Hey guys, long time no see! I have been in Ohio for college this past school year and miss TN airsoft quite a bit. Anyways, I have had my KWA KM4 RIS 2GX for a little over two years now. I've played about once a month since then. My spring, I feel, is becoming slightly weaker than where I want it to be. So, do you guys have any suggestions on the best brand to put in my KWA for optimal performance and quality around the 400 fps mark?
Thanks!
