Crafted from a solid block of aircraft-grade aluminum, this hopup chamber delivers unmatched accuracy, consistency, and durability. Its tight tolerances ensure flawless performance, shot after shot.

Featuring a precision rotary dial, this hopup chamber allows for fine-tuned adjustments, giving you complete control over your BB trajectory. The re-engineered hopup levers and nubs are optimized for R-hop, Flat-Hop, and Standard-Hop systems, ensuring straight and accurate shots every time.

Designed to accept nozzle lengths from 21.00mm, this hopup chamber is fully compatible with most aftermarket soft and hard rubber buckings, maintaining optimal FPS without dropping BBs.
