First, I'm sorry my English is not good... :(
I want to boost power for my benjamin bulldog .357 bullpup, I know that I can boost power by replacing a larger diameter transfer port, but I don't know that 0.270 I.D. is it right or not？
And I want to find stiffer hammer spring for my benjamin bullpup.
Where can I get the transfer port and stiffer hammer spring? I can't find it from ebay...
Who can help me ?
Thank you so much!

Howdy from Texas, I have a VERY modified Bulldog and will be glad to help you out. In fact in fact I'm working on building some upgrades to sell in the very near future. Mainly a barrel support that doubles as a Moderator.
Max Transfer port size for the Benjamin is .277in without offsetting or slotting the bore with a mill. There is no port to buy, it is just something that will have to be drilled out.
As for a heavier spring, I really don't think you need that. I have found that the stock spring with the adjuster turned all the way in and then back out about 2.5 turns is a great spot to start tuning from.
I've ordered some new o-rings for mine that i will be installing and plan on doing a short video while i have it apart.

I am looking forward to your video very much.

Jerry, it doesn't work like that.
You can't just buy modified parts. The parts being modified are integral to the gun itself.
You have 3 choices.
1. Modify the gun yourself
2. Send your gun to someone to have it modified.
3. Buy an already modified gun.

Right after the Bulldog hit the market I posted all of the info you need to know on my website including photos of the parts to modify. You don't need a stronger spring, just a few simple mods and it will shoot a LOT better. https://www.magnumairpower.com/gun-gallery.html (https://www.magnumairpower.com/gun-gallery.html)
I don't sell any parts for this gun currently, just offering info.
