Azodin kp3 questions and upgrades

[Nymarkerguy]

Recently picked up a used kp3 and going to a weekend pump even in a couple of weeks. It didn't come with anything extra just the marker. I hear people have problems with the reg seat. To avoid issues I'm going to get an oring rebuild kit. Should I buy an extra reg seat also? Or just bring a reg from another marker? Also when I look on azodins site they only have a red rubber replacement that doesn't say what marker it's for and the other is the entire seat with brass. I have heard dye reg seats work also. What do I need? the rubber only or entire piece (brass and rubber). Thanks for any help.

Are there any upgraded woth getting besides the 3d printed slide stabalizer?

Also any hopper recommendations are appreciated.

I think WGP reg seats will work in their regs too.

If you have a decent tight-bore barrel or finger detents there's nothing else you really NEED. I would play with the marker a few times before you sink too much money in upgrades.
