Flex. Flex, Flex, Flex. How do I put this.....
You've just started (YAY!), you're enthusiastic (DOUBLE YAY!) and you have aspirations of greatness (HUZZAH!). BUT - you have just started. Setting your sights high is one thing. Saying already that you simply must have a training weapon is pretty much the equivalent of a guy driving around on P plates asking everyone about the service intervals on a Lamborghini. By the time you've been playing long enough for your CM16 to be the limiting factor in your games you will almost certainly have realised that actually a better G&G or indeed the Marui Recoil range is more than good enough for what you want. Nothing wrong with aiming high, nothing at all. Just maybe get a bit more play under your belt first to prevent going off half cocked...
