Custom laser barrel invisible

[TheRealPinkoScum]

I made a very simple mod that adds physical damage to a laser rifle. What I did was make a copy of the standard laser rifle barrel and just added the physical damage to it. However, when applied to a laser rifle, the barrel is invisible. The only thing I did was add the physical damage to the copied barrel and added the "bautomatic" line to it (because I hate the dumb spinning barrels on the vanilla auto laser rifle.) I can't figure out why it wont render. Can anyone tell me how to fix it.
