3 Legged Thing

The ModFather Airgun Moderator - Chevron

Regular price £13999 GBP

High-volume suppression. Studio-grade acoustics. Unapologetically beautiful.

The Modfather is a compact, high-capacity air rifle moderator that combines serious acoustic engineering with full cosmetic customisation and a modular expansion system designed for shooters who want absolute control over sound, airflow, and appearance.

At just 12cm / 4.7" long, with a substantial 45mm / 1.77" diameter, The Modfather packs an impressive 92ml / 3.2 fl oz internal capacity into a short, balanced body. It’s engineered to be exceptionally quiet — and built to look like nothing else on the firing line.

Then we gave it options. Lots of them.

Description

STOCK EXPECTED APRIL 2026

Studio-Grade Acoustic Control

Inside The Modfather is high-density acoustic foam of the same type used in recording studios and radio stations, with a density of 24kg per cubic metre.

This material is specifically chosen to absorb and diffuse sound energy efficiently, helping to reduce sharp muzzle crack and smooth the overall report. When lead particulate build-up eventually occurs, the foam is user-washable, restoring performance without replacing components.

Quiet isn’t accidental here. It’s engineered.


Fully Cosmetically Enhanced

This isn’t a moderator that disappears — it belongs on the rifle.

The Modfather features:

  • Three interchangeable exoskeleton designs
  • Four inner tube colour options
  • Anodised endoskeleton for a premium, engineered finish

Performance stays identical across all cosmetic configurations. The choice is purely visual — match your rifle, your optic, or your personal taste.

It’s functional art. On the muzzle.

One system. Three distinct expressions.

Every Modfather shares the same internal engineering, acoustic performance, and modular capability. The difference lies in how it presents itself at the muzzle. Each exoskeleton is precision-machined to the same tolerances, offering identical strength and airflow characteristics, with a clearly defined visual identity.

Choose the style that suits your rifle, your aesthetic, or your mood.

Slotted
Clean, linear precision with a restrained, technical look.

Chevron
Bold, angular geometry with a modern, dynamic feel.

Spiderweb
Intricate lattice design with a striking, unmistakable presence.


Cap & Thread Options

To ensure optimal performance across calibres and platforms, The Modfather offers multiple cap configurations:

Front Caps

  • .177 / .22
  • .25 / .30

Rear Caps

  • 1/2" UNF
  • M14x1.25
  • M14x1 LH (CCW) for airsoft platforms

Modular by Design

The Modfather isn’t a fixed system — it’s a configurable platform.

Optional Extension Tube

An optional extension tube adds a third chamber, increasing internal volume and improving airflow management for even greater sound suppression.

It can be configured in three ways:

  • Mounted at the barrel end
  • Mounted at the muzzle end
  • Used independently as a compact stubby moderator

Stackable System

Have more than one Modfather?
Use the extension ring to stack moderators, increasing volume and suppression further for ultra-quiet setups.

Build it short.
Build it long.
Build it absurdly quiet.
