The availability of "2 Guns" in 720p resolution, with Hindi and English audio tracks, via a .mkv file extension, suggests that the movie has been ripped from a high-quality source, likely a Blu-ray or a digital distribution platform. The fact that this specific version is being shared via a keyword like "-FilmyHunk- 2.Guns.2013.720p.Hindi.Eng.mkv" implies that there is a demand for pirated copies of the movie.
