DonnyFL Fatboy Air Stripper Insert Kit

The DonnyFL Fatboy Air Stripper Insert Kit is an original upgrade designed specifically for the DonnyFL Fatboy Muzzle Brake. While the Fatboy Muzzle Brake is supplied without air stripper inserts, this kit allows you to install interchangeable inserts that help manage the airflow as the pellet leaves the barrel. The result is a configurable muzzle brake that can easily be adapted for different airgun calibres.

Manufactured from durable aluminium with an attractive bronze anodised finish, the inserts are precision-machined to ensure an accurate fit. The included Delrin installation tool makes changing inserts quick and straightforward without damaging the components.

Whether you use several calibres or simply want to complete your Fatboy Muzzle Brake, this genuine DonnyFL kit offers a practical and easy-to-install solution.
