Duration: 14:01

This review of the SMS Trinity LAM, conducted by Brass Facts over 4000 rounds, critically assesses its performance and value. Despite its budget-friendly $350 price point and inspiration from high-end models like the BE Meyers DAGIR, the review highlights significant drawbacks including a visible laser that fails under recoil and a wandering zero on an AK platform. However, it's deemed a viable option for secondary firearms or beginners seeking better quality than airsoft clones.

Quick Summary

While inspired by high-end units, it suffers from a visible laser failure under recoil and a 2-4 MOA zero shift on AK platforms, requiring frequent re-zeroing.
