Archived [ARCHIVED THREAD] - Osprey piston kit compatibility
Posted: 6/9/2015 12:39:08 AM EDT
I have a colt 6720 lightweight pencil barrel. I am interested in the osprey piston system and I am wondering if it will work with my .625 FSB.... Not sure if the port hole is in the same place as on a "F" marked FSB.

Thanks
