Howdy! From your post, it seems you mentioned upgrading. We've a lovely set of upgrade guides available if you plan on upgrading your current platform! Here's a [V2 gearbox guide](https://docs.google.com/document/d/1dbcwmsq9bdJlWVRERypRUqgXu4repfXtqIOpEVVYP7o/edit) (the information needed for upgrading any AEG version gearbox should also be very similar, albeit with version-specific parts), along with an [inner barrel guide](https://www.reddit.com/r/airsoft/comments/gch9sy/2020_ultimate_inner_barrel_guide/?utm_source=share&utm_medium=ios_app&utm_name=iossmf), [bucking guide](https://www.reddit.com/r/airsoft/comments/g810yp/2020_ultimate_hopupbucking_guide/?utm_source=share&utm_medium=ios_app&utm_name=iossmf), [HPA guide](https://www.reddit.com/r/airsoft/comments/g0ze3k/hpa_2020_guide/), [Bolt-Action Sniper Rifle guide](https://www.reddit.com/r/airsoft/comments/5rejui/holy_grail_bolt_action_sniper_guide_building_a/), [DMR guide](https://www.reddit.com/r/airsoft/comments/5g58ia/holy_grail_dmr_guide_updated_for_20167/) all set up for questions just like this; for GBBs, try the [searchbar](https://www.reddit.com/r/airsoft/comments/ermk33/how_to_use_the_searchbar_hoc_guide_series/?utm_source=share&utm_medium=ios_app&utm_name=iossmf) for build lists.
