| Feature | FX 3-12×44 | Bushnell 4-16×40 |
|---|---|---|
| Magnification | 3-12x | 4-16x |
| Objective Diameter | 44mm | 40mm |
| Tube Diameter | 30mm | 1 inch / 30mm |
| Low-End Versatility | Higher (3x) | Lower (4x) |
| High-End Magnification | 12x | 16x |
Pro tip: Check your rifle’s mounting height. A 44mm objective may require higher scope rings than a 40mm objective to clear the barrel.
Optical performance and clarity
The FX 3-12×44 typically uses multi-coated lenses in a 30mm tube. This setup prioritizes edge-to-edge clarity and light transmission. The larger 44mm objective gathers more light, which helps in dawn and dusk conditions. You will notice a brighter, wider field of view at the 3x end, making it easier to acquire targets quickly.
The Bushnell 4-16×40 focuses on sharpness at the high end of its range. The 16x magnification is ideal for spotting and precise aiming at extended ranges. However, the 40mm objective transmits slightly less light than the 44mm. At 16x, the field of view narrows, which can make target acquisition slower in the field.
Winner: The FX 3-12×44 for low-light versatility and faster target acquisition. The Bushnell 4-16×40 if you prioritize maximum sharpness at long range over speed.
Pro tip: If you plan to use the scope for hunting in variable light, the 3-12×44’s lower end magnification is more forgiving.

Ease of use and zeroing
The FX 3-12×44’s lower starting magnification makes it easier to use on rifles with shorter barrels or for close-quarters shooting. The 3x end provides a wide field of view, reducing the need to sweep the scope to find a target. The turret caps and locking rings are standard, making zero adjustments straightforward.
The Bushnell 4-16×40 requires a bit more practice at the 4x end, especially if you are coming from a lower-power scope. The 16x end is very sensitive to eye relief and breathing control. However, the Bushnell’s tactile dials are easy to read and adjust in the field.
Winner: The FX 3-12×44 for beginners and general-purpose users who want speed and simplicity. The Bushnell 4-16×40 if you are already experienced with higher magnifications. It helps to understand are banner scopes good before going further.

Value and availability
The FX 3-12×44 is often positioned as a value-oriented scope. You get a lot of optical capability for the price, making it attractive for shooters on a budget who do not need the absolute highest magnification. The Bushnell 4-16×40 is also a budget-friendly option, but its value proposition is centered on reliability and brand trust rather than maximum optical versatility.
If you can find the specific FX 3-12×44, it competes well on specs. However, if it is out of stock or overpriced, the Bushnell Banner line (like the Banner 2) offers a comparable 4-16×40 experience with a more consistent supply chain.

Which should you buy?
- For general-purpose shooting: Choose the 3-12×44. The lower 3x magnification and wider 44mm objective make it faster and more versatile for hunting and varmint control.
- For long-range precision: Choose the 4-16×40. The 16x magnification gives you the extra detail needed for distances beyond 500 yards.
- For beginners: Start with the 3-12×44. The wider field of view and lower starting power are more forgiving as you learn to work the scope.
- For strict budgets: Compare street prices for both. The Bushnell often has better availability and warranty support, which can save money in the long run if the scope needs service.

Frequently asked questions
Is the Bushnell 4-16×40 good for hunting?
Yes, it is a solid choice for hunting at mid-to-long ranges. The 16x magnification helps with target identification at distance, but the 4x start is less forgiving for close-quarters situations compared to a 3-12×44. If you primarily hunt in thick brush where close-range shots are common, the 3-12×44 is more versatile.
What is the difference between a 30mm and 1-inch tube?
A 30mm tube is slightly wider than a 1-inch (25.4mm) tube. This allows for more travel in the turret adjustments, which is beneficial for long-range shooting. A 1-inch tube is more common on budget scopes and offers sufficient adjustment range for most hunting and general-purpose use. Ensure your scope rings match your tube diameter. We cover comparing budget scope durability in a guide of its own.
Which scope has better low-light performance?
The FX 3-12×44 generally has better low-light performance because of its larger 44mm objective. It gathers more light than the 40mm objective on the Bushnell. This results in a brighter image during dawn and dusk shooting conditions. If you frequently shoot in low light, the 44mm objective is a significant advantage.
