Rossi Sigma, Black

The Rossi Sentinel Sigma is a compact electric M4 (AEG) with a 5.5" CNC-machined aluminium handguard and an overall length of 650–730 mm, depending on how far the stock is extended. At 2000 g it is a light rifle for CQB, indoor sites and players who move a lot during the game.

The body is reinforced polymer, while the handguard and outer barrel are metal – a split that keeps the weight down where the rifle is not under load and adds stiffness where accessories are mounted. Inside sits a version 2 gearbox with electronic trigger and active braking. The rifle shoots approx. 97 m/s with 0.20 g BBs, and the short 180 mm inner barrel makes it quick to move around corners and through doorways.

Compact M4 with electronic trigger

What you get in the Rossi Sentinel Sigma:

• Electronic trigger with active braking: The trigger is electronically controlled, and the active brake stops the motor right after the shot. That gives a crisper response in semi and less wear than a traditional mechanical contact set.
• Reinforced V2 gearbox: 18:1 steel gears, piston with steel teeth and 8 mm metal bushings. The spring guide is a quick-change type, so the spring can be changed without opening the gearbox.
• 6.02 mm precision barrel: The tight-bore 180 mm inner barrel leaves less clearance around the BB than a standard 6.08 mm barrel, giving a more consistent trajectory.
• 5.5" aluminium M-LOK handguard: The CNC-machined handguard has M-LOK slots for a light, foregrip and laser, and the rifle has polymer flip-up sights.
• Retractable stock and metal magazine: The nylon-fibre stock is adjustable for length, and the included metal hi-cap magazine holds 300 BBs.

Maintenance and safety

• Battery and charger are not included. Charge LiPo batteries with a LiPo charger in a fire-safe bag, and remove the battery from the rifle after use.
• Adjust the hop-up to your BB weight. For the hop-up and precision barrel we recommend clean, polished BBs such as Hank Tactical BIO 0.28 g.
• Clean the inner barrel with a cleaning rod if accuracy drops, and carry the rifle with the safety on and the magazine out. Our workshop in Aulum, Denmark can upgrade and service it.
• Always wear approved eye protection or a mask. You are welcome to test-fire airsoft replicas at our shop in Aulum, Denmark.
