  • Product Description

    The A&K S-System is a highly popular M4 variant with a unique rail system for attaching a wide assortment of accessories. The S-Sytem's RIS is a hinged, clamshell design that serves dual functions- securely holds a 8.4v brick-style battery and offers picatinny/weaver rail space on the top, bottom, and sides for the attachment of accessories such as the included foregrip, or lights, lasers, launchers, and more. The S-Sytem's RIS rails on the handguard are also detachable for added comfort when holding the handguard when not using attachments. Other features on this rifle are the metal flip up front and rear iron sights, multi-position LE style polymer stock, and included foregrip. Overall, the S-Sytem is among the most popular rifles for first-time airsoft players and continues to prove a go-to gun for years to come.

    1. Good rifle

      This gun is just awesome. Almost 100% metal. Fps is about 320-340 fps with .2 grams so it goes far and hits hard. Just make sure you use .2 grams and higher ONLY. I made the mistake of using .12s and my gun jammed and broke :( but that was my own fault. Definitely best gun i've had. on Jul 27th 2016

    2. Great rifle

      This gun is great, with few problems. It truly is full metal, and for some, hard to handle. It shoots at about 335, on a good day. However, it has a terrible battery compartment that is hard to master. I'd recommend getting the Jg S-systems if you want to get an s-system. But I do in fact recommend this gun for cqb skirmishes and assault. on Jul 26th 2016

    3. Overall good gun

      This gun overall rates a b in my book. Love the fact that most everything about this gun is metal besides hand grip, stock, and hop up. First ill start with the positives to this gun. Decent rate of fire not the best but definitely good if u get into a fire fight and need to get a nice spray of bbs out to hit them. The fps is not quite accurate on mine it started at 325 and settled at 310 all aeg settle a little lower after being used a little. Accuracy is pin point if u know how to square in your sights on the gun. Another cool fact is the large amount r.I.s. mounts it gives u. Me personally I use a scope for mainly recon. So its nice to have the built in POP up sights because I can easily just take off the scope and rock on. The high cap mag is a nice addition. Now for some cons on the gun obviously fps is a little low of what is shown but not to much. My gun came with a hop up that did not work I had to open it up and re align the gears not to difficult but sad that I already had to fix it. Battery compartment is a little difficult to master but once u get the hang of it. It will be no problem for u in the future. For the shipping part I had no problems. I got my gun in four business days from the order date. box was a little banged up from the shipping but all parts advertised were there. So like I said my fellow airsofters its a good beginner gun and hope u enjoy this one and hoped my review was helpful. on Dec 23rd 2014
