I have just sent my M1A back to springfield for repair, the Oprod was disengaging and leaving the bolt hanging in the receiver. Anyone else had this problem? When the oprod was locked back on an empty magazine, the oprod could easily be jiggled loose from its track. I will post Springfields response as soon as I hear back from them.... Anyone else experience this problem?.. You with the hair?.. How about you with the gun grease on your hands?
