## Description

Review: Simple and effective - If you’re looking for a holosun, buy a holosun. UTG makes very good products and this is no different. It doesn’t have a shake awake capability so I wouldn’t use this on a concealed carry gun, but it is built solid and sturdy. I have it on an AR-9 and it holds a zero very well and works as I expected it to. The battery is located underneath the sight base so it requires you to remove the sight to change it. The tolerances are pretty snug though so it shouldn’t be off very much at all when you put it back on.
Review: 10/10 Would recommend - Easy to install, good brightness setting on it, nice size to it, and feels like fairly good quality given the affordability.

Easy to install, good brightness setting on it, nice size to it, and feels like fairly good quality given the affordability.

### ⭐⭐⭐⭐ Good budget red dot option.
*by A***O on August 23, 2024*

It works, it works nearly the same as an RMR Type 1/2; battery on the bottom, no frills. 4 MOA is good enough for defensive or just general use. I put this dot on non serious guns that I just want a dot on. They hold zero and do not flicker under use. 4 stars until further testing occurs.
