Practice Rounds That Let You Train Without Consequences
You wouldn’t carry a tool you’ve never tested. Rubber rounds let you put shots through your Streetwise Heat Launcher in a controlled setting — backyard, range, wherever you can safely practice — without deploying pepper powder or worrying about irritant clouds drifting back toward you.
They’re simple, affordable, and they work.
Who These Rubber Balls Are For
New Heat Launcher owners who want to understand how their device fires before loading live pepper rounds. Also useful for experienced users who want to maintain proficiency without burning through their pepper ball supply.
If you train periodically — and you should — rubber rounds are the most economical way to do it.
Is This the Right Choice for You?
Choose Rubber Balls if you want:
- The most affordable practice ammunition for your Heat Launcher
- A no-irritant option you can use indoors or in shared spaces
- Blunt impact feedback that helps you gauge aim and distance
Consider something else if you need:
- Active deterrent capability — PAVA pepper balls are what you want
- Enhanced accuracy for precision training — Quicksilver rounds offer better ballistics
What You Get
Each round is a solid rubber ball sized to .50 caliber specifications for the Heat Launcher’s barrel. The rubber compound is durable enough to maintain its shape through the CO2 propulsion system while soft enough to reduce the risk of serious injury compared to metal projectiles.
On impact, you’ll feel and see where the round hits, which is the whole point of training ammunition. It gives you tactile feedback on your aim, helps you understand projectile drop at distance, and lets you practice the mechanics of loading, aiming, and firing without any complications.
These rounds are compatible exclusively with the Streetwise Heat Pistol Launcher. Don’t attempt to use them in other devices.

Will rubber balls damage walls or furniture if I practice indoors?
They can leave marks and potentially dent softer materials like drywall. CO2-propelled .50 caliber rounds carry enough energy to cause minor damage to household surfaces. If you practice indoors, use a proper backstop — a thick blanket hung over cardboard works in a pinch. Better yet, practice outdoors where you have more room and fewer things to damage.
Are these the same as paintball rounds?
No. Paintball rounds are gel-filled and designed to burst on impact. These are solid rubber and do not burst. They’re sized for the Streetwise Heat Launcher’s .50 caliber barrel, which is different from standard paintball calibers. Do not interchange ammunition between systems.
How do rubber rounds compare to Quicksilver for training?
Rubber rounds are simpler and cheaper — solid rubber, no hybrid construction. Quicksilver rounds have a stainless steel core with ABS casing, which gives them slightly better aerodynamics and accuracy. If you’re focused on building basic familiarity, rubber is fine. If you want more precise accuracy training, Quicksilver is the step up.
