Are these compatible w/ Nerf Helios?

I don't have a Helios to test, but they are compatible with every blaster that uses Rival rounds that I own.

Are these rounds worth purchasing for a Prometheus? Idk if I should buy 200+ of these rounds if the performance boost is marginal at best

These accuRival rounds have a rubber-like coating on them are much more durable than standard rival. They also have less drop over distances and less curve due to being slightly smaller and having slightly less wind resistance due to the coating. Fps is a tiny bit less than standard rival. They tend to fly farther not straighter. When I ran these through my heavily modified Prometheus I was hitting 120 fps and 10 rounds per second. Almost identical to standard rival. Hope this helps!
