The all new KJW KC-02 V2 Gas Blowback Rifle is a bit different from your run of the mill rifle. This gun features 4 rails and comes with rail covers for three of them. You'll have plenty of rail space for any accessories you could need such as a bipod, scope, lasers or lights. This rifle does include the flip up front and rear sights and unlike most rifles of its type this gun does feature a retractable M4 style stock. This is a very fun gun and is very easy to shoulder and use. The included magazine holds 30 rounds and will have enough gas to get through all 30 with ease. You can't go wrong with this rifle.
