Hey whats up guys! I was curious about some upgrading with a gun I plan on purchasing! Now what I was wondering: what are some simple upgrades that I can do to a brand new gun that doesn't involve doing any wire cutting or anything in that category! Things that I'm talking about are things such as a simple barrel change or Spring change. Now if you guys would be so nice, that you could list some companies and parts I could look for to make the gun last longer, or run better! Thanks a ton! TriadAirsoft Edit: Oh and my gun will be a SOCOM GEAR M4, which has VFC internals . Also, I play CQB so keep that in mind!
