Carter Reed (verified owner) –
Kit is well made and fits together quite easily after the required modification to the gearbox. If you are not comfortable cutting the gearbox apart I do not recommend buying this kit.
A quick note, you should locktite the screw that holds the nozzle adapter on, mine backed out after about 5 games.
Unfortunately it would seem because the screw backed out of my nozzle adapter the f2 broke the pins off the side pieces that hold it in place.
So make sure that if you experience any missfeeding or jams to stop immediately or else you risk breaking those tabs, they are only 3d printed after all and not indestructible.
Overall very happy with the product and the final result of having an insanely snappy and fun aa12.
