Once Jeremiah fixed the selector (which technically didn't effect the performance), so far it shoots fine. The cooldown is horrible but when the mag is warm, it shoots pretty hot (~400 with .25's) and the blowback is nice and crisp. The blowback is quite a bit harder than on most smaller gas guns (IE Maruzen MP5k, KSC TMP, KWA Mac11). I haven't had the chance to compare it to a WE or KJW yet.
