I have been a gunsmith for nearly forty years. I worked at Griffin and Howe in the late 70s, was a NYC licensed gunsmith (repaired firearms for all all enforcement agencies in the area) in the 80s and 90s, did warranty work for Colt and S&W, and most recently was the head gunsmith for Empire Rifles until their closing.
I am not stating any of this to impress you, but simply to state my background and perspective. I recently purchased a B.E.A.R. Elite upper kit from you. It has been a long time since I was so impressed with both the design and execution of that design in a firearm.
