What a bunch of smart guys!
It is a legitimate tip, you get someone else to place the dime for you, duh.
It is really used for new shooters with the m16 series and the dime is placed on the wings of the front sight. Boys on that rifle it can be done, and I would bet the barrel is thick enough on the MLII, I will try it.
You just have no idea what kinds of offhand drills they put us through as shooting instructors and team members, lol, the grass week for recruits is easy in comparison. How would you like to hold the gun in an offhand postion for a 1/2 hr straight, and have to do pushups if you let it down? Yup, no joke
JJ the tem jarhead, well lets just say I don't believe your not poking fun.
