G&g mp 5 a5

[spddmn]

Hey guys, picked up the above mentioned gun from one of the members here, and its set up for CQB indoor type games. Unfortunately, there aren't any options to do that around here. With that being said, what spring would you recommend to increase FPS, as well as should I upgrade the innerbarrel? The hop up and what not has already been upgraded...The FPS right now is sitting in the 290 to 300 range. would like to get it up a bit more however. Any help would be greatly appreciated. I am going to be working with my team Gun Doctor not only to get the upgrades done, but to also learn how to do it myself.

Generally G&G's come with good barrels (especially the Toptech series which come with tightbores). What do you want the FPS to be? For around 400, you will need an M120 spring.

Then he should be able to answer all these questions for you.

Agreed - should be able to answer these questions, but finding the time to meet with him etc is hard - figured if I asked you all, then I would have a general idea, and try and work on stuff myself, when I get stuck then I absolutely make the time to see my Gun Doc. I am kinetic anyway. Once I start doing something, I learn much faster than just watching someone else. I am more methodical that way.

Thanks for the information though, I really do appreciate it.

110s should put you near 400 maxing out around 410... a 120 spring maxes out at 420 maybe 430 depending on how good the seal is and how he cylinder/barrel are configured
