As I mentioned awhile back, when shooting my AR with an MOE stock, the thing rattles the hell out of my collarbone. It is then sore for three or four days afterward. After comparing mine to a few other people's collar bones, mine sticks out more than most. I didn't have a problem with a sopmod stock that I used to own b/c of the shape of the butt of the stock (it runs in a straight line from top to bottom). Problem is, I like my MOE and don't want to change. I am trying to figure out how to build up the bottom part of the stock to bring it in line with the top, so that it is recoiling into the middle part of my pectoral instead of the collar bone. I was thinking along the lines of applying something like silicone from the middle to the bottom of the stock in order to achieve what I am looking for. Can any of you industrious types give me any ideas? And before anyone suggests bench presses, I've been doing that regularly for about twenty years now. Thanks
