Description
Griffin Complete Uppers offer premium features and reliability to each user, and allow end users to configure their upper to fit their needs. Complete Uppers now incorporate Griffin’s tabbed rail and upper receiver interface, preventing unintended rotation of the rail. A shim is positioned between the clamp surfaces that locks into the barrel nut, preventing pull-off of the rail under extreme circumstances.
Griffin Complete Uppers can be configured with the user’s choice of barrel (416R SS or 4140 CMV Chrome-Lined), furniture color, BCG (Standard or Gas Pocket), and gas block (Fixed or Adjustable). Flip-up M2 Iron Sights are included to enhance value to the end user.
Note: The price of this upper does not include the cost of a muzzle device, but you can add one to the order using the buttons above. If you do not wish to purchase a muzzle device with the upper, please select the NONE option. Griffin Complete Uppers do not come pinned and welded.

Fully satisfied. I tested out a few different uppers when deciding to move from a carbine-length to mid-length upper. This turned out to be among the best of those uppers. This was easy to perfectly tune (landed on an H1 buffer), leverages premium parts across the board, runs very smoothly, and is functioning flawlessly. The customer service is also excellent. I highly recommend Griffin and this upper. Thanks!
