- Issue: The optic body is made with 6061 T6 aluminum. It's not the strongest body, and the screw threads can easily strip when using steel screws if torqued too hard
- Solution: Do not hand tight the screw. Always use a torque wrench to set each T10 torx mounting screw to 8 in pounds
Real Avid Smart Torq Wrench is highly recommended for mounting optics correctly
- Issue: Most people have complained about the low battery timing and poor battery contact. There might be a problem with the battery’s quality.
- Solution: Replacing the old battery with a new one can resolve the issue of poor battery performance.
Reticle Brightness Level Is Not Enough
- Issue: Many shooters face the problem of astigmatism regardless. However, the brightness level isn't enough under some bright daylight conditions. The dot appears dimmer if wearing polarized sunglasses.
- Solution: If the lighting condition is too bright, you have to swap to another optic with much more dot brightness. Or use with a red dot magnifier
- Issue: Some shooters have complained about the Sig Sauer Romeo 5's durability. It can get damaged from a short drop or get scratched easily.
- Solution: Handle the optic with care and avoid excessive abuse. The ROMEO 5 is not marketed to be physically abused like the Aimpoint Micro
- Issue: Some users received a low-quality mount with their Sig Sauer Romeo 5. A poor-quality mount can affect zero retention. This problem can easily be solved.
- Solution: Use a high end Aimpoint Micro mount like the Scalarworks LEAP, Geissele Aimpoint mount or LaRue Tactical mount.
Sudden Dot Failure
- Issue: Some shooters on online forums have reported sudden dot failure. Majority of users have not
- Solution: Replace the battery and turn down the dot brightness when transporting to and from the range. Tighten the battery cap
Opposite Turret Adjustment
- Issue: Some shooters report that the turret adjustment move the dot in the opposite direction of the point of aim
- Solution: The direction label on the turret represents the direction of the shot group, not the reticle. This is not a problem with the turret, it's designed that way.
MOTAC (Motion-activated illumination)
- Issue: The optic remains on when transporting to and from the range, and the optic is always on
- Solution: If you receive a faulty product, the company should replace it under warranty. Otherwise, turn down the dot brightness to save battery
Overall the Sig ROMEO 5 is a great red dot sight for budget users. Even though there are some problems, but they aren't big problems that prevent it from working. For more, please check out our ROMEO 5 review
