This gun is not very modifiable, but first take off the foolish wings. After using them once, they have probably already fallen off. Only sissies have heave wings that can't hold ammo or serve a useful purpose. Use only Magnums. The "laser" sight is adjustable, but with magnums(fat darts) it can be accurate to 15 ft. or so.
For some reason, I tied a piece of fishing wire(20 ft.) to a magnum, then the other end to the barrel of the gun, and shot it. Worked well, it would be a really cool grappling hook if the wire didn't have a 10 lb test weight.
One time I got kicked in the leg by a lego man, then I dismembered him and fed him to the neighbor's cat, who choked on it and died. When the Vet autopsied the cat and found the lego man, my neighbors asked me if I did it. I said no. Sure fooled them. Huhuhuh...
