Gabe suarez stole the RMR idea from an earlier instructor Jim Grover/ Kelly McCann
I like the battery powered RMR and the larger dot 6 to 8 MOA as its easier to find
It took me several days of practice to pick up the sights and red dot quickly.... At first it was slower for me.... especially up close where you don't need sights to keep rounds on paper 5-10
At 15 yards + the ability, with older eyes, to keep everything in the head shot box is great
The RMR does not make up for any lack of skill.... It does help with aging eyes... in my book
