Sig MCX Virtus Patrol - proprietary upper/lower system?
Is this a proprietary upper/lower system?
I see a local LNIB for sale, with the Sig piston upper.
Just wondering if I can change the upper to any other manufacture upper?
I would like a dedicated 22LR upper, and then possibly a target/varmint .204 upper.
