GHK Tactical SG551 Gas Blowback Airsoft Rifle

The GHK Tactical SG551 Gas Blowback Airsoft Rifle delivers an exceptional combination of realism, durability, and performance, setting a new benchmark for elite gas blowback rifles in the airsoft world. Whether you’re a seasoned milsim player or a collector looking for authenticity, the SG551 is built to impress with premium materials, true-to-life controls, and robust functionality.

Constructed with a steel body and reinforced with polymer furniture, this rifle is made to endure harsh field conditions while maintaining a highly realistic weight and feel. The steel gas tube and integrated steel barrel contribute to its structural integrity and operational reliability, delivering performance that closely mirrors its real-steel counterpart. A manganese phosphate surface treatment topped with a CERAKOTE coating not only enhances corrosion resistance but also gives the rifle an authentic matte finish that appeals to both functional and aesthetic demands.

What sets the SG551 apart is its versatile fire control system, which includes semi-automatic, three-round burst, and full-auto modes—a rare and appreciated feature in gas blowback rifles. This level of control allows players to adapt their shooting style on the fly, whether laying down suppressive fire or conserving ammo with precise shots. A folding buttstock adds further versatility by reducing the rifle’s overall length, making it ideal for both close-quarters combat and ease of storage or transport.

The aluminum Picatinny M1913 handguard allows for easy mounting of accessories such as lights, lasers, or vertical grips, giving you the flexibility to customize your loadout. Flip-up front and rear iron sights provide solid backup sighting options and align perfectly with modern optics if you choose to upgrade. The authentic handguards and pistol grip are dimensionally accurate, providing excellent ergonomics and reinforcing the rifle’s true-to-life appeal.

Internally, the SG551 is engineered with a 340mm+ inner barrel, contributing to impressive accuracy, especially when paired with the adjustable hop-up system. The realistic 32-round gas blowback magazine, compatible with GHK SG553 magazines, enhances the realism while maintaining feeding reliability. The gun is powered by green gas, producing consistent FPS between 370-395, making it a formidable option for outdoor gameplay and tactical training environments.

One of the standout features of the SG551 is its realistic field-stripping capability, which closely replicates the disassembly process of the real firearm. This makes it an excellent training platform for users seeking a non-lethal system that offers the handling characteristics of the actual SG551. With a total weight of approximately 3550 grams with magazine, the SG551 provides a solid and realistic presence in-hand, preferred by enthusiasts who demand an authentic airsoft experience.
