Lancer Tactical Gen 4 Valiant M4 AEG Airsoft Rifle w/ Aster ETU

Built for Performance. Designed with Passion.

The Lancer Tactical Gen 4 Valiant M4 AEG is more than just another rifle—it's the result of a direct collaboration between Lancer Tactical and the well-known airsoft creator "Valiant Airsoft." Purpose-built for both competitive players and serious enthusiasts, this rifle brings together rugged externals, refined internals, and advanced electronics for a field-ready platform that performs right out of the box.

Advanced Internals with ASTER ETU Precision

At the heart of the Gen 4 Valiant lies the GATE ASTER programmable ETU, giving you fine-tuned trigger control, burst settings, and advanced safety features. Upgraded 16:1 steel gears, a metal tooth piston, and a 25K high-torque motor ensure fast cycling and reliable power, while the quick-change spring system makes FPS adjustments effortless. This rifle also features a CNC rotary hop-up and 6.03mm tightbore barrel, delivering impressive accuracy shot after shot.

Striking Aesthetics with Battle-Ready Ergonomics

The full metal receiver is engraved with the “Valiant Airsoft” logo and pairs with a custom M-LOK handguard that’s suppressor-ready and mission-focused. Its ergonomic polymer grip and redesigned delta stock offer excellent comfort, while the flat trigger enhances trigger response. Flip-up Flaxion sights, a one-piece outer barrel, and modern styling complete this all-around performer.
