Rossi L119 A2 Style Neptune SAS 10.5" Aeg Black

The Rossi Neptune SAS is an exceptional value offering - a full-metal CQB AEG with authentic styling, advanced ETU electronics, and robust performance out of the box. Whether you're seeking a UK-legal primary with battleground functionality or a modular platform for upgrades (optics, suppressors, stock options), this AEG is built to perform and upgrade.

Heritage & Design

• Inspired by the UKSF's L119A2 (successor to the Colt Canada C8SFW), the Neptune SAS aims to replicate real-world military styling, complete with "Neptune Spear" trident logo and unique serial marking

• Full-metal receiver, one-piece outer barrel, and CNC-keyed 10.5″ handguard deliver both strength and a precision feel

Internals & Electronics

• High-grade 8 mm bearing bushings in a reinforced gearbox using combined 16:1 CNC-cut gears, a steel-tooth piston (POM-head), and QD metal spring guide ensure reliable performance and durability

• Comes equipped with Rossi's V2 programmable ETU: features active brake, MOSFET protection, and selectable fire modes including semi-auto, full-auto, binary trigger, and burst options from 2 to 5 rounds

• Precision 6.02 mm × 300 mm inner barrel, paired with Maple Leaf 60° bucking and Omega nub, to support 330 fps output with 0.20 g BBs

Ergonomics & Handling

• Compact and agile: weighs ~2.5 kg, with collapsed length at 740 mm extending to 810 mm - ideal for CQB and short-range tasks

• Fitted with metal folding front and rear sights, a metal stock tube, and collapsible nylon-fibre crane stock for lightweight yet functional customization

• Includes two polymer mid-cap magazines (120 rounds each), UK-legal for field play

Field-Ready Features & Upgrades

• The full-metal chassis with CNC-machined handguard provides excellent rigidity - comparable with premium brands

• QD spring guide allows swift FPS adjustment; programmable ETU supports advanced trigger setups (e.g., binary, multi-burst) - a serious advantage on the field or when upgrading

• Built-in MOSFET ensures electrical reliability as batteries and performance are upgraded.
