I'm with RC Christian. I love the AR with the EoTech and the magnifier.
Use to be good out to 300yrds with an open sight but the eyes just dont have it anymore.
I practice by shooting golf balls at 100 yrds with the .270 and hit em more times then not with a scope. Not off hand mind you,but with a rest.
Pistols? Not so much,I've always been into long guns and I just recently got into pistols so I'm still working on technique.
I've always been a both eyes open shooter,something I learned shooting shotguns at an early age. This should help me with my pistol shooting.
