DonnyFL | Suppressor Extender for Fat Boy 2.0 | Black

Fat Boy 2.0 Extender – 7.62cm barrel thread extension

This barrel extender relocates your thread mount 3 inches (7.62cm) forward on air rifles. Made from aluminum with 1/2 UNF threading, it creates additional clearance for mounting suppressors or accessories when barrel threads sit too far recessed. Compatible with .177, .22, .25, and .30 caliber air rifles.

Construction and materials

The extender features solid aluminum construction with a black anodized finish. Total length measures 7.62cm with 1/2 UNF male threads on one end and female threads on the other. This threading standard ensures compatibility with most aftermarket air rifle accessories.

Application and use

Designed for air rifle platforms where the factory thread position prevents proper accessory mounting. Common applications include fitting longer suppressors that would otherwise contact the stock, or achieving a specific visual barrel length for target shooting setups.

Integration and compatibility

The 1/2 UNF thread pattern matches DonnyFL Fat Boy 2.0 suppressors and other accessories using this standard. Suitable for air rifles in calibers 4.5mm (.177), 5.5mm (.22), 6.35mm (.25), and 7.62mm (.30). Thread engagement depth and torque specifications follow standard air rifle mounting practices.
