CYMA Full Size M16A3 Airsoft AEG Rifle w/ Lipo Ready Metal Gearbox & Full Stock

Command the field with the CYMA Full Size M16A3 AEG, a purpose‑built platform that brings dependable performance and upgrade potential to skirmishers, entry‑level competitors, and training teams alike. Combining familiar M16 styling with a robust metal gearbox and modern battery compatibility, this rifle is an ideal primary weapon for players who want a dependable out‑of‑the‑box experience and a clear upgrade path for future tuning.

Purposeful Construction — Lightweight, Tough, Reliable

CYMA crafted the M16A3 with a lightweight injection‑molded polymer receiver that keeps the overall weight manageable while remaining highly durable in field conditions. The polymer components provide impact resistance and lower fatigue during long matches — while the core drivetrain is a full‑metal Version 2 gearbox, designed for longevity and straightforward upgrades. If you want to step into custom tuning or repairs, the gearbox is fully serviceable and compatible with a wide range of aftermarket parts.

LiPo Ready Gearbox — Power & Upgradeability

The M16A3 arrives LiPo ready, offering compatibility with high‑output battery packs for snappier trigger response and reliable cyclic rates. The full‑metal gearbox accepts standard Version 2 upgrades (gears, pistons, springs, and more), making this rifle a perfect base for players who plan to tune for higher FPS, better trigger feel, or more consistent performance. Whether you keep it stock for field reliability or upgrade for competition, the platform supports both paths easily.

Practical Ergonomics & Optics Ready Design

This model features a detachable carry handle mounted on a flat top receiver, giving you the classic M16 silhouette plus the flexibility to switch to modern optics. The full‑length top rail ensures quick and secure mounting of red dots, scopes, or iron sights. The polymer A2 style handguard preserves authentic looks while giving a comfortable gripping surface for controlled aiming and recoil management.

Performance‑Focused Barrel & Feeding System

Equipped with a 405mm inner barrel, the M16A3 delivers enhanced accuracy and range compared to shorter CQB barrels. The included 300‑round hi‑cap magazine provides sustained fire for suppression and objective play, and the rifle accepts any Marui‑compatible M4/M16 series mid‑cap, drum, or hi‑cap magazines for versatile loadout options.

Battery & Field Convenience

A fixed M16 style stock houses a large battery compartment ideal for standard 9.6v small butterfly batteries or other compatible packs (battery not included). The wiring and compartment layout prioritize user‑friendly access, making battery swaps and maintenance fast between games.

Tuned for the Field — Versatile Firing Modes

With selectable semi‑automatic, full‑automatic, and safe modes, the CYMA M16A3 adapts to multiple playstyles — from precise single shots to controlled full‑auto suppressive bursts. The adjustable hop‑up lets you dial in consistent trajectories for different BB weights and environmental conditions, helping you squeeze every meter of performance from the 405mm barrel.

Package & Support

The rifle ships complete with the AEG, user manual, and a 300‑round hi‑cap magazine so you can get on the field immediately. Backed by CYMA’s reputation for practical, reliable airsoft platforms, the M16A3 benefits from broad aftermarket support and a global community of tuners and techs.
