MacDev Drone 2 Review
It comes in a nice soft case, with Allen keys, grease, a few o-rings, and a full color manual. The manual could use a little more detail but is sufficient . The gun comes in a great assortment of colors, Black, Red, Blue, Olive, Grey, and Lime.
The marker has a nice shot and there is not much kick. I found the stock barrel  will give you a consistent grouping of paint.  At 280fps the gun has very good efficiency. I was able to play 15 minute scenario games, using a hopper and 3 to 4 pods and still have 1500 psi remaining after starting with a 3000 psi fill. The gun only weighs 1 pound 14 ounces.
The one down side of this marker that I found was the positioning of the trigger frame. It was difficult to use the front grip, like I would on a Planet Eclipse Geo or Ego. The trigger frame is close to the handle and restricts your hands positioning. However, once you get used to it, it becomes comfortable with the built in rubber handle.
Maintenance and break down of the gun is very easy. If you remove the grip frame, you will find there are no wires you need to worry about pulling out because of the connection board. The bolt system is easily removed and because there are only a few moving parts it is easy to clean and relube after a day of paintball. The manual does walk you through everything you need to do to maintain the gun, trouble shoot any issues and adjust things like the trigger or board settings.
There are already a few upgrades for the gun. The first  good upgrade is the MacDev Drone 2 Gold bolt. It is reasonably priced at $50. It helps prevent ball roll back and improves shot consistency. It also helps you shoot more fragile paint and prevent  the ball from rolling back.  They have now released an OLED board for this marker, however it is priced at $200. I think that is a little expensive for a marker that is costing you $500 but if you want that option, you can always add it.
Overall, I highly recommend the MacDev Drone 2. It has a very good price, and instead of picking up an older used marker you would be able to pick up a brand new marker that performs very well. I would recommend picking up a Drone 2 Gold Bolt. It is definitely worth the money.
Overall Gun rating 8/10
