Hi guys, first off - GREAT REVIEW!
I was searching on the net which is the best p90 at the moment and haven't found so far such great resource.
One little addition to the thread - CYMA now makes P90 which is branded as CM.060 , it's very cheap and I found it for 120$ at some EU distributor. I bought one 2 weeks ago, and made very few tests. The included NiMH battery was crap , and lasted only for 2 mags, but I used 7.4V Lipo which was good. Rate of fire is not big , but fine compared to my ICS M4.
I have 4 mags from CYMA and all of them miss-feed from time to time. It's rare but it happens. Stock speed with 0.20 is 120m/sec , but mine was downgraded at webshop for free upon shipping. I wanted this gun for CBQ since my other gun is tuned 129m/sec for outdoors.
Gun comes with 1 upper rail and 2 side mini-rails - 1inch long. It comes in 3 versions, with Flashhider, With Silencer and With extended Barrel - which is just an extension and not 1 piece. It also has metal upper receiver.
So far I did not opened the internals since I am very new to airsoft and no expert on gears. Only tested it outside for about 300-400 rounds, and I really liked it. Since I never had other brands P90 , I can not compare - but definetly will play with it next game at our field - to test it in action. If it's not quality enough I will buy some KA as sugested since I really liked the feel of this weapon.
