I agree with lag. I think you should retoole the second half of the animation. When operating a bullpup rifle (from what I understand) it is actually pretty difficult to insert the magazine that way. What they do (I think) is press the butt of the rifle against their breast and rotate it on the X axis so that the magwell is facing them, and insert the mag that way. I think you could create a much more interesting animation that way. Also, the gun has a bolt catch, so you should operate that instead of the bolt. I have no idea where it is though, ask ross. >.>
Also you should render your animations with about 10 blank frames on the end (just resting at origin) so that youtube doesn't do its gay little cut off thing.
