Fusil d'assaut - Rossi - Sentinel - Beta - 9\" - 6mm BBs
Reference: 10277
The Rossi Sentinel Beta in the 9" version is a compact, well-balanced 6 mm BBs replica, fitted with a V2 QD gearbox with an 18:1 ratio and a steel piston. Its polymer body and handguard give it lightness and manoeuvrability, while its ETU and QD system make maintenance and use easier.
The Rossi Sentinel Beta with a 9-inch barrel stands out for a design built to combine compactness and reliability. This 6 mm BBs replica relies on a reinforced Version 2 gearbox with Quick Detach system, giving simplified spring access for faster maintenance and easier adjustment to suit different needs.
The internal mechanics rely on an 18:1 gear ratio, giving smooth, consistent operation, backed by a 14.5-tooth steel piston that strengthens durability. A Version 1 ETU delivers reliable electronic firing control, while the preset mechanical trigger guarantees an immediate response as soon as it's pulled.
8 mm bearing bushings help the gearbox stay stable and long-lasting, cutting down internal friction. The whole unit sits inside a ROSSI polymer body paired with a polymer handguard, keeping the weight down while ensuring good durability in use.
