Here's what Doug A. had to say after using this tool: " This product should be standard issue to every GI. Anyone who owns an AR and does not own this product either hasn't heard about it or is a complete moron. After using it I would gladly pay double or triple to have one. It's that F ing good! I am posting photos and my thoughts on Facebook and will post the same on Calguns. Great job!" Thanks for the feedback Doug.
