Good video. I wouldn't mind building a piston SBR at some point. Not sold on the whole piston idea, but it's interesting enough to try on a build one of these days.

I'm running an Osprey kit on one of my mid-length rifles. Love it! I'm now just under 1k rounds in and have never had an issue of any kind.
