WE Open Bolt Full Metal M4 T91 Carbine Gas Blowback Rifle – Realism, Power, and Performance Perfected

The WE Open Bolt Full Metal M4 T91 Carbine Airsoft Gas Blowback Rifle (Black) combines raw realism with the legendary performance WE-Tech is known for. Designed for players who demand high power, durability, and a truly authentic shooting experience, the T91 delivers intense recoil, reliable gas efficiency, and field-dominating accuracy—all in a rugged, full-metal package. Whether you’re an experienced airsofter or a newcomer exploring gas blowback rifles, the T91 stands as one of the most satisfying and realistic rifles available today.

Realistic Operation Meets Modern Performance

Powered by WE-Tech’s latest open bolt gas blowback system, the M4 T91 delivers an incredibly realistic shooting experience with every pull of the trigger. This new-generation system is not only more gas efficient but also engineered to perform in a wide range of temperatures, minimizing the effects of cold-weather cooldown that can plague lesser rifles.

The open bolt design improves realism, reduces weight, and enhances cycling speed—while maintaining excellent consistency and power. Every shot produces a crisp, hard-kicking recoil that mirrors the handling and operation of a real carbine. For those who crave authenticity and tactile feedback, the WE T91 is built to impress.

Premium Construction & Attention to Detail

True to WE-Tech’s reputation, the M4 T91 Carbine is built almost entirely from metal, ensuring long-term durability and a realistic feel. The receiver, barrel assembly, and buffer tube are made from high-quality alloy, providing strength where it counts most.

The rifle’s nylon fiber handguard, stock, and pistol grip combine lightweight resilience with comfort, making it ideal for extended matches or training sessions. The 4-position retractable stock allows players to easily adjust the rifle’s length for different play styles, from tight CQB encounters to open-field engagements.

A railed upper receiver with a detachable carry handle provides multiple mounting options for optics and accessories. Combined with adjustable front and rear sights, this setup ensures precision aiming whether you prefer a classic iron-sight setup or modern optics.

Performance That Dominates

Under the hood, the WE Open Bolt M4 T91 pushes performance to the next level. With a muzzle velocity between 410 and 460 FPS (using 0.20g BBs and Green Gas), it’s perfectly suited for outdoor fields where range and stopping power matter most.

The 363mm precision inner barrel delivers consistent accuracy, while the adjustable hop-up system lets you fine-tune trajectory and BB spin for the perfect shot every time. The rifle operates seamlessly with Green Gas, Red Gas, or Propane, offering flexibility for different climates and power needs.

For even greater versatility, CO₂ magazines are also available—offering players the option for enhanced power and consistency during cold weather operations.

Authentic Controls & Realistic Handling

From its working bolt catch to the fully functional fire selector, the T91 is designed to replicate real firearm operation. The semi and full-auto fire modes, combined with realistic magazine capacity (32 rounds), deliver a balance of authenticity and gameplay practicality.

With a total length of 817mm to 900mm (adjustable) and weighing 3100g, this rifle feels balanced and natural in the hands. Whether you’re training, skirmishing, or collecting, it captures the essence of a professional-grade tactical carbine.
