After several months of regular use, the Night Fision Optics Ready Stealth Lower 1/3rd Night Sight Set has held up remarkably well. I’ve put them through various drills, including rapid target acquisition and malfunction clearing. The black nitride finish shows no signs of wear, and the tritium inserts remain consistently bright.

Maintenance is simple; I just wipe them down with a lightly oiled cloth after each range session. Compared to my previous experiences with painted sights that would chip or fade, the Night Fision sights are a significant improvement. These sights have exceeded my expectations in both durability and functionality.
