The whole AR series of weapons, but in particular the M4 carbine, is an incredibly well known weapon the world over as a symbol of American military technology. In Airsoft they are so well established that everyone has one, so prolific most would argue its over used but the upside to that trade off is the ease of repair and maintenance with the variety and options of aftermarket spare parts, modification and upgrade parts. Equally so, in the newly revitalized gas blow back rifle market, many top brands have submitted their contenders and now KSC offers theirs.
Full metal, full weight, full size and fully operational and realistic full bolt carrier group. This weapon is clearly aiming at the top of the pile as another high end gas blow back rifle replica with sufficient realism to simulate real steel use in a theatrical / handling training right down to close scrutiny. Setting it apart from other brands somewhat, KSC has put their now well established System 7 technology (in this case the newer variant System 7 two) to use in this gas rifle system so that it too can enjoy the benefits of clean feeding and operation with modern materials and improved design over older technologies.
Handling standard Top / Green gas out of the box, this M4 clocks in at a good 340 fps nicely hitting the 335-365fps sweet spot for transitory close-to-mid range style enjoyments so typical with indoor room / corridor and confined space trench / corner / trees type of CQB situations. At that power its high enough to reach out and touch human size targets at long enough range to cast threat out to typical Airsoft middle range expectations yet still week enough to not inflict too much harm or discomfort on lightly / unprotected skin at ranges less than a few meters.
Although fairly standard with higher end models, an immediately noticed factor of this M4 when picking it up is how solid it is. Everything sits together so securely that it almost feels like one solid piece of weapon which when combined with its high metal content makes it really feel as robust as a weapon of this type should be. For the time being, the magazine is proprietary as such only KSC gas M4 magazines will fit this model of M4 and no other.
