I don't know if tricky is the right word, but it can be difficult/inconvenient to check headspacing yourself since the necessary gauges aren't cheap. I could be wrong but it's also my perception that not many gunsmiths have headspace gauges for 6.5 G. I'm a DIY kind of guy and have built a handful of ARs, but this is why whenever possible I try to buy a barrel and bolt combo that the factory has checked for headspacing.
Other than headspacing being off, which is virtually unheard of when mating barrels and bolts from reputable vendors (but should still be confirmed), the only thing that you would need to be concerned about in that realm is that you buy the correct bolt for your chamber since there are 2 types of 6.5 G bolts with different bolt face depths. The standard by far is the "type II" bolt which has a .136" bolt face. But this is also hard to screw up since manufacturers and suppliers are mostly pretty good about making clear what type of chamber and bolt they are selling. If you're interested in learning about the chamber and bolt specs there are some good stickies above and the Horde will I'm sure be happy to answer any specific questions or concerns you have when making a purchasing decision.
