i got one of these last week,tried it at the range the other day,and it seems like it is short stroking, i called dpms about the problem the rep said to soak the bcg in clp and shoot it, i thought that wasnt correct so i called today and asked a different rep and he said the same thing, anyone else have this problem with their dpms, the problems are after it shoots it wont load the next round out of the mag,and sometimes it will stovepipe
