Umarex G36V Parts compatibility question
 

I purchased a H&K Umarex G36V second hand and I want to replace some older internal parts with newer parts and upgrades. I would like to begin with the hop up kit and tight bore barrel. My question is what other brands will I be able to use as replacement or upgrade parts? Any help will be great.

If you have an idea of the type of build you want, shoot me a pm if you have an idea of parts you want to use

Thanks Zfurlong I'm looking for a good high end hop up system to replace the current one in it., as well as a tight bore barrel.
