The Knockout XX-100 is a Nerf blaster that was released on October 1, 2019[1], under the RIVAL series.

It comes packaged with two High-Impact Rounds and instructions.


The Knockout XX-100 is a small blaster that uses a breech system. The breech can be accessed by pushing the breech lever and the breech will open.

Just behind the breech is a tactical rail. Under the tactical rail is the breech lever. Upon pulling the breech lever, the spring-loaded breech opens automatically for loading and must be manually closed. In front of the firing trigger is a place to store four High-Impact Rounds, two on each side of the Knockout. Under the trigger there is a safety switch.

The blaster itself is primed by a small priming rod, resembling that of external mechanism blasters such as the Jolt EX-1. However, unlike external mechanism blasters, the priming rod is not directly connected to the plunger rod; it needs to be pushed back up to fire the blaster.

It advertises a firing velocity of eighty feet per second (twenty-four meters per second).

Blaster sets

  • Despite being released in 2019, the Knockout's name marks it as a 2020 blaster.
  • The Knockout is the first non-cross-promotional RIVAL blaster to not be named after any sort of deity or mythological hero.
  • The Knockout and the McCree Blaster share the smallest firing capacity out of any RIVAL blasters.
  • The blaster can load and fire two rounds at once, with considerable drops to firing power.[1]
  • This blaster resembles the N-Strike Mega BigShock in both size and appearance. However the mechanism for the blaster is entirely different.
  • Some distributor websites denote the Knockout as the Pontus XX-100 (named after Pontus, a pre-Olympian sea god in Greek mythology). It is speculated to be an old name, but was later changed as a way of rebranding the RIVAL series and drifting away from names of characters from Greek/Roman mythology towards fighting-related terms.
