The WE-Tech M16A3 Version 3 Open Bolt Airsoft Gas Blowback Rifle brings one of the most iconic rifles in U.S. military history to the airsoft battlefield with unmatched realism and performance. Combining full metal construction, powerful recoil, and WE’s advanced open-bolt gas system, this rifle delivers an experience that blurs the line between replica and reality.

Designed for both GBB beginners and seasoned players, the M16A3 GBB is the perfect blend of authenticity, reliability, and raw shooting power. From its detailed external build to its consistent internal mechanics, WE-Tech’s craftsmanship is evident in every feature of this rifle.

Realistic Full Metal Construction

The M16A3 Open Bolt features a full metal receiver, barrel assembly, and stock tube, giving it the same solid weight and feel as the real-steel rifle. This realistic heft enhances immersion, especially during milsim events or tactical training scenarios.

Complementing the metal externals are the nylon polymer handguard, M16 fixed stock, and serrated AR-style pistol grip, all designed for comfortable handling and stability. The rifle’s detachable carry handle allows players to mount optics or run classic iron sights, depending on their loadout preference.

Every detail — from the integrated sling swivels to the functional bolt catch and forward assist — adds to the authentic AR platform experience.

Open Bolt Gas Blowback System – Power Meets Precision

At the heart of this rifle is WE-Tech’s Version 3 Open Bolt Gas Blowback System, a major step forward in GBB technology. The open-bolt design not only enhances gas efficiency but also provides a snappier recoil and smoother cycling, replicating the operation of a real firearm.

The realistic hard-kick blowback delivers a satisfying jolt with every shot, while the long 509mm inner barrel ensures superb accuracy and effective range, ideal for medium- to long-distance engagements.

With a muzzle velocity between 410–480 FPS (using Green Gas), the M16A3 provides serious on-field power and consistency. It’s also compatible with Red Gas or Propane, allowing players to fine-tune performance for different climates or engagement styles.

Reliable in All Weather Conditions

One of the standout features of WE’s latest gas system is its improved cold-weather tolerance. Unlike older GBB rifles that lose performance in lower temperatures, the M16A3 Version 3 maintains solid cycling, reliable gas output, and consistent accuracy even when magazines are cold.

This makes it a dependable rifle for year-round outdoor gameplay — whether you’re training in cool climates or taking part in winter milsim events.

Firepower and Functionality

The M16A3 offers fully automatic and semi-automatic fire modes, giving players tactical flexibility on the field. The realistic selector switch, trigger response, and bolt operation make it an ideal platform for players who want a genuine AR training experience.

The 32-round WE open-bolt magazine feeds smoothly and efficiently, while the adjustable hop-up system allows users to fine-tune their shot trajectory for pinpoint accuracy.

Threaded at 14mm CCW, the outer barrel is compatible with most standard airsoft suppressors, tracer units, or flash hiders.
