Buy a romeo5 or an msr - SIG SAUER Romeo7S 1x22mm Compact Red Dot Sights - Reflex

I just received my Romeo7s directly from Sig and compared it to a Romeo5 and there is no noticeable difference in the field of view and it may actually be worse. The Romeo7s has a 22mm objective and the Romeo5 has a 20mm objective and either a 10% increase is not enough of a difference to perceive or they just put a larger objective on the same size tube negating any difference. I expected it to be about halfway between a Romeo5 and my MRO (25mm) but it isn't even close. I can see exactly the same field of view as the Romeo5 although the emitter/emitter housing of the Romeo7s protrudes into the tube more than it does on the Romeo5 obscuring the lower right even more and because the body is much larger than a Romeo5, your peripheral vision is affected more as well. Either get a Romeo5 or go bigger and get an MRO or Primary Arms MD-25 or if you want the AAA compatibility buy a Romeo5-XDR or full-size Romeo7. The 7s offers nothing the others don't.
