Okay, so I looked at a lot of the slings you can get, and wanted a sling that puts the rifle in the muzzle down, vertical, front and center position, but I didnt have any capital to spend on such things (poor college student getting ready to ship to basic soon)...THEN:
My MSII instructor was giving us random advice about LDAC (he was a TAC last year and returns this year). One of the things he told us to do was dummy cord our rifles with 550 cord. I dont think its what he had in mind, but this is what I came up with combining the concept:
make a short dummy cord, total length about 12-14" long, requiring about a 25-30" length of cord, by tieing the ends together in a parallel knot
using the attatchment point on the shoulder of either the LBE or LBV (if LBV you must use a part that is sewn down on both sides, not the snap down part), thread the clean (unknotted) end of your cord UP through the point (whether it be metal ring or nylon slot).
thread that end DOWN through the loop until it comes all the way up and down. You now have a big loop hanging off your shoulder.
pull it nice and taught by the very end with one hand, grasp the middle with the other. let go of the end and allow the lower half to seperate back into a keyhole/loop shape. reach through the loop with the free hand and grab the taught upper half.
pull what you have reached through the loop to grab back where you reached from. this makes a loop that sinches tight the further down you pull it. push it all the way up to make it as big as possible. insert buttstock of rifle, sinch the loop tight against the stock where it is closest to the reciever and has the smallest diameter.
I will attemp to take demo pics of this if I can get a rubber ducky for a few minutes, or maybe next week at LAB if we do a STX.
This produces a very cost effective, very secure, comfortable single point sling that keeps your weapon ready to go, and pointed in a safe direction. I wouldnt recommend it for hands free use, but it will certainly keep you from losing you weapon, and keep out of trouble with people who are constantly looking to get on to you for your muzzle being pointed wrong or your weapon not being at a ready position.
