Видео с вентиляционными отверстиями в трубке газоотвода.

Sorry for the video quality, working alone again. Muzzle blast shook camera and I couldn’t see it until I got it on a big screen. Major changes were made to the cantilever scope mount and the Vortex Crossfire I was using broke (I assume from recoil). I switched to a Millett TRS1 and scope movement was halved and groups tightened up immensely. Video was shot with the Casio EX-F1.
