If you want to migrate your V2 mechbox from one gun model to another, pay attention to the following issues:
1, if you want to achieve maximum FPS performance and avoid misfeed / jamming, replace the air nozzle with a gun specific one.
2, if you want to move from, say, M4 to MP5 or G3 to M4, you will need to replace the switch plate for sure. To make the look consistent, you should also change the trigger.
3, if you want to move from a short barrel setup to a long barrel setup, be prepared to change the cylinder for optimal performance. Having an insufficient cylinder in a long barrel setup can lead to serious FPS drop. On the other hand, having an “over-capacity” cylinder on a short barrel setup can affect bullet stability and make the gun very noisy when firing.
