Diamond Dogs Mastiff – Compact 180FPS Carbine AEB

Product Note: Only for Sale Mid-November 2026

Compact, aggressive, and built for close-quarters gameplay, the Diamond Dogs Mastiff AEB combines a distinctive Vector-inspired tactical appearance with a versatile select-fire system. Featuring a magazine-in-grip design, an extendable buttstock, and a performance-focused drivetrain, the Mastiff packs serious functionality into a compact platform.

The Mastiff offers two distinct operating modes. Switch to full-auto for a firing rate of up to 5 darts per second, or disengage the selector and use the manual-prime, single-shot mode for muzzle velocities of up to 180 FPS. At the heart of the Mastiff is a professional-grade drivetrain built around the Sweetheart Storm 32:1 gearbox, a 550 high-torque motor, and a metal CNC catch. These components form the foundation of a platform designed for dependable operation and satisfying performance.

Designed with close-quarters handling in mind, the Mastiff measures just 42cm in its minimum-length configuration and weighs approximately 1.4kg. Its extendable buttstock allows you to adjust the length of pull to your preference, while the integrated 12-axis BCAR comes standard to help improve dart stability and achieve tighter groupings. With its mag-in-grip feeding arrangement and distinctive Vector-esque styling, the Mastiff offers a compact alternative for hobbyists seeking a feature-packed AEB.

Note: When the blaster is not in use, switch it off and pull the trigger once to release the spring and fire. Darts sold separately.
