Introducing the Grey Ghost Upper Receiver for the M11/9 Full Auto SMG. This design, by Mike McManus, is the perfect host for the slow fire CF-W Bolt or stock bolt. It is completely made of steel with full length Picatinny Rail on top, an Ace Style grip out front, a flash hider with barrel threaded to 1/2 x 28 TPI, “shark fin” non-reciprocating charging handle, and built in gas deflector.
Currently there is a waitlist for this upper receiver. To be added to the waitlist, please contact us at: firstname.lastname@example.org and we will add you to the list.
