    Great paperweight! Got it into an even more useful item with minimal effort, the jig does a great job on this lower.
    Not yet assembled but everything looks up to spec.

  2. Walton S. (verified owner)

    The product is great. The finish was near perfect. It milled out well. I was a little concerned with some of the small bracing around the trigger and FCG but it was much stronger than I expected. Great job!!

  3. Brandon T. (verified owner)

    Fast shipping, excellent product thank you.

  4. Anonymous (verified owner)

    The fit and finish between the upper and lower are outstanding! Barrel fits snugly with no wobble. Need to complete the lower next when I get the time.
