OK I have away way to long kits sitting on the shelf and no action on my part. I have been mesmerized by my Sterling SMG kits. Its going to take some time on those. Copes barrel? It appears to be a normal 16 inch barrel. I have printed the PDF spec sheets from the Library and made some comparisons. My thought was at that price you could cut it down to the 12.5 length verses the original at 80$ or more. I realize that just about anything can be done but it appears with a little TLC towards the end of the barrel you could make it work. Any thoughts
I do see the obvious difference in length to the gas block be the AMD has a shorter piston. The barrel has the Dia. some turning down right after the hand guard slot.
