Went out this weekend to try out the M12 (I bought it used at a gun show).
Turns out it has a malfunctioning lifter. I need to fix this.
So, no dove for me today. I'd like to go out next weekend. Anyone got a link for the M12 schematic?
Give it a deep clean, when I got mine it was very gummed up from too much oil and not being used for over 30 years.
Also take your time with the disassembly and reassembly, they are a bit different than newer type pump shotguns.
