I recently picked up a Ruger american in .308. I wanted something for cheap that I could mess around with long range shooting out to 200 yards for now. I fired 20 rounds at a 50 yard indoor range but I'm having a hard time holding it comfortably. I have always fired m16/m4/ar15 both in the military and civilian. With adjustable stock and my nose on the charging handle I am dead on. I just can't seem to get a good check weld and reference point comfortably on this rifle. If I'm comfortable my eye is too close to the scope. If I back up from the scope the but stock is more on my arm than shoulder. I'm getting frustrated. If I close my eyes and rest comfortable the scope is too high. If I adjust to see out the scope i have to awkwardly hold my neck at a strange angle. My scope is already mounted as far forward as I can get it (redfirld revenge 3x9 40) I might try a check pad. Any other suggestions or am I just over used to an AR platform?
