Blaster lasers fire energy bolts at a high fire rate with good projectile velocity, though the user must lead moving targets at longer ranges.
Hyperion Blasters have Reverse recoil, which supports sustained fire of the Blaster's Style and offsets their medium recoil. They also have 50% critical hit bonus, or 60% with a Hyperion Stock.
Maliwan Blasters are better at elemental damage, both direct damage and elemental status effects. Their continuous damage bonus also works as sustained fire will cause each future bolt to inflict higher damage than before.
Dahl Blasters launch a 3-round burst when zoomed, which behaves similar to most common Dahl weapons as the laser bolts function like bullets. They also have recoil reduction and the bolts penetrate enemies.
Tediore Blasters have nothing in special., They have low base stats and the reload-throw gimmick which deals a lot more damage in a single burst.
