I have a New Colt SBR M4 lower sitting at my dealer has not had tranfer completed, my plans changed was planning on a MK18 build but decided on a different SBR so this one is up for grabs, rare find as Colt lowers are hard to get let alone a factory SBR asking $775 shipped to your FFL SOT where legal , the lower is complete with no stock, mocked it up with my mk18 upper and stock but those items are not for sale or included
