Higher fire rate can be achieved by tapping the trigger at specific intervals, not quickly tapping the trigger, as the fire rate will be lower.
Pacing shots allows the Bolto to recover from a shot's muzzle climb, improving the accuracy of the following shot.
The innate polarity can somewhat limit elemental modding potential, thus making it a less desirable polarity for elemental modding. If you wish to focus more on elemental damage, then it is recommended to either ignore the polarity or use Forma to turn it into a more suitable polarity.
Bolto can puncture a container and has a 100% chance to destroy the container behind it. The Akbolto does not have this capability.
Upon release, the Bolto created no noise when fired, making it SILENT, but in its upgrade section of the Arsenal its noise level was listed as ALARMING. This was because enemies may still be alerted if the player hits the ground around the target. This was a bug and is no longer the case as of Hotfix: Specters of the Rail 2.2, Bolto (along with Akbolto and Telos Akbolto) are now ALARMING at all times.
