    KWA KM4 SR10 AEG - KWA’s first generation of AEGs got great reviews, but there were a few issues that the company needed to resolve – and resolve they did. The 2nd Generation of KWA AEGs have so many great points that it’s hard to focus in on just a few. The 2GX gearbox and 2GX bucking make these fantastic, consistent, and reliable guns. The SR10 offers the airsofter a carbine-sized weapon with a full rail-system up front. If you want to add an optic, you can do so, but the gun also comes with flip-up front and rear sights that are fully adjustable. A longer-than-average inner barrel helps with accuracy, and with FPS clocking in at around 400, you’re going to get excellent range as well. The sleek crane stock can accept butterfly, nunchuck, or crane stock batteries, and if you already have a lipo battery, the SR10 comes lipo-ready. If you are a fan of the M4 but want something a little more unique, this is the AEG for you.

    1. Great gun

      I have had this gun for a year now and i am loving it. The best part is you can hit longer range shots and it is accurate. A couple of negatives is one it is heavy so not advised for younger players, two the stock can be a little wobbly but tightening the screw will help, and lastly it scratches easy.
