Grey Ghost Upper Receiver for the M11/9 SMG

Introducing the production version of the Grey Ghost Upper Receiver for the M11/9 SMG designed by Mike McManus. This upper receiver is the perfect host for the Vegas SMG 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.  There is currently a wait list for this upper and as of the time of this post, we are shipping the first 10 out to customers.  If you would like to be added to the wait list, please contact us at:

Here are some pictures of customer customizations:

This one has a round and more compact charging handle and a customer supplied 3-lug double threaded barrel:


This one has a 3″ piece of picatinny rail welded onto the ejection port side of the upper receiver to accommodate additional accessories.  (The tape is on the end of the barrel to protect the threads during shipping because the customer did not want the flash hider as he will be shooting suppressed):

These two pictures below show the Uzi Style Folding Stock tucking under the fore grip extension.  If you watch the video below you will see toward the end of the video the folding stock with the stock arm welded to the other side of the butt plate to accommodate long uppers. 
Last but not least, here is a video showing the production upper as well as assembly instructions:

If you have any questions or comments, please be sure to let us know!

Happy shooting…
