Why DonnyFL Adapters Matter: PCP airgun owners spend hundreds to thousands on precision rifles. Factory shrouds often don't accept standard suppressors. DonnyFL's extensive adapter library eliminates the "my gun isn't compatible" problem—they've engineered solutions for legacy platforms, budget rifles, and cutting-edge competition guns.
DonnyFL operates as an online direct manufacturer through their Shopify store at donnyfl.com. Orders ship nationwide to customers seeking quieter, more efficient PCP shooting. Products are listed with detailed specifications, compatibility information, and dimensional drawings.
All moderators use replaceable felt inserts and O-ring seals for durability and easy maintenance. The felt absorbs and disperses air noise; the O-rings ensure pressure integrity. Endcaps are interchangeable across compatible models, allowing customers to swap configurations without replacing the entire moderator body.
Thread protection: Most adapters ship with thread protectors to prevent damage during installation. Extended and standard quick-disconnect options accommodate different fill system setups.
Whether you shoot a $500 Benjamin Marauder or a $5,000 FX Impact, DonnyFL has engineered a moderator and adapter to reduce noise signature and improve shot consistency.
