Picked up an FS2000 the other day. Got it new from a local dealer. It came with one mag and manual. I added an ERT sling, Eotech 552 with GG&G quick detach mount and flip up lens covers. The front sight is a GG&G spring actuated flip up sight and I also have the rear flip up sight but it doesn't fold down on a flat rail. Oh well, guess it'll go on the flat top AR and I'll order front and rear folding sights from Yankee Hill for the FN. Now I need to order a Monolith tri rail for it.
