My laser pointer 
class 3a
made in thailand.
I'm not much of a gun guy, but I'm almost certain that is NOT a .50 calibre round.
without having something near it for reference, it's hard to tell, but to qualify as a .50 cal all it has to be is .5 in diameter at the base of the actuall bullet, not the casing.
I know that since I bought a dummy round once, and im using both the sticker and keyboard for reference, given that the sticker is an average laser warning label.
That's true, perhaps use key shown in he pcture, judging by the space next to it, its a left arrow key, which is approximately .5 inches, and going on the width of that bulle, it is in fact a .50 caliber. However, the casing seems to be a bit short. It could've been chopped off as not being needed.
