Someone has a Windham made Bushmaster XM15 for sale here on the forum. The old Bushmasters were pretty close to what you are looking for. I have an older one carry handle model w/ 14.5 pinned and welded Izzy brake that was purchased on Dept letterhead many years ago. Good luck!Sell me your old, neglected M4 classic style builds. Carry handle or SOCOM styled rear peep sight a plus. KAC quad rail (or clone) a plus-plus. PM what you got.
