Hello all i just inherited 2 guns from my grandfather and i need some assistance with them. One is a mossberg model 385Kb bolt action 20 guage, the other is a Jc higgins model 103.18 single shot 22 lr. Im wondering about how to disassemble them for cleaning. The Mossbergs bolt is very very sticky and it is a chore to even rack it. Im thinking a good clean and lube would fix alot of it. Problem is this is the very first bolt action shotgun i have come acrossed and i have no clue to how to do disassemble it. Also my first single shot .22 so disassembly instructions would be helpful there aswell. Also the C-lect choke on the 20 guage wont even budge between settings. any andvice for that? Ill add a few pics for yall in just a bit thanks.
