It is a little funny with a cord coming from below the mag well. I agree the cord could get hang up or be hard to fish through attached to the bolt block area.I am looking into a way to add cord that is a bit cleaner. I could add some geometry in the exposed bolt block area but it may hang up as the MagFlag as its installed or removed. I still like it to drop free with ease.
Is the length of bolt from bolt arm to nose relatively the same length (+/- 1/4")? If I made a nice cord vs elastic would it work across most makes of actions?
