Gas Blowback Airsoft Rifle – Level 1 (GHK Platform)

Built for players who demand authentic handling, premium materials, and uncompromising realism, the RA-TECH Custom Daniel Defense Licensed Mk18 MOD.1 GBBR (Level 1) is a high-performance gas blowback airsoft rifle engineered to replicate the look, feel, and operation of the real-world Mk18 platform. Developed by RA-TECH and manufactured by GHK, this rifle delivers elite construction quality paired with smooth, reliable gas blowback performance.

Forged Receiver with Official Daniel Defense Licensing

At the core of this rifle is a 7075-T6 forged aluminum receiver, precision-machined by RA-TECH for superior durability and structural integrity. Forged construction offers significantly greater strength compared to cast receivers, making this rifle ideal for demanding milsim environments and long-term use. The receiver is finished with authentic, stamped Daniel Defense trademarks, giving the rifle a true-to-life military appearance that collectors and serious players will immediately appreciate.

The flat-top receiver design allows effortless mounting of optics, magnifiers, and iron sights, ensuring compatibility with modern tactical setups.

CNC RIS II Rail & One-Piece Barrel Assembly

Up front, the Mk18 MOD.1 features a CNC-machined EMG Daniel Defense licensed RIS II aluminum handguard, complete with laser-etched Daniel Defense markings. This rugged rail system provides full 20mm Picatinny compatibility, allowing users to mount lights, lasers, vertical grips, and PEQ units with confidence.

A one-piece metal barrel assembly enhances rigidity and alignment, contributing to consistent accuracy and durability during high-tempo gameplay.

Enhanced Gas Blowback Performance

The heart of this rifle’s performance lies in its CNC-machined bolt carrier group, which utilizes a negative pressure blowback system. Manufactured using advanced CNC processes and heat-treated for increased hardness, the bolt carrier delivers:
