The replica is primarily composed of reinforced polymer made of nylon fibers and metal parts. The polymer used is characterized by high strength, a rough texture, and a matte finish.

The most important parts are made of metal, including: the flash hider, outer barrel, dummy slide, shell ejection valve, fire selector switch, cylinder head release button, magazine, QD stock attachments, pins, and charging handle.

The barrel is a Specna Arms proprietary design that combines aesthetic appeal with excellent ergonomics. Every component has been manufactured and assembled with meticulous attention to detail. The model features enlarged controls on both sides (selector and magazine release) and a functional bolt.

The Light Ops stock is a minimalist canteen with a reduced weight and a sleek, modern design. It features non-slip rubber cheek pads and a distinctive curved rubber flask foot that rests comfortably on the shoulder.

In addition to the aforementioned internal parts (TDC Magnus™ chamber, Æther™ gerabox shell, Helium™ flat rubber, sealed aluminum nozzle), you will find the following inside the replica:

- 8mm bearings
- steel gears
- a polycarbonate plastic piston with all-steel reeds
- a high-quality 6.03mm precision barrel
