Performance and operation

The rifle operates on Green Gas and boasts a muzzle velocity of 260 to 300 FPS with 0.20g BBs, corresponding to an approximate energy of 0.63 to 0.84 J , compliant with European recreational standards. The shell-type magazine holds 30 rounds, and each pump cycle fires three BBs to simulate a flat, penetrating shot. The selector switch allows switching between 3 and 6 rounds, providing control over the firing pattern depending on the scenario.

Ergonomics and modularity

The partially metal body and one-piece Picatinny rail ensure rigidity and optical compatibility. The 6-position M4-style stock improves adjustability based on body size and game type (CQB or open field). M-Lok slots, an A2 grip, and an included angled grip allow for quick customization. QD sling attachment points and adaptive mounts complete the package.

Safety and maintenance

Comply with local regulations (sale to adults, use in designated areas). Drain the gas system before long-term storage and regularly clean the barrel and hop-up to maintain accuracy and lifespan.

FAQ

Q: What is the power in joules of this replica?
A: With 0.20g BBs and 260-300 FPS, the energy is approximately 0.63 to 0.84 J, a perfect power for use on all terrains.

Q: What type of gas should I use?
A: Use high-quality Green Gas specifically designed for airsoft replicas. Avoid gases not recommended by the manufacturer to prevent wear. Use a lower-power gas such as Nuprol 1.0 in summer and a higher-power gas such as Nuprol 3.0 when temperatures are below 10°C. This will allow you to maintain optimal power and range in all seasons.

Q: Is the charger removable and compatible?
A: Yes, it's a cartridge system, not a magazine. These removable 30-round shotgun shells are designed for this model. This makes the replica more realistic while allowing you to carry compact spare cartridges.

Q: Can a scope or red dot sight be mounted?
A: Yes, the one-piece upper Picatinny rail allows for the installation of reflex optics and viewfinders.

Q: What interviews are necessary?
A: Clean the barrel, check the hop-up, lightly lubricate moving parts, and drain/check the gas system after prolonged use. Remember to drain the gas from your replica between weekends of play, and above all, do not leave the replica in the sun during periods of high heat.
