The GU1200S AIR RIFLE 4.5MM presents a notable evolution in air rifle technology, featuring a gas-spring mechanism and an under-barrel cocking lever. This design sets it apart from traditional fractures, offering unique advantages for shooting enthusiasts. One key benefit is the stationary barrel during reloading, ensuring minimal deviation between the barrel axis and aiming line, especially when paired with optics. This translates to enhanced precision and reduced errors in every shot.

Constructed with a high-quality steel barrel, the GU1200S incorporates a gas spring, a departure from traditional twisted wire springs. This choice significantly reduces vibration during firing, contributing to improved accuracy and consistency. The rifle boasts an automatic safety fuse, promoting safe handling and use.

The sighting system includes a sight bar and front sight with fiber optic threads, facilitating precise aiming even in varying lighting conditions. The stock and bed are crafted from durable polymer, providing a balance of strength and weight. The 4.5mm lead bullets utilized as charges make it suitable for both recreational shooting and more formal sports applications.

While slightly heavier and longer than its “breaking” predecessor, the GR1200S, the GU1200S AIR RIFLE 4.5MM offers a novel shooting experience, making it an excellent choice for those seeking reliability, accuracy, and versatility in their air rifle. Whether engaged in target practice or competitive shooting, the GU1200S delivers consistent performance and a satisfying shooting experience.
