Questions & Answers
Which UTG RMR to Picatinny mount Will co witness with these? The 1/3 co witness or the absolute co witness? Expert Answer

The UTG Pro AR Flip-up Rear Sight is set at an absolute co-witness height. So you would need to use the absolute co-witness RMR mount to co-witness this sight with your optic.

The Utg rear site lays flat, locks in position and works. It’s made of metal and holds zero; no frills no BS. I also bought the matching front site and just like the rear it’s simple, robust enough, accurate enough but also quite affordable.
