Excellent product and a guy who stands behind what he builds. I think he designed his first can in his mid teens and actually started building them a couple years later. I have another Shadow XL TI .30 that I am waiting on right now. They are great.
I have a SRT VAPR and it is an awesome can light, quiet, and repeatable accuracy every time you put it on or take it off only reason I like my thunder beast a bit better was it was cheaper to buy at the time
