DonnyFL | Muzzle Brake Air Stripper Fat Boy Insert Kit | Black
Muzzle Brake Air Stripper Fat Boy Insert Kit | DonnyFL – Air stripper inserts for airgun muzzle brake
This replacement kit contains air stripper inserts for the DonnyFL Fatboy Muzzle Brake, designed to guide airflow around projectiles in air rifles. The kit includes two inserts per calibre for 4.5mm/.177, 5.5mm/.22, and 6.35mm/.25, constructed from bronze material.
Construction and materials
The air stripper inserts feature a bronze construction with a black finish. Each kit contains multiple inserts to accommodate three standard airgun calibres. These are precision-machined replacement parts specifically designed for the Fatboy Muzzle Brake system. Note that these inserts are not compatible with Gold Edition muzzle brakes.
Application and use
These inserts are used in recreational shooting and target shooting applications with air rifles. The air stripper design channels excess air away from the projectile as it exits the barrel, potentially improving accuracy. Selecting the correct calibre insert prevents projectile contact with the muzzle brake interior.
Integration and compatibility
The kit is exclusively compatible with the DonnyFL Fatboy Muzzle Brake and supports PCP and spring-powered air rifles in .177, .22, and .25 calibres. Users must match the insert size to their rifle's calibre for proper function.
Maintenance and lifecycle
As replacement foam components, these inserts require periodic inspection for wear or damage. Regular cleaning helps maintain optimal airflow performance and extends service life.
