If you are shopping for a BB gun with “bullets,” the ammunition you need is usually called BBs, not bullets. For .177-caliber steel BBs, the Daisy Powerline 426 is best for fast semi-automatic shooting, while the Umarex Glock 19 Gen3 offers a different pistol design and shoots steel BBs at up to 410 fps. The Walther P22 uses 6mm plastic airsoft BBs instead. The Umarex MCP kit and Crosman Copperhead BBs round out the options for buyers seeking a starter package or bulk ammunition.
| Product | Best suited for | Ammo or power detail |
|---|---|---|
| Daisy Powerline 426 | Fast-paced target practice | CO2-powered; 15-shot magazine |
| Umarex Glock 19 Gen3 | Steel BB shooting | .177-caliber steel BBs; CO2 |
| Walther P22 | 6mm airsoft use | Plastic BBs; spring powered |
| Umarex MCP Kit | Buyers seeking an included-supplies kit | Listing identifies BBs, CO2 cartridges, and safety glasses |
| Crosman Copperhead BBs | Stocking up on steel BBs | 4.5mm copper-coated steel BBs |
Daisy Powerline 426 Semi-Automatic BB Pistol

The Daisy Powerline 426 is best for buyers who want a CO2-powered pistol for quick target practice. Its 15-shot magazine and semi-automatic operation allow the user to fire shots by pulling the trigger, and the listed velocity is up to 430 fps. Molded finger grips and an accessory rail are also listed features.
Choose this model if repeated shots and reactive-target practice matter more than a spring-powered design. The listing describes it as suitable for targets such as tin cans or steel plates. A limitation is that the supplied product details do not say whether a CO2 cartridge is included, so check the package contents before buying.
Umarex Glock 19 Gen3 .177 BB Pistol

This Umarex model is best for buyers seeking a CO2-powered pistol that fires .177-caliber steel BBs. It has a 15-shot capacity and a listed maximum velocity of 410 fps. The product information specifies a 12-gram CO2 cartridge as its power source.
Choose it if you want a steel-BB pistol and are prepared to supply the power source. The listing clearly states that the CO2 cartridge is not included, so it is not a complete out-of-the-box setup on that point. Use only the ammunition type specified for the product.
Walther P22 6mm Airsoft Pistol

The Walther P22 is best for buyers specifically looking for a spring-powered airsoft pistol. It is made from high-strength polymer and shoots 6mm plastic airsoft BBs at up to 260 fps, according to the supplied product details.
This is not the same ammunition category as a .177-caliber steel-BB air pistol. Choose the Walther if your intended use calls for 6mm plastic airsoft BBs; avoid treating its ammunition as interchangeable with steel BBs. Its spring power source also distinguishes it from the CO2-powered pistols in this list.
Umarex MCP .177 BB Gun Kit

The Umarex MCP kit is best for buyers who prefer a package listing that includes supplies alongside the air pistol. Its name identifies BBs, CO2 cartridges, and safety glasses as included items, which may reduce the need to source those items separately.
The supplied listing does not provide details such as magazine capacity, velocity, or the quantities of included BBs and cartridges. Compare those package specifics before choosing it over a pistol with more complete specifications. Confirm that its included ammunition matches the gun’s requirements before use.
Crosman Copperhead 4.5mm Steel BBs

These Crosman Copperhead BBs are best for buyers who need a larger supply of 4.5mm steel ammunition. The product information describes copper-coated steel BBs, a flip-top pouring spout, and a bottle containing 6,000 rounds. The coating is intended to keep the BBs smooth and round as they travel through a barrel.
Choose these for a compatible air rifle or pistol that uses 4.5mm steel BBs. They are ammunition, not a BB gun, and they are not the 6mm plastic BBs used by the Walther airsoft pistol. Verify your equipment’s ammunition requirements before loading.
Buying Guide: How To Choose A BB Gun And BBs
Do you need steel BBs or plastic airsoft BBs?
Check the caliber and ammunition type first. The Daisy and Umarex Glock listings specify .177-caliber steel BBs, while the Walther P22 uses 6mm plastic airsoft BBs. These are different products and should not be substituted for one another. The Crosman Copperheads are 4.5mm steel BBs; check that measurement against your equipment’s instructions.
Should you choose CO2 or spring power?
CO2 powers the Daisy Powerline 426 and Umarex Glock 19 Gen3. The Walther P22 is spring powered. Consider whether you prefer the listed CO2-powered operation or a spring-powered airsoft option. Check whether required cartridges are included: the Glock listing says its CO2 cartridge is not included, while the Daisy listing does not specify package contents.
What should you check before ordering?
- Confirm the gun’s required BB material and caliber.
- Check magazine capacity and listed velocity if those details matter to your intended use.
- Review package contents, including CO2 cartridges, ammunition, and safety glasses.
- Use appropriate eye protection and follow the product instructions and local laws. Never aim at people or animals.
