Ok to start off with I have the Cyma M14. Now what I am wondering is should I upgrade the M14 or should I get the JG M-4 S-system? If I do the M14 I will most likely get a 6.03 barrel, new hop-up, new long type motor, rail mount, and shim it. If I get the JG it will most likely be the externals first as I've heard JG internals are fairly awesome. What I'm really asking is what would you do? The cost of the gun wouldn't be a problem and I would have about 200 for upgrades. And to make sure you know, I play field.
