Its polymer body offers enhanced durability while keeping the weight manageable at 4.5 pounds, making it easier to handle during prolonged use. With a powerful FPS range of 380-399, this airsoft gun delivers a strong performance that can satisfy both intermediate and advanced players. The inclusion of a full metal Version 2 gearbox with an M120 spring and steel teeth piston ensures reliable and consistent firing, further supported by an 18:1 gear set and high-speed motor for precision and efficiency.

The 6.03mm tight bore barrel enhances accuracy, which is crucial for hitting targets with consistency. Users will appreciate the 9.6V nunchuck battery and charger included in the package, eliminating the need for separate purchases. The magazine options of 130 rounds or 300 rounds offer flexibility depending on the player's preference. On the downside, the blue polymer color might not appeal to everyone, and the need for a speed loader (not included) might be a bit inconvenient.

The retractable crane stock and enlarged trigger guard add to its versatility and ease of use. The 20mm optic rail provides ample space for customization with scopes, sights, and magnifiers.

The FPS ranges between 380 and 399, offering a strong shooting power suitable for most airsoft fields. Its 9.6V nunchuck battery is included with a smart charger that stops charging automatically, making maintenance easy.

One downside is the lack of a speed loader for the magazine, which could make loading 300-round mags a bit time-consuming.

The included battery and charger add convenience, making it easy to get started right away. The flip-up sights are a helpful feature for aiming accurately, although some users may want to invest in additional optics for better precision. The plastic construction may not be as robust as fully metal models, which could affect longevity during heavy use. Additionally, while the rate of fire is decent, some players may find it lower than premium models designed for more intense action.
