www.replicaairguns.com Type: Airsoft Gas Rifle. Manufacturer: KJWorks. Model: MK1 Carbine. Materials: Metal and plastic. Weight: 2.71 pounds (1.23 kg). Total Length: 33 inches (83.8cm). Barrel Length: 17 inches (43.2cm). Barrel: Metal non-rifled. Propulsion: Green Gas. Action: Semi auto double action only trigger. Hop-up: Adjustable metal Hop-up. Ammunition Type: 6mm plastic Airsoft BB's. Ammunition Capacity: 17 round full size drop out metal magazine. FPS: 450+. The KJWorks MK1 Carbine Green Gas Airsoft Rifle is really just a modified MK1 Pistol by adding a longer barrel and rear shoulder stock to the pistol grip. I guess it is a good use of an already popular pistol design to give us a light weight and somewhat compact Airsoft sniper rifle for Airsoft games as it does have a fairly high velocity claim. Because of the high 450+ fps I would not recommend it to anyone playing in close quarters as it could injure other players so keep that in mind. If you are looking for a lower cost and fairly compact Sniper Rifle for some outdoor shooting, then it might be just the right pick for that. I am hoping my upcoming Field Test Shooting Video showcases it nicely so keep checking back for that Review Video down the road a bit.
