Elite Tactical Performance | <20J / 16J Versions with adjustable regulator

The Milsig T17 Pro Hellcat Less Lethal Full Metal is a high-fidelity, 1-to-1 scale M4 replica designed for those who demand ultimate realism and uncompromising performance. Built on a full-metal platform, the Hellcat utilises the revolutionary Mini D.E.R.P. (Dynamic Exo Retention Platform) blow-forward system.

Equipped with the F.B.U. (Flexi Breech Unit), This marker seamlessly handles both standard .68 caliber roundballs and shaped projectiles in both semi and fully automatic modes.

Core Technologies:

Mini D.E.R.P. (Dynamic Exo Retention Platform)

The heart of the Hellcat is a self-contained power plant that houses a compact HeatCore within a single functional mechanical unit. This modular design allows the entire internal assembly to be removed and operated independently of the body.

• Consistency: Delivers superb +/- FPS stability over the chronograph.
• Efficiency: The latest generation features a softened spring and modified bolt for optimised air consumption.
• Control: Includes an integrated regulator for precise velocity adjustment.

F.B.U. (Flexi Breech Unit)

The F.B.U. is a breakthrough in breech design. Its flexible architecture automatically adapts its size and feed path to suit modern-shaped projectiles. This system is so efficient and stable that external ball detents are no longer required, significantly reducing the chance of projectile breaks.

Mechanical Full-Auto System

Experience the thrill of full-auto without the need for batteries or electronics. Our patented mechanical system features a realistic fire selector with three distinct modes: Safe, Semi, and Full-Auto.
