Softair Zone shows us the various features of the S&T UST9 Sportline AEG they have at their store. The UST9 is a lightweight and comfortable replica of a widely-used German submachine gun, is powered by an advanced G3 gearbox, enabling a firing rate of approximately 24 BBs per second. Its solid ambidextrous construction, made of durable plastic, features Picatinny rails on the upper receiver and handguard for attaching optical sights and other tactical accessories. The well-contoured pistol grip enhances shooting accuracy, while the easy-to-reload mid-cap magazine holds 100 BBs. The side-folding stock facilitates transport, reducing the replica’s length to less than 45cm when folded. Ideal for intense close-quarters combat, the ST G3 gearbox ensures reliable performance. The modern mosfet enhances trigger control, reduces reaction delays, and saves battery energy. The quick spring change system allows power adjustment to suit different game scenarios without disassembling the entire gearbox.
