I have Bushmaster XM15-e2s hbar that was a police trade in. This is an older rifle built in Windham Maine prior to Remington moving production. This rifle is pretty original other than, sling mount receiver end plate, later mil-spec carry handle, and kns ball tip extended height front sight to work with carry handle. Mainly looking for $550 cash but might get distracted with trade for? Any questions or pictures just let me know.
