In looking thru my hakim stuff I have an interchangability list between the hakim/ rasheed/ljungman and it shows the reciever cover is interchangable between the hakim and the ljungman this is the cover that has the handle on it and yes the rubber(shell buffer) so the shells bounce off and also don't get dented so they can be reloaded too. In Jack First's catalog its called "Bolt Cover" #3 on the list in the green book volume 2 #12 so he will know what you are talking about. BigBill
