I hope this is not a repeat thread.I just received a tapco magazine 5/20 for my SKS.It was used by a friend before he gave it to me and it plenty dirty.I would like to a clean it but when I look online it only has the disassembly method for the regular mags. Mine has a plastic bottom that blocks me from accessing the ``tab`` to take disassemble.Any hints or tips guys¨? Cheers
