Geissele URGI 10.3 inch mk18 exact clone upper ($1300 new) spikes lower, cmmg lower parts kit, pistol brace ($475)  Doesn't include comp m4, but that could be negotiated.   Camo spray paint is perfect for Missouri but can be stripped.  Only trade would be a Bren or different high end AR with 11.5" barrel or longer.  I can add cash
