KWA KM4S-TACTICAL [2nd Generation] 2010 version. KWA's latest products include high quality LiPo-ready Airsoft Electric Guns (AEG), and great gas pistols. KWA features professionally crafted and manufactured airsoft at an affordable price.

The KM4S-Tactical sports a skeletal fore grip made with impact resistance polymer and alloy rails. The skeletal fore grip can accommodate a variety of batteries including an 8.4V 7-cell NiMh mini battery pack. Full metal, adjustable flip-up front and rear sights are used to maintain the streamline look of the gun. Like the KM4A1, the KM4S-Tactical is equipped with a reinforced, high performance metal gearbox and is LiPo-ready when you are. Performance specs match those of the KM4A1.

Note this gun does not come with a battery and charger

Great gun with only 1 flaw May 6, 2009
Reviewer: Ilya Monastyrsky from Portland, OR United States  
This gun has worked wonderfully for me, the only problem I have with it is the BUIS are flush with the rail, and end up being too low to cowitness with any optics that you may put on your rifle like an EoTech or an Aimpoint.

This is only a very minimal complaint so it still gets 5 stars in my boook
