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+. Overall the KJWorks MK1 Carbine Green Gas Airsoft Rifle performed well, the velocity was right on the mark and was fairly consistent dropping off a bit as the Rifle cooled down from the gas. Accuracy was very good side to side but up and down I did notice more variation. The trigger is a double action only trigger so it is a bit longer and heavier than a real steel Ruger MK1 that is known for its beautiful short and light Single Action Trigger. Still the KJWorks MK1 Carbine Green Gas Airsoft Rifle performed well and I think with some good quality Airsoft BB’s, perhaps even a bit heavier than I used in this test, one could improve the accuracy at range and really be able to use this for some longer range outdoor Airsoft games. As it is a fairly light and short Rifle it would make for a super easy to pack around sniper rifle option.
