Accessories Proof 18" CF 6mm ARC barrel modified for LMT MRP & JP BCG

I have a proof research 18" CF 6mm ARC barrel modified for an LMT MRP by D Wilson. It will come with a JP BCG and a few mags. This barrel is an absolute hammer with factory 108's. It has under 150 rounds of factory ammo through it. I am asking $850 shipped for the barrel, BCG, and mags. Zelle or Venmo. Video below of 500 yard grouping at the Clinton House in SC.
