dhoistOne Thousand Ships built upper SMOS receiver and handguard in sig dark grey BA 18” mid length SPR Barrel cut by dwilson for flush fit Turquoise design honed gas block Criterion BCG FCD LDFA Geiselle ACH Very low SN OCL polonium full size direct thread mounted The upper has 150 rounds on it currently and the polonium is right around the 1k mark but shows very little wear. Will not come with optic, light or railscales unless negotiated This upper was built around the full size polonium and is a dream to shoot, I do not want to get rid of this upper but some more important purchases have come up and I’m forced to sell. I can give the full spec sheet from OTS and plenty more information if needed.
