They are tuneable but you will want to make a spring compressor- there is a lot of pre-load on this spring.
You didn't say what you want it for, or what you're willing/going to spend. It is a heavy, powerfulrifle. It can be pretty accurate. You can improve the trigger, but it is not target grade, and there is no GRT-III upgrade. You just smooth out what it comes with.
QB36-2 was my second truespringer. I am not sure it's an upgrade from a BC with Charlie's trigger. Maybe define a purpose and a budget for a second gun, and see what the group suggests, unless you found a swingin' dealon this model?
