ok guys I have a question for the experts.....I have a ARMS 40L on my AR I want to know about the 2 appetures. I know the larger appeture is more for CQB work, and the smaller appeture for everything else. When I use the small appeture my groups(50/100 yrds are tight) when I use the larger appeture I have noticed my groups open significantly and are low and mostly left.........is this normal? and is it because the appetures are not same plane?
I know that ARMS makes 40L same plane model.....and I know that the Troy sights are same plane.....does this make a difference? when I have the appetures back to back the smaller app. sits slightly higher than the larger.....I know most sights are like this......I guess I want to know if the same plane sights show a difference in shot placement between appetures or if both are dead nuts on. I use the larger appeture for 25yrds or closer.....it just seems like those shots are always low and left |
