DonnyFL Fatboy Moderator

Wide Body. Serious Suppression. Three Interchangeable Air Strippers.

The DonnyFL Fatboy is a purpose-built airgun moderator engineered for serious sound suppression in a compact, lightweight package. At just 4.25" long and 2" in diameter, the Fatboy's wide-body design maximizes internal volume for effective noise reduction without excessive length — and three interchangeable air strippers let you fine-tune performance for your specific platform and caliber. Compatible with .177 through .30 caliber and extender-ready for shooters who want even more suppression.

Overview

The Fatboy's redesigned 1/2x20 rear cap provides improved grip and easy handling during installation and removal, while the wide 2" diameter body delivers the internal volume needed for effective sound dampening across a broad caliber range. Three included interchangeable air strippers give you the flexibility to optimize performance for your specific airgun setup, and compatibility with DonnyFL's 6.25" extender means you can push suppression even further when the situation demands it.
