KWA is well known for making some of the highest quality, most durable, most dependable airsoft guns in the industry. The KM4 SR7 is certainly no exception. This AEG is practically flawless, right out of the box. The external build quality is excellent. The parts are rock solid and there is very little wobble to speak of. The body is full metal and has a beautiful matte black finish with KWA trademarks on the lower receiver. The RIS is solid yet lightweight and allows the addition of any accessories that might be desired, such as foregrips, lasers, and flashlights. The crane stock is adjustable to 6 positions and clicks into place nicely when adjusted. The stock contains the battery, and for this AEG a we recommend a nunchuck style battery with mini connector, though some stick type LiPO batteries will also work. Internally the gun is built like a tank. KWA Airsoft products are "Engineered to Outperform" and this is definitely exemplified in the 2GX gearbox found inside this AEG. The gearbox features 9mm ball bearings and is heavily reinforced for maximum durability. The operation is very smooth able to put out a higher rate of fire than a standard gearbox. Coupled with a KWA ultra high-torque motor the performance is phenomenal. The gun is LiPO ready without any modifications. If you're looking for a high end AEG that will perform right out of the box the SR7 DEVGRU by KWA is an excellent choice.
