MK2 Picatinny
This is an attachment for the Dart Zone Pro MK2 meant to add picatinny rails to the top of the blaster. To install this attachment you will need to make some cuts in the shell of the blaster.
To install first disassemble the blaster and remove all internals.
Next take the picatinny adapter and slide it over the metal barrel. This may require you to heat the picatinny loop and hammer the barrel through said loop. While sliding the two parts together periodically set them into the blaster to check that the picatinny will end up where you want it.
When the picatinny is where you want it over the barrel mark the front and back of the picatinny on both halves of the blaster shell.
Next cut away the material between the two markings. Periodically set the barrel and picatinny in the blaster to check the depth of your cut.
After your cut is finished and the two halves fit cleanly around the picatinny you can reassemble the blaster.
