For: Tokyo Marui MC 51 AEG Airsoft GunI actually got one of these in a trade recently, and I have to say it is pretty darn good!! The main reason I wanted this particular gun is because I am sick of all the M4's everywhere and wanted to know which gun is mine! I personally don't like that weird retractable stock that comes on them, so I have a G3 full stock and a custom 6 pos M4 stock (gotta make it mine somehow). Also, like other Tokyo's, this thing needs to be upgraded with at least an M120 to compete against Classic Army's and other pre-upgraded guns. I have installed 6mm bearing bushings (it comes with plastic, and mine came with some kind of non-bearing metal), a new Systema piston and gears, and a G&P M120 motor with M120 spring. The gun overall is very reliable and doesn't need any upgrades for those doing CQB. I guess you could go by the following breakdown:
-Very reliable (like all TM AEG's)
-GREAT for CQB
-TERRIBLE retractable stock
-Hard to mount a silencer (hard to find a G3 adapter)
-EG700 motor (definitely has to be replaced w/ any upgrade...TRUST ME)
Overall, I have to say that I am pleased with this gun. I've had Classic Army, ICS, and those other high-end guns, but they all have their PRO's and CON's. If you want a different gun than what everyone else has, BUY THIS. The ratio between these and M4's where I play is about 1:10.
