I have an M1A in a Sage EBR CQB chassis that accepts any m4/ar stock. Im looking to trade just the m4 adapter portion PLUS 150 CASH for the standard EBR collapsible stock and mount portion (not the chassis portion) along with the grip. Mine has a nice tango down grip on it.
Id also be interested in just selling the M4 CQB adapter with grip for 120 O.B.O
Heres a pic of my rifle:
