The KM4 CQB airsoft rifle was designed and engineered especially for airsoft close quarters battle scenarios where a 350 FPS limit is imposed. Straight out of the box, the KM4 CQB shoots consistently at below 340 FPS but fires more than 20+ rounds per second using .20 gram BBs. The KM4 CQB is "LiPo-Ready" and shares all the standard features found on the KM4A1 plus several new enhancements like the new heat sink motor plate to dissipate heat build up generated by the high speed performance motor. All of the internal components have been finely tuned and re-calibrated to provide maximum rate of fire but maintaining the 350 FPS limit.. 

This AEG comes with a hicap.
