The Hi-Capa 4.3 is very an extremely capable and accurate pistol that makes it one of the most popular in Airsoft. It is hands-down the most reliable gas blowback pistol of all time - and there is good reason for that! It's no wonder that so many custom guns are based on the Hi Capa platform and most competition shooters will not shoot anything else. Metal parts included : recoil spring guide rod, nickel plated hammer, adjustable rear sight, front sight, magazine catch, magazine, and frame with an ABS grip. The barrel is also handsomely nickel plated. Good for 280fps when using Green Gas, but many upgrades are available for this pistol that you can reach higher power with some modifications! Gun is well balanced and hefty thanks to the metal frame. Extremely smooth slide cycling action with strong recoil and a pleasant assortment of clicks and clacks when the slide is pulled back makes this gun a lot of fun to shoot. There is an under rail for accessories like flashlights and lasers!
