10.3-inch MK18-Style SBR on a VLTOR MUR-1A and Sharps Livewire

A slimmed-down 10.3-inch MK18-style rifle: a Daniel Defense barrel under a Centurion C4 quad rail on a VLTOR MUR-1A upper, with a Sharps Bros Livewire lower. An Aimpoint CompM5b on a Bobro mount, a Malkoff/Arisaka light, a Geissele SSP trigger, a chopped B5 CAR stock and an Otter Creek Labs Polonium K complete it.
