    For the buffer less lowers 😎
    I SOLD this almost new Sig MCX 11,5” upper in 5.56 1/7 twist complete and ready to fire !
    Got it on a trade, this upper works with any mil-spec AR 15 lowers !
    Coolest thing about this set up , you don’t need a buffer tube , spring or buffer !
    And it is piston operated
    Asking $1,200 shipped SOLD

    I have this almost new Sig MCX 10,5” upper in 5.56 1/7 twist complete and ready to fire !

    are you sure it is 10.5? I thought they only made 11.5" ?
     
    Few pics showing upper mounted on a lower
