10 Best Bb Guns 2025 in the United States

The Sig Sauer Hunting Firearm GEN II Air Rifle is a solid option for those looking for a CO2-powered air rifle with a .177 caliber. Its semi-automatic action and rifled metal barrel support better accuracy and quick follow-up shots, which is great for target shooting or small game hunting. The included 30-round pellet magazine allows for longer shooting sessions without frequent reloads, and the 4x24 scope helps improve aiming precision.

The rifle features a plastic frame and synthetic components, which keep it lightweight, although at 9 pounds it is somewhat heavier than some other air rifles in this class. The ergonomic hunting-style handguard and compatibility with adjustable buttstocks add comfort and control during use. CO2 power typically offers consistent shooting performance for casual and sport use.

This air rifle suits adult users seeking a combination of power, accuracy, and convenience in a hunting-style design; however, those wanting a lighter or more traditional all-metal build might want to consider alternatives.

The Sig Sauer P320 M17 CO2-Powered .177 Cal Semi-Automatic Air Pistol is designed for those who want a realistic training tool or enjoy target shooting. Modeled after the U.S. Army's M17, it offers a genuine feel with a full blowback metal slide and the ability to field strip just like the real firearm. This air pistol uses CO2 as its power source, providing up to 380 feet per second (FPS) velocity, making it quite powerful for a BB gun.

It comes with a 20-round magazine, which is quite generous for less frequent reloading during practice sessions. The barrel is made of metal, ensuring durability, while the frame is plastic, making it lightweight at 2.1 pounds, but potentially less robust over time. The build includes an accessory rail for adding optics or other attachments, and it's reflex sight ready, which is great for customizing your shooting experience.

The all-plastic frame might not feel as premium to some users compared to metal-framed alternatives. Additionally, users need to purchase CO2 cartridges separately, which means ongoing costs. It's a solid option for both beginners and seasoned air gun enthusiasts looking for a reliable semi-automatic BB pistol with realistic features.

The Gamo Varmint Air Rifle is a solid choice for those interested in a .177 caliber air rifle with decent power and accuracy. It uses a spring-piston mechanism, which means it doesn’t require batteries or gas, making it reliable and simple to maintain. This rifle can shoot pellets up to 1250 feet per second, providing enough velocity for small target shooting and pest control.

The single-shot, breakbarrel design requires you to load one pellet at a time, which might slow down rapid firing but helps increase precision. A nice bonus is the included 4x32 scope, which is suitable for beginners to improve aiming, and the synthetic stock with raised cheekpieces offers comfortable handling. The build quality mixes a metal barrel with a plastic frame, keeping the rifle lightweight but possibly less durable than all-metal models.

The package also includes a pellet pen for easy pellet handling. This rifle is best for hobby shooters, beginners, or those looking for an affordable air rifle for small game and target practice. For those interested in high-speed shooting or larger caliber power, other options may be more suitable.
