Review: Nerf Rival Knockout XX-100 – Agile & Fast (90 FPS) Blaster

I got the Nerf Rival Knockout XX-100 ( ) for about $10. I am going to unbox , review, and speed test this new blaster. Overall its a fun well built Nerf foam blaster. It shoots Nerf Rival foam balls very fast at about 90 feet per second! To test this I used a indoor Chronograph tool ( ) to test actual speed of the blaster. Btw, my Youtube vlogs and reviews may also have associated affiliate links to products that may earn from qualifying purchases.

The small blaster comes with a 2 foam balls, but can store 4 balls on each side of the blaster. Overall its quite light weight but heavy duty and noisy due to the spring and slam action to prime the spring. Its a single shot ball and reloading can be done from the breach. I find it easier just to push it in from the muzzle. If your playing with friends, loading from the breach you may be at a disadvantage as it will take more hand actions and time to reload.

Using the Chronograph, the foam balls travel at about 90 – up to 99 feet per second! On average its about 90 – 93 feet per second which is better than the specifications on the box. If i load from the front of the blaster, pushing the foam ball 3 inches into the barrel, it averages the same as feet per second as the loading regularly. However if you only push the ball 2 inches in your velocity will drop below 90 feet per second. I ran 3 tests to confirm this on my chronograph.

The Knockout XX-100 is loud as with most Nerf Rival blasters. Priming, hard plastic, and spring action are pretty noisy. If you are planning to play after hours, your roommates or friends will hear you. Overall the other Nerf Rivals blasters ( ) have strong springs in order to have the higher flight speed.

I found that the Altas XVI-1200 is very accurate without a sight as the barrel positioned near the top of the blaster. It comes with a tactical rail to add accessories This is a great addition to my Atlas XVI -1200 blaster i reviewed and modded earlier this week, as it is agile in tight space play indoors.

Overall Nerf Rival Knockout XX-100 is very fun to play indoors and makes for a great agile blaster in close play. The complex single loading is limiting factor but does not take away much from such a great Nerf Rival blaster. The grip is very big even for adult hands. The spring pull is a bit heavier than a Kronos but should be fine for 14 year olds to adult players.
