hey guys, seems like im the only one that got this gun in so i guess ill do a mini review for u guys!
Impression:
I ordered this gun from NitroAirsoft March 22, and i recieved it on April 2...so it took about a week and a half. Upon opening the box the contents were a bit shuffled up and misplaced. however the gun was in perfect condition.


Appearance
the gun looks amazing. at first the reciever looked metallic but a few knocks on it assured me it was plastic. the color is like my other boyi m4/203 although the m4 CASV looks a bit better in quality. although i do prefer the grey of my echo 1 m4, im not complaining.
Putting the battery in the CASV is a Pain!!!!!!theres a PEQ box which you can use if it does get too hard to fit a 8.4v in the CASV
The CASV is all metal, which of coarse makes it a bit heavier and the paint chips way too easily.



metal parts: outerbarrel, flashhider, CASV, front rear sight, sling mount,magazine, dust cover, trigger, stock tube, mag release button, hi cap magazine, fire selector, charging handle, delta ring
accesories are so-so, a crappy looking peq box, a 3pt sling, (which i dont know how to use) and a foregrip
the mag is also metal and so far feeds ok, not much to say on that

pulling back the charging handle reveals the metal hop up inside. hop up is pretty good and adjusting the trajectory of the bb is very easy (sensitive).

the muzzle can be screwed off for CQB purposes but you'd need a new inner barrel for that

the front sight is a standard armalite site but the rear is a flip up sight, that of a S-system, which are both metal
Performance:
Having just recieved this i wasnt able to skirmish with it yet but so far things are looking good. hop up is good and sensitive (the crappy bbs supplied didnt respond well but i used so .2 g crosman ones and now its pretty accurate)
FPS is pretty strong, as it goes through a coke can easily, from point blank.
entry

exit

so far im happy with it, ill probably post more when i skirmish with it this week end. i added the BOYi crane stock and mag clamped two magazines with it to make it a little *cooler*...\


oh yea Bad parts of the gun....
the fuse connector thing on the negative wire is SUPER loose, electrical tape hardlyholds it together. i suspect its just mine though. after tightly securing a battery in the CASV, it wont fire, id have to reconnect everyting again...and its so hard to secure a battery there. id bang on the foregrip a couple times to make it connect again...then it would fire...
UPDATE: (copy from a later post)Ive eliminated my connector problem...seems the negative wire is ok with the tape around it..i found out that putting upward pressure on the barrel caused a connection problem with the fuse. although it looked fine to the eye, the fuse was slightly pointing upwards. Putting the battery in the CASV put minor pressure and the barrel and thus wouldnt fire...
the solution was simple enough. i just moved the zip tie to the very front (neared to the muzzle) and it keeps it aligned now. crappy wiring i guess....
the fire selector is very loose, im afraid it will fall off with constant use, i can click it to safe and if i push upwards a little more, i could go over the boundary(which i didnt do but might accidentally)
the reciever pin isnt the kind you could push out, you need the allen key provided to tighten and loosen it out, although i havent opened it up yet.

its got tape around it but its still pretty loose
pic with the LE stock

PEQ box pictures. i cant figure out how to take out the cap thing on it. looking through a hole i can see metal plates and what looks like screws holding the cap on. i didnt want to break it so i quit trying



u can see the plates in the inside

UPDATE: skirmish report
the metal hop up envelopes the air nozzle, i snapped it off by accident, i replaced it with a jg air nozzle and tappet plate, so far so good
ROF: decent, though nothing like a TM, a new battery would be nice to replace the so-so battery (update: intellect makes it acceptable for skirmishing)
POWER&ACCURACY: quite good,hurts to get hit, good range. 100+ ft, although i cant measure quite good, but the place we skirmish at is windy, so i never fire from very far (338fps average)
BODY: this is my major disappointment, with one tab broken (weak tabs), i can see the metal of the gear box from side view(on one side), im afraid one day it will snap in half (update: zip tie fixed)
the vertical foregrip broke on me, crappy fore grip
the fire selector is so loose and last night it fell out while performing maintenence, i stuck it back on and its pretty tight now but im still worried it will fall off during a skirmish
the lower casv will come apart if you pull the fore grip to yourself with enough force, it happened alot in the middle of skirmishing (fixed with ziptie, gotta love that ziptie)
overall, it is quite a good gun, but the body problems make it hard to recommend unless your into tinkering and adjusting or if you got another body, selector switch, or foregrip laying around then you could just replace them
nice internals, tho bushings are plastic. i didnt pay attention to the spring guide but i hear theres metal at the base.
CHRONO: used my friends chrono last week, 338-344fps range. not too bad...
