The Tokyo Marui M14 is another great product from the engineers at TM. The stock spring in the M14 is stronger than previous guns coming from Marui, and will produce over 300 fps with a .2 g bb. I purchased my first M14 from first launch in America in August, 2005 and have not had any problems, even after upgrading. While many people find the gearbox to be overly complicated, after multiple upgrades I find it is one of the best designed gearboxes Marui has made to date.
The hop up on these m14s is one of the best I have seen, and these guns stock can shoot further than many upgraded guns on the field.
Pros: Great gearbox, great range, mostly metal, uses large battery.
Cons: Long, heavy
If you want a gun that can shoot further than most, this is for you. If you want a gun for CQB look at something else, like the M14 Socom. Overall I really enjoy this gun, and now own three of them, and havent had a problem. Of the 20 plus guns I own these are my favorite rifles.
