Hey guys!!! So im a big CQB player and im running a tiny CQC M4 made by Elite Force. The gun cronos on average around 300 fps, with .2g So far the gun is internally stock and on the outside just some basic attachments were added. I have a vertical grip, Version 2 peq box and a red dot. Now here is where i need help. My field requires the gun to shoot under 350 fps. I wanna get the best out of my gun with out buying a new one or spending a ton of money! If any one knows or can suggest what i can do please let me know (internal and externally!) Here is my gun thus far http://imgur.com/a/IkEZp actual gun link http://www.evike.com/products/51224/ Thank You!
