Pyramydair Bulldog "Power Upgrade"?

[GA_LeadHead]

Does anyone know what the Pyramyd air $150 "Power Upgrade" add-on service for a Benjamin bulldog is exactly? What are they doing to modify it?

Claim is that it will boost fpe up to 30lbs depending on ammo.

Just curious as to what you guys know or think they are doing.



Thanks.

I would guess, hammer spring and opening up the transfer port, but thats just a guess. Call em they will tell you.

Saw that upgrade option the other day and was wondering this myself.

They are only Drilling a bigger hole in the barrel and removing the transfer port. Sometimes you'll see a burr created from it that will hurt accuracy.
