About Rossi Sentinel 10.5" Gamma
The Rossi Sentinel 10.5" Gamma is an airsoft M4 AEG with a 10.5" M-LOK handguard, polymer receiver and retractable stock. With an overall length of 740–820 mm and a weight of 2425 g, it is a light, easy-handling Carbine that works in both woodland and CQB, and an obvious first gun for new players.
Rossi built the Sentinel series with a polymer body to keep weight and price down, while the gearbox uses standard parts that are easy to service and upgrade: a V2 gearbox with 18:1 gears, a steel piston with 14.5 teeth, 8 mm bushings and a quick-change spring guide. It shoots approx. 100 m/s with 0.20 g BBs, runs on an 11.1 V LiPo with a mini Tamiya connector and comes with a 300-round polymer hi-cap magazine.
Light M4 with a standard V2 gearbox
The features that matter most:
- V2 gearbox: V2 is the most widespread gearbox type for M4s, so spare parts and upgrades are easy to find, and every airsoft tech knows the layout.
- Quick-change spring: The spring can be swapped without opening the gearbox, making it quick to adjust velocity to different site limits.
- M-LOK handguard: The 10.5" handguard has M-LOK slots for grips, a light and other accessories. M-LOK keeps the handguard slim and light compared with a full Picatinny handguard.
- Polymer receiver: A polymer receiver and stock make the gun lighter than a metal M4, and it does not turn ice-cold to hold in winter.
- 14 mm CCW thread: The barrel has a standard 14 mm CCW thread, so most airsoft mock suppressors, tracer units and flash hiders fit directly.
Maintenance and safety
- Charge the LiPo battery with a balance charger and never leave it unattended. The battery sits in the stock – remove it when the gun is stored.
- Use clean Seamless BBs such as Hank Tactical BIO 0.25 g, and clean the inner barrel if accuracy drops.
- Do not fit a stronger spring than your site rules allow – we can chrono the gun for you if needed.
- Always wear approved eye protection. Our workshop in Aulum, Denmark can fit upgrades, and you can test-fire airsoft guns in our shop.
