    Great lightweight upper. Ran flawlessly. Can’t beat it. It really should cost more.

  2. kevinrainey1 (verified owner)

    Fit and finish are fantastic. The upper went on a form 1 spikes lower, and will be running a sandman S can. The length feels great, so happy I went with the 12.5. Thanks!!!

  3. Coby A. (verified owner)

    Haven’t shot it yet but appears to be very good quality.

  4. Josh Arem (verified owner)

    so far its a great upper fit and finish is perfect. finish matches my spikes lower and a PSA lower. they have pretty quick shipping as well.

    Awesome product! Totally amazing value. Perfect for an at pistol build. Only issue I’ve had so far is the dust cover button is broken and takes some toying with to get it to close.
