some people acutally cut electric tape to just the right size, and wrap ONE layer (so no overlap) on the inside of their barrels, making it kinda like a better fitting barel, or really ghetto detents (off of M.CarterBrown )
wrapping your barrel will only make it heavier and louder , the holes in the barrel are there to silence it , whoever told you to wrap your barrel is a retard.
and if you cover the holes on your barrel you will have to re-crono your gun because the CO2/COMPRESSED AIR isnt escapeing through the holes therfor making your gun shoot higher
