If i could give this zero stars i would - SIG SAUER OPMOD ROMEOZero Reflex Red Dot Sight

I bought this as I though Sig would make a decent budget optic, but I was completely wrong. First off, the red dot has an issue where it can get stuck in the upper right of the window and no amount adjusting will change this. I learned that after calling into Sig and getting one of the most rude customer service representatives I have ever interacted with, who then hung up on me. After this I followed the instructions from Sig, got the adjustments working again, and lo and behold the optic seized again. After this I decided to take the optic off, but the screws they used have red threadlock on them so I have to take it to a gunsmith. Don't waste your money, just buy a better optic.
