More pipes than a rocket asks for, all in a gun that fires snowballs. The blueprint can't be learned, and the recipe sits at a Level 3 bench anyway, so a snowball gun in your box came from the winter event, not from your queue.
Enjoy it while the snow lasts. Once the event ends, the gun is a box of parts: the recycler returns one metal pipe, sometimes two, and about half the high quality metal. Not much for what went in, but more use than a dead slot. If your group is short of pipes for a raid, that trip to the recycler comes sooner.
