I have the Trigicon MRO on my Chiappa 1892 .44 Rem Mag. I love it. Big aperture, fast target acquisition. The only issue I might have is it's so big it looks like I put a periscope on that beautiful old west style rifle. 😂 That and the riser still partially blocks the ghost ring. I'm going to put it on my Ruger PC9 carbine and get a smaller one for the .44 with a better riser.
