    New to the collection just waiting on my silencer to get approved.

    Sig 556xi Russian
    Battlecomp BABC
    Magpul Pro BUIS
    Tromix Charging handle moved to the left hand side
    Krebs Enhanced safety
    Shooting Sight 556xi Trigger kit Hammer and Sear for a smoother pull
    German "Matt" Sorco Trigger spring kit to reduce the pull weight of the trigger
    DDLE Folding Stock adapter
    Strike Industries 7 position stock tube
    BCM Gunfighter Stock and additional Hardware
    BCM Front grip short
    Aimpoint T1 (not mounted)

    My only gripes are the rail and new side folder... I didnt really pay attention when they said 1913 aluminum rail but from what I have read thru the forum is that I need to buy the rail sections. Why couldnt Sig give me at least 1 rail section? And the side folder people said they have used this side folder with a Magpul UBR stock so I figured it would work with a stock similar in width and work fine, but I found out otherwise it wont sit flush to the upper/receiver.

    I am still looking at a way to fix the stock issue to make it flush and hoping my paperwork gets approved for my new can.
    I hope these upgrades will inform other 556xi owners on what after market parts will work.

    Where did you get that rail? Is the bottom rail a separate piece from the stock upper rail?

    the 1913 rail you need to call Sig Customer Service to order it and you must have the factory metal rail.. the plastic MLOK versions use mlok 1913 rail sections.
    yes the rail as far as I know either you choose a plastic mlok rail or a modified 1913 metal rail fore end. the rail slides off as a bottom piece but the upper 1913 section stays in place unless you remove the screws that hold it down, torx screws if im not mistaken.
