I have a complete (minus stock) Colt M4 lower receiver. Was previously painted before I owned it. Comes with all lower parts except for the stock. $425
May consider trades for:
Aero Precision M4E1 ambi lower, BA Hanson 13.7 or 13.9 barrels, Aero Pro BCG, Holosun 507C-X2, Eotech XPS-2, Geissele Mk16 handguards, and maybe other items. 804-835-3470, text is best.
