He was definitely using a closer-range bolt action in a few places. You can tell by the smaller scope magnification and no scope sway. For example the clip at 2:50.
Pretty easy to see when the TSAR was used, since the lower zoom optics wont turn your screen outside of the scope black while ADS. Besides the last part of the clip the TSAR was also used at the sunderer-hugging scene.
Wow you land some amazing shots. I hope Im not on the same server as you. Jumpjetting is safe! Till now at last... What I have to say as well is that I like how the video(s) are made. Showing nice stuff, excluding downtimes, etc. really nice!
