Windham Weaponry has started producing the C7A1 style upper receiver… this particular model as well as all A2 style upper receivers are getting harder and harder to find. WW has a limited quantity available and they are not on the website so call to for pricing and availability directly @ 1-855-808-1888 to grab one. Word is they are available with or without all the hardware.

Glad to see the A1 upper is still alive somewhere!
