SIG 551 Gas Blow Back Rifle



One of the best and most realistic Airsoft guns available on the market! Body jolting heavy recoil action and field strips like the real SIG 551! This GHK is manufactured very closely to the real thing, with stamped steel body, CNC aluminium hand guard & polymer furniture with folding stock.


Not only did GHK put extreme efforts into the shell of the gun, the barrel is a tight bore 6.03mm for high accuracy, steel fire control group for durability, high quality German made recoil spring and high efficiency gas magazine.


Its quite common for Gas Airsoft Guns to freeze up in colder temperatures, surprisingly the performance on these GHK guns are awesome even in temperatures around 10 degrees they don’t freeze up! The high efficiency gas system of the SIG will shoot 60 rounds on Full-Auto and 120 rounds on Semi-Auto with one full green gas magazine fill.
