This brand new Mossberg 590A1 arrived ($729) so I did a total disassembly, cleaning and lubrication. I got all the below listed parts installed, forend sharkskin stipple job is completed, and the barrel is at Vang Comp getting modification with ports. I'll post updated pics when I get the barrel back from Vang Comp. The 6-position stock and forend are listed for sale in the classifieds if you are interested.
