I bought a DMR style stock off of a buddy recently (I'm not sure of the brand) and I have an echo 1 M14 Socom that i am trying to put it on. The problem I'm running into is the receiver doesn't want to seat into the DMR stock. Its like the motor is getting stuck on something in the stock that won't let it go in all the way. Has anyone ever installed one of these stocks? Am i missing something?
