Jesse James started off the new year with a bang -- because he posted video on his resurrected Twitter page of his new favorite toy ... a sniper rifle!
JJ -- who got the gun from his girlfriend Kat Von D -- posted the video last night and said, "Wanna know why @thekatvond is the Perfect Woman? She Got me a SNIPER RIFLE for Xmas!"
BTW -- Jesse's not the only one in puppy love -- Cinnabun has a new boyfriend named "Pierre."
Let's hear it for the happy couples.
