Finally releasing this after many requests. Please don't complain that it's for the 552. The 552 and the AK are the two shortest rifle reload animations, anything else looks like it's in slow motion because MW2's animations are generally really short.
Also, PLEASE don't bombard me with PMs asking for the MW2 M4, take a second and actually LOOK around, you will find it somewhere (hint: top video).
SOUNDS ARE MUCH BETTER IN GAME!
