Published on November 16, 2025
Duration: 27:13

This video provides an in-depth review and testing of the SMS Trinity IR laser, focusing on its performance as a market disruptor in the IR device space. The instructor, Kyle from 4MR Ranch, details his testing methodology, including zero retention tests on 5.56 and .308 platforms, and night vision comparisons. He highlights the unit's budget-friendly price point and its three-in-one functionality (visible laser, IR laser, IR illuminator), while also discussing minor ergonomic nitpicks and potential quality control variations.

Quick Summary

The SMS Trinity IR laser is a budget-friendly, 3-in-1 device (visible laser, IR laser, IR illuminator) disrupting the market at $350. It offers strong IR illumination, FDA compliance via Vixel technology, and decent zero retention, though minor ergonomic issues and potential quality control variations exist.

Frequently Asked Questions

What is the SMS Trinity IR laser and why is it considered a market disruptor?

The SMS Trinity is a 3-in-1 IR laser device featuring a visible laser, IR laser, and IR illuminator. It's considered a market disruptor due to its aggressive $350 price point, offering significant value compared to competitors costing nearly three times as much, while still providing strong illumination and multiple functionalities.

How does the SMS Trinity perform in terms of zero retention under recoil?

Testing on a SCAR 16 with 5.56 showed some diode drift (0.2 MOA vertical, 1 MOA horizontal) after 250 rounds. However, a second unit showed virtually no drift. On a SCAR 17 with .308, after an initial zero shift due to mounting issues, the zero was retained for approximately 60 rounds, with diodes remaining stable over 180 total rounds across both platforms.

What are the main ergonomic nitpicks of the SMS Trinity IR laser?

The primary nitpicks include the illumination divergence slider feeling too similar to the fire button, making it hard to distinguish in the dark. The adjustment screws require a tiny screwdriver, which is inconvenient for on-the-fly adjustments. Additionally, the selector dial lacks tactile feedback, making it easy to miss positions in low-light conditions.

How does the SMS Trinity's IR illuminator compare to other devices like the DBAL-D2 and Hollow Sun Iris?

The SMS Trinity's IR illuminator is described as 'spicy' and very powerful, capable of illuminating targets out to 500 yards. While it can produce artifacts, it's generally considered cleaner than the SMS HFXC and comparable or better than the DBAL-D2 in terms of intensity and range, though the Hollow Sun Iris may offer a more refined beam.
