Frequently Asked Questions

What is a reflex sight and how is it different from a red dot?

A reflex sight is a type of optical aiming device that uses a lens and light source to project an aiming point onto the lens—in this case, a 4.0 MOA red dot. Unlike magnified scopes, reflex sights are parallax-free at typical shooting distances, offer unlimited eye relief, and allow both eyes open shooting, making them fast for target acquisition and ideal for tactical, hunting, and competitive use.

Can I install the battery without removing the sight from my rifle?

Yes. The UTG OP3 Micro SLS features a side-loading sensor design that allows you to install or replace the battery without unmounting the optic, preserving your zero and eliminating the need to re-bore your rifle.

What does the 4.0 MOA dot size mean?

MOA stands for minute of angle. A 4.0 MOA dot subtends 4 inches of width at 100 yards, making it large enough for quick target identification and fast transitions, while still providing sufficient precision for accurate aiming at typical defensive and hunting ranges.
