The Dye Rotor R-2 built on the incredibly popular original Rotor and made it even better! One of the biggest changes that the R2 made is the ability to expand the top shell allowing it to have a larger capacity, going from 200 rounds to 260 rounds. They also made the motor tension / speed adjustable, so you can turn the tension down, so it is softer on paint, but a little bit slower, or have it apply more tension to and make them as fast as possible. Other new features of the R2 is that it will beep at you indicating when you will need to reload soon and when you need to reload and it has a quick release rain lid, allowing you to quickly switch to a speed feed.
