Sidenote of some of the OPD I got from my IP on the topic of M4's in the aircraft.
He has a rig using nothing more than a D-ring and an elastic pistol retainer cord that attached to his belt loop and was D-ringed to the hand grip on the M4. The reason was that a crew in his unit went down hard enough to wreck the aircraft but not hard enough to sustain injury and had to immediately abandon the A/C due to landing in close proximity to bad guys. Well in the fog and haze of having just being put through that crash both of them completely walked away from the Aircraft without their M4's. Basically this little jerry rig kit started being used by some people as a helpful reminder of "Hey dude this is your brain I know we're a little shaken but your gonna want that thing thats tugging on your waist." And since its attached to something as easy to rip as a belt loop if for some reason you gotta jump out of the A/C in a hurry its not going to hang you up any worse than your helmet cables or HDU.
The "Clips" on the Kiowa are strictly for holding the M4 onto the dash in case somebody flies outside that wussy 60 degree bank limit. Doors off smors off, Skids are for Kids.
