How far out are you shooting? At any reasonable range, iron sights are fine. If ‘reaching out to touch something’ a scope, sure. Question is, what are you shooting and why. If considering close in shooting (they’re coming after you) good iron sights with a good sight picture is best, quicker target acquisition.
I live in a moderately dense suburban environment. If I’m dealing with a horde of zombies, I’m probably shooting at 50 to 100 yards. Find the EOTech coupled with a 3x magnifier makes that EASY. For closer in work, I’d flip the 3x magnifier to the side. Within 10 yards, I’d just point and shoot — good enough to hit center of mass consistently (say 90% of the time or so). For REALLY close in work, I’d go to my shotgun or katana...
The combo just works really well for me. Other people’s mileage may vary...
The National Match sites on my M1A are just fine.If I can see it,I can shoot at it.
