I've noticed in the AR pic thread that people have their grips either mounted towards the business end of the barrel or around the middle position of the barrel. What I would like to know is what position works for you and why it does. Is a grip that is further forward allow for a "thumbs forward" grip? Does that help you with accuracy? Does a closer grip allow for faster manipulations? I feel like I can maintain a more stable hold on my rifle with the grip being further forward as it seems to add a tighter hold, at the same time, I notice my arm that is holding the grip in the further out position becoming fatigued quickly which i don't like. Thanks for all the responses!
