I was cleaning a new purchase and I took out the trigger mech to clean it. There was a lot of grease, grass seeds etc. and I dumped the gunk out of the receiver and a roll pin came out too. - About 3/4 in long and 3/16 in dia. can anyone point me to an exploded view. I'm familiar with rem 1100s but not the BPS. In the mean time I'll keep tinkering.- I suspect the top,(small) receiver pin goes thru it.
thanks
James
