I came across a couple FN M240b Barrel Assembly with nice and shiny bore/rifling. I am not too sure of the market price for them so if I am price gouging it is unintentional. If any wisdom on valuation or in general would help myself and interested parties please feel free to Pm me or reply. Price for Barrel Assembly with Heat Shield As it sits is $400. I also have 4 m249 saw heat shields that are new for $90 shipped. If interested PM me. Thanks for looking.
