TRINITY ARMAMENT Alpha Carbine HPA 11.5" with PULSAR D2 & TITAN II Bluetooth (GATE x Arcturus)

TRINITY ARMAMENT Alpha Carbine HPA 11.5" 

Forget piecing together custom builds, the future of high-performance HPA Airsoft Rifles has arrived factory-assembled. Born from a unique partnership between Arcturus Tactical and GATE Enterprise.

The Trinity Armament Alpha Carbine is the world’s first factory-built HPA rifle. It comes pre-installed with over £400 worth of GATE internals. Combining rock-solid metal externals with dual-solenoid precision, this is the ultimate out-of-the-box primary. This Airsoft Rifle is for operators who demand instant trigger response, extreme rate of fire, and seamless app customisation.

Factory-Installed GATE PULSAR D2 Dual-Solenoid Engine

At the core of the Alpha Carbine Airsoft Rifle sits the revolutionary GATE PULSAR D2 HPA engine. Using a closed-bolt system and an innovative BB feed system, the PULSAR D delivers precise, repeatable shot placement. It stays accurate, even during high-speed automatic bursts. The dual-solenoid setup unlocks insane performance scalability:

• Tuneable Velocity: Adjust output seamlessly from 250 to 650 FPS (depending on regulator pressure and field limits).
• Extreme Rate of Fire: Fine-tune cycle speeds anywhere from 1 to 40 rounds per second.

TITAN II Bluetooth ETU & Smart Realism

GATE’s flagship TITAN II Bluetooth® Electronic Trigger Unit controls the engine. It pairs with an adjustable GATE Nova Trigger. Connect wirelessly to the GATE Control Station (GCS) app on your smartphone or smartwatch to calibrate trigger sensitivity. You can also configure binary or burst modes, monitor battery telemetry, and automate engine synchronization.

To elevate tactical immersion, the Alpha Carbine incorporates integrated GATE Magazine and Bolt Catch sensors:

• Real-Cap Functionality: The system blocks firing when the magazine is removed.
• Working Bolt Catch: Requires physical activation of the bolt catch lever after reloading an empty mag. This gives you realistic gas-blowback manuals of arms with total HPA consistency.

Arcturus Full-Metal Modular Externals

The platform is wrapped in heavy-duty full-metal CNC-machined receivers and an 11.5-inch aluminium M-LOK handguard. This strikes an ideal balance between mid-range carbine versatility and tight CQB handling. Downrange precision comes from an Arcturus RS™ reinforced polymer rotary hop-up unit. In the rear, the AR MOD1 stock has an easy-to-reach battery compartment that powers the internal TITAN board.

Technical Specifications
