Got a spare bluetooth headset? This mod shows you how to install it into an airsoft handgun for those extra-annoying calls.
The method in this madness is so brilliant that you even pull the trigger to answer and (ahem) end calls. Even better, you listen to the barrel, and talk to the grip. Wouldn’t recommend you try this out in public though. Getting tackled by a SWAT team is hazardous to your iPhone.
