Moderator DonnyFL Fatboy

This Fatboy moderator by DonnyFL is short, girthy, yet very effective. The large internal chambers and sound dampening material inside, absorb a lot of the sound and significantly decrease the muzzle blast of your airgun.

It’s compatible with calibres of 4.5 mm up to 7.62 mm, DonnyFL ships the Fatboy moderator with 3 interchangeable air strippers, so that each calibre has the least amount of air escaping from the front. The rear cap with ½ UNF thread has been redesigned, it now provides more grip for easy attachment of the moderator.

A 6.25″ extender can easily be added to the Fatboy to increase the internal volume of the moderator, to make your air rifle even quieter.
