Velocity Arms V4 S-System ?
 

I'm a bit lost with gearboxes. Is a version 2 any good ? Does anyone know if this gun is a good buy?

Please use the search function as both your questions have been discussed allot.

The V2 gearbox is one of the more popular ones so you will have a fair bit of aftermarket support. They are however not the most robust and are known to have catastrophic failures, mostly in colder weather. The V3 box is almost the same, but has a few enhanced features that will elongate the life of the box.

The VA series guns have gained quite a good reputation from people on this forum when it comes to cansoft guns. From my understanding they are using JG guns for their custom lines.

thanks! And have since realised that I should have researched/ or should have posted it in the noob tank before.
