Built pretty much the same gun but with a Gemtech Blackside silencer and the original stock (soon to be a Magpul CTR). I put a 6.04x455mm Systema semi-tightbore in it. It was a comprimise because of the places I have to shoot bios. The only other mod is a TM EG1000 motor when a motor lead connector broke inside of its shrink tubing and arced so much it fried the battery and got the motor so hot I dropped it. Added a UTG fore-hand grip with sealed battery compartment. BEWARE of 2008 KWAs for one reason. The trigger switch retention posts shear off. It is a known fact at the factory & service department and will be reinforced in their 2009 line. Mine snapped after about 10,000 rounds. A local airsmith/guru fixed it by insering a high grade screw and dremeling off the threads. Now it's stronger than it was originally. Other than that, the KWA M4 is THE BEST gearbox to build a gun around. 8 & 9mm bearings, gears that barely need shimming because the tolerances are so accurate, strong pistons and heads that give great... compression ;-) With a 110 spring I was getting 380 with .25s. That's before the longer barrel. If it wasn't winter time and battery drain wasn't an issue I'd drop in the Mad Bull 130 spring I have for it. The gearbox will easily handle it, the motor will pull it but the 9.6v 1600 mah Intellect butterfly won't last long pulling it in 0 degree C temps. Time to go lipo and end those worries... Only I have over $200 in batteries and a BOL DATA charger that does me no good with LiPos =o( The only bad thing I have to say about KWA guns is that their trades are ugly. But I'd rather have a gun that's built solid, runs great and has boring trades than a gun with a real steel trade and crappy performance.
