Proton Rounds

(2 customer reviews)


SKU: N/A Category:


The only foam High Impact Round ammunition sourced and tested by active members of our community, “Proton Rounds,” were designed with our hobby in mind.  They have a very consistent density from ball to ball so there should be less extra squishy/extra firm balls in each batch which leads to more predictable performance than the leading 3rd party brand.  They have a smooth “waxy” finish on the ball so they hold up to repeated uses better.  These balls were produced by FoamBlast for Out of Darts with testing assistance from Luke.  These work best in flywheel blasters and were optimized for excellent performance with the Jupiter and HIRricane.  While they will work in springers, they see less performance than genuine Rival rounds, just as with most aftermarket brands.  For Blasters like the Kronos, Artemis, or Hades, we recommend Genuine Hasbro HIRs.

Pack contains 100 rounds.


Blasters should be modified at your own risk by an adult or with adult supervision. Modification of blasters may increase wear and reduce lifespan of blaster. Always wear eye protection. Never point at someone’s face. By purchasing, you agree that FoamBlast is not responsible for injury or damage caused by misuse or accidental usage.

    I just received my proton rounds! I live in Colorado, so coupled with an altitude about 6000 feet above sea level and how crazy arid it is here, sometimes foamy projectiles… act up. Headshot ammo frequently jams in longer magazines. I am happy to report that protons rounds work in every Nerf Rival springer offering (including the atlas). the colors are vivid and every round is so very consistent. I only have one singular criticism… I NEED more colors!

    I have obtained a few Proton Rounds in each of the three colors available playing with our area Rival League groups in Texas and they perform consistently very well in my preferred flywheel blasters (Nemesis, Prometheus, Khaos, and Zeus). At half the price of brand HiRs and reduced greatly from Headshot which has far less consistency, these are a top pick of only a few available in the market among the Phantom Corps’ rogue specialists. I am about to make my first full order given the high quality Out of Darts and FoamBlast put into this excellent collaborative project for accuracy driven players. Thank you all!
    For future colors choices please consider purple, black, and grey/gray.
