Great gun, I got it about 9 months ago to replace my G&G M16 when that broke in half. This is my 4th AEG, and my favorite so far.. it has great externals as well as internals, plus it comes with a more powerful spring. The gun itself is easy enough to take apart, I installed my old G&G's M16 barrel into this and simply covered the protruding end of it with a silencer, and it has thus increased my M4's range in outdoor combat to that of a longer and bulkier M16.
Good out of the box accuracy and firepower
Easy to disassemble
Comes with a new spring
The spring in the magazine catch is weak, and some magazines will simply fall out, this can be fixed with a piece of duct tape, but it's annoying in combat to have to deal with.
The pins holding in the front sight were HELL trying to get out, it took 2 hours of hammering and 4 bruised fingers to finally get them out.
(Besides that, it's a great gun for both outdoor and indoor combat, I suggest it to anyone looking for an M4!)
