New Barrel,maybe a new bolt
None that I have found
This gun is very co2 conservative.It's standard barrel is accurate and this gun is not very loud. I am using Draxxus paint, and it is working well. The gun comes with o-rings and other accesories. Very nice design. Manual could be better. Allows regulators so you can use compressed air or co2. I have had no chops after about 500 balls.
If you already have a nice gun, get this for a backup, if not get this gun right now!
