As interest in tactical play continues to explode, new users often ask a common question:
Can airsoft BBs be used in gel blasters?
The short, definitive answer is: No, and doing so can damage your gear—or worse, create serious safety hazards.
In this article, we break down exactly why these two ammo types are not interchangeable, covering the technical, safety, and legal implications. If you're considering mixing them, read this first.
Why It’s Not Safe (or Smart) to Use Airsoft BBs in Gel Blasters
1. Material & Hardness
| Ammo Type | Material | Hardness | Safe for Indoor Use? |
|---|---|---|---|
| Gel Balls | Water-filled hydrogel | Soft | ✅ Yes |
| Airsoft BBs | Solid plastic | Hard | ❌ Risk of damage |
Gel balls are soft, biodegradable beads made of water-absorbing polymer. They explode harmlessly on impact.
Airsoft BBs are hard plastic spheres. Shooting them from a gel blaster—designed for soft ammo—can cause internal breakage or misfire.
2. Size & Barrel Compatibility
-
Gel balls: typically 7–8mm after hydration
-
Airsoft BBs: fixed at 6mm diameter
Most gel blasters are designed with slightly larger barrels to accommodate expanded gel balls. Airsoft BBs may rattle or jam inside, ruining accuracy—or worse, shattering internal components.
3. Pressure & Power Systems
Gel blasters generally operate at lower pressure than airsoft guns. Their springs, barrels, and compression chambers aren’t built to fire hard plastic ammo. Firing BBs can:
-
Destroy your gearbox
-
Warp or break the inner barrel
-
Cause unpredictable ricochets indoors
Can You Modify a Gel Blaster to Fire BBs?
Technically, yes—but it’s a terrible idea unless you're a technician and willing to fully rebuild the blaster:
-
You’d need to replace:
-
The inner barrel
-
Hop-up system (to apply backspin)
-
Powertrain and gearbox
-
-
You'll void any warranty
-
It may become illegal in your area due to realistic firearm laws
Verdict: Don't. Just buy an airsoft gun if you want to shoot BBs.
Can Airsoft Guns Shoot Gel Balls?
Also no.
Gel balls are too soft and large. Inserting them into an airsoft gun can lead to jamming, inconsistent velocity, and risk of internal leaks or burst chambers.
Note: Some airsoft-style looking guns in the gel blaster world are often mistaken for airsoft guns. Always check specs before attempting any modifications.
Legal Issues: Mixing Ammunition Can Be a Crime
In some regions (e.g., parts of Australia or certain U.S. states), modifying toy firearms to fire incompatible ammunition can make your equipment:
-
Restricted or illegal
-
Classified as a replica or real firearm
-
Subject to fines or confiscation
Always check local gel blaster and airsoft laws before attempting any modifications.
The Bottom Line: Don’t Cross the Streams
| Question | Answer |
|---|---|
| Can you use Airsoft BBs in a Gel Blaster? | ❌ No |
| Can you use Gel Balls in an Airsoft Gun? | ❌ No |
| Should you modify either to fit the other? | ⚠️ Strongly discouraged |
| What’s the best practice? | ✅ Use the correct ammo for each platform |
Stick to your lane. Use gel balls for gel blasters, and BBs for airsoft guns.
Each system is designed for optimal performance and safety within its category.
