Weird glitch?

was playing a game of Domination just then. Put the flame thrower on the Famas but ended up changing guns to the enfield or what ever it is, the glow from the flame was still there on the barrel after i changed... looked cool but not right aha



(was taken on my phone)

Had that happen when playing splitscreen with my brother. He picked up my gun (which had the flamethrower attachment), used it, then when he spawned next with his gun it had the flame there.
