Platforms & Power Sources

You’ll find BB pistols, BB rifles, as well as consumables like BB gun magazines and BB ammo. Each platform offers unique benefits depending on your shooting style:

  • CO2 Blowback Pistols: Realistic slide action with added recoil feel. Best for handling drills, though expect higher CO2 consumption.

Meet the Umarex Colt M45 CQBP CO2 Blowback Steel BB Gun as an example.

  • CO2 Non-Blowback Pistols: More efficient, with steadier FPS and longer cartridge life. Excellent for practice sessions.

  • Spring / Multi-Pump Rifles: Simple and reliable. Operate without gas, ideal for single-shot or small magazine use. Popular for low-maintenance shooting.

  • Magazines: Always verify pistol vs rifle compatibility, feed style, and capacity before ordering replacements.

Types of BB Ammo

Not all BBs are created equal. Depending on your platform and practice environment, different finishes and materials can make a difference in performance and safety:

  • Zinc-Plated BBs: Corrosion-resistant and cost-effective, a solid choice for everyday plinking.
  • Copper-Plated BBs: Smoother feeding and reduced barrel friction, often preferred for CO2 pistols and rifles.
  • Steel BBs: The classic option for most 4.5mm calibre BB guns, widely available and consistent in weight.
  • Dust Devil BBs: Frangible design that shatters on impact, reducing ricochet risk and making them ideal for indoor or close-range shooting with targets & traps.

CO2 & Cold-Weather Notes

CO2 BB guns rely on compressed gas. Performance drops as temperatures fall, making it important to keep 12g cartridges warm before use.

In winter, you may notice reduced FPS and slower cycling. Plan for extra cartridges if you’re shooting outdoors in Canadian conditions.

FAQ's

BB vs pellet vs airsoft—what’s the difference?

BB guns shoot round 4.5mm steel BBs (.177 calibre), best for plinking and basic practice. Pellet guns use shaped lead or alloy projectiles for higher precision.

Airsoft uses 6mm plastic BBs designed for skirmish games and is not interchangeable with steel BB platforms.

Blowback vs non-blowback—what should I choose?

Blowback CO2 pistols replicate real firearm slide movement, adding realism for drills but consuming more gas.

Non-blowback designs maximize efficiency, offering longer CO2 life and consistent FPS, making them ideal for extended practice sessions.

Which BB ammo should I use?

Always use .177 calibre (4.5mm) steel BBs designed for your gun. Premium-polished BBs reduce jamming and wear.

Avoid mixing brands if your magazine tolerances are tight, and never substitute airsoft plastic BBs or pellets.

Magazine vs single-shot—which is better?

Magazine-fed BB guns allow faster follow-up shots and more realistic reloads.

Single-shot or small reservoir systems offer simplicity, reduced jamming risk, and are common in spring or pump-action rifles.
