Combined Capacity
- Modfather alone: 0.09 litres
- Modfather + Extension: 0.13 litres
That increase in volume delivers smoother airflow and noticeably improved sound reduction, particularly in noise-sensitive environments.
Engineered Acoustic Control
The extension tube houses a single high-density acoustic foam cylinder, using the same studio-grade material found in recording studios and radio stations.
With a density of 24kg per cubic metre, the foam is designed to absorb and diffuse sound energy efficiently. It is user-washable when lead particulate build-up requires maintenance, ensuring long-term, consistent performance.
Integrated Modular Design
The Modfather Extension Tube is supplied as a complete, ready-to-configure module, including:
-
Tube connector
- Anodised endoskeleton
- Inner Cage
- Studio-grade acoustic foam insert
It can be:
- Added to a Modfather to extend the system
- Mounted at the barrel end or muzzle end
- Used independently as a compact moderator(Requires caps from Modfather)
The system adapts to your rifle, your environment, and your priorities.
Design & Finish
The extension tube features a clean, purposeful exterior, precision-machined for strength, alignment, and visual harmony with the Modfather range.
Finished exclusively in our unique darkness black, it delivers a restrained, engineered aesthetic that complements any Modfather configuration while keeping the focus on performance and craftsmanship.
