I wanted to put an RMR on the Benelli M4. I was worried about proper cheek weld on the stock. The low mounting option eliminated this concern. Mounting was simple and zeroing with slugs went ok. There were no clicks when making adjustments and the results didn't appear to follow 1 MOA per line, but using a bracketing technique I was able to walk the rounds to POA=POI. Final test at 100 yards produced satisfactory results. The 3 MOA reticles is easy to see for fast tactical solutions. Its a little too big for trying to be precise as in a hunting situation.
Overall, Trijicon makes quality products and I'm happy with the purchase.
