M4 Mini Marshmallow Rifle

not much to say but its just an old airsoft m16 i had gathering dust and decided to turn it into a marshmellow gun. its pretty good shoots mini marshmallows though still workin on it because i need to seal the pieces. im also still workin on a way to aim this at least a little bit i might make a grenade launcher sight. and if anyone wants the measure ments for it ill post them and also only cost about 5 dollars for the pvc and i still have 5ft left over.
