You really are a noob.
What you've got there is a broomstick with a few protrusions.
It uses real textures instead of Blockland ones, you don't group your primitives, and for that matter, you only use primitives instead of extruding. If you tried doing it correctly and basing it off a real weapon, you might just get something that looks somewhat similar to a gun, And by the way, "Old Betsy" is a horse's name.
