Weapon statistics are currently valid only as of 22.214.171.124 from Early Access. The way weapon data is processed has been changed from this build forward, and as such, any statistical changes can only be surmised through testing and guesswork. Accordingly, this data should be treated as valid unless superseded by evidence to the contrary.
