BTW, those 4 filler screws in the reciever are plastic, I didn't have a problem with em, but some have reported them hard to remove, they found the easiest way is just remove the bolt and run em all the way thru so they drop into the bolt way for retrieval, it's easier than trying to back them out. /ubbthreads/images/graemlins/grinning-smiley-003.gif
