Tuning Extended reservoir Benjamin bulldog

You can get the 100cc shroud length reservoir extension from pitbull air for $75 and get about 5 more shots

That's spot on

But you loose your lower picatinny rail and ypu have to cut a portion of the plastic frame to allow the extended reservoir to fit.

Without the pitbull moderator the reservoir extends about 4.5" past te barrel.

With that said I like mine.

In factory form with extended reservoir you can probly get 10 more shots

Drilled transfer port and a tighter hammer spring you can expect 5 more shots.

Best choice then becomes moderators like a donny fl. I have the extended reservoir and donny FL emperor plus an extender tube which takes it to ridiculous long. The report from moving air is a low hiss, the loudest part is the internal mechanics of the bulldog. Makes it garage friendly for running tests.
