Begadi PRO MIMAS 90 HopUp Chamber for P90

The Begadi PRO MIMAS 90 is a high-performance CNC HopUp chamber tailored for P90/PD9 series airsoft guns, delivering enhanced accuracy, shot consistency, and optimized barrel alignment. Featuring a TDC/Rotary system, it allows for smooth and precise HopUp adjustments, ensuring an ideal BB flight trajectory.

This chamber includes two tensioners—5mm for standard inner barrels and 7mm for barrels with larger hop windows. Additionally, it comes with two hardness options for rubber inserts (black - soft, red - firm) to fine-tune pressure on the HopUp bucking based on BB weight and player preference.

An added benefit is the CNC Tight Fit Nozzle with an O-ring (20.50mm), ensuring optimal air seal and energy efficiency. The CNC-machined aluminum adjustment wheel features fine-tuned 10-step markings, allowing for quick and easy HopUp settings even with different BB weights.

Constructed from 7075 aircraft-grade aluminum, this unit is built for durability and precision, with ±0.10mm tolerance, and critical components machined to ±0.05mm tolerance for superior performance.
