The "feel" of the weapon locking back is a range only deal in my opinion... unless you're fighting from long range behind safe cover.
I've shot moderately stressful range drills in class (with yelling commands and moving, etc.) and you can't feel the bolt lock back for sh1t when it's so chaotic.... let alone A REAL FIGHT FOR YOU LIFE situation.
You can see the sight pic difference on a pistol, but under extreme stress, I wouldn't bank on it.
