DonnyFL Hatsan Bullmaster/Galatian 1/2 x 20 Adapter A35

Unleash the next level of accuracy and stealth with the DonnyFL A35 Adapter—your secret weapon for Hatsan Bullmaster and Galatian airguns. Designed by champion marksman Donny Du, co-owner of Saber Tactical, this 1/2″-20 UNF precision attachment transforms your rapid-fire build into a whisper-quiet powerhouse. Whether you’re chasing personal bests on the competition line or dialing in perfect groups in the backyard, the A35 delivers unmatched consistency, razor-sharp shot feel, and virtually no muzzle disturbance.

At the heart of the A35 is an airflow-optimized design that accelerates pellets more smoothly, slashing backpressure on your action. The result? Crisper shot breaks, reduced recoil, and flawless magazine indexing—even when you’re single-loading for ultra-tight group work. If you push into high-volume fire, a quick swap to a lighter shroud spring (readily available from aftermarket suppliers) fine-tunes indexing for lightning-fast, misfeed-free follow-ups.

Built from aircraft-grade 6061 T6 aluminum, every adapter is CNC-machined to exacting tolerances and finished in a rugged black anodize that stands up to corrosion, bumps, and scratches. The diamond-pattern knurling gives you an iron-clad grip during installation or removal—gloves on or off—so you can customize your setup in seconds. And with compatibility through .30 caliber, you’re equipped for everything from backyard plinking to serious long-range bench rest shooting.

DonnyFL doesn’t just sell gear; we stand behind it. Our dedicated support team of passionate shooters is always ready to help with spring swaps, mounting advice, or tuning tips—whatever it takes to keep you blazing accurate. Upgrade your airgun’s stealth, performance, and reliability with the A35 Adapter and experience why shooters worldwide trust DonnyFL for their silent, high-precision builds.
