Yep. They do ship to the US.
Whichever handle you get for your custom gun, make sure it's a handle that fits over the tube (female) rathen than inside the tube (male). I have used the Beuchat handle they sell with great success. Its resin is glass-reinforced and the stainless mechanism can hold 2x20 and 3x16 bands and still give a smooth shot.
