Detailed Reviews: 5 Best Scope for Diana Chaser of 2025

1. UTG 3-9x32 BugBuster AO

The UTG BugBuster has long been a legend among airgun enthusiasts. Compact yet feature-rich, it offers clear glass, an adjustable objective (AO), and a rugged design that pairs beautifully with the Diana Chaser’s lightweight construction.

Specs

Magnification: 3–9x
Objective Lens: 32mm
Tube Diameter: 1 inch
Reticle: Mil-Dot, Red/Green Illuminated
Parallax: Adjustable (3 yards to infinity)
Length: 8.1 inches
Weight: 13.9 oz

Pros

Exceptional clarity for its size
Compact design perfect for air pistols
Fully multi-coated optics
Comes with QD rings and lens caps

Cons

Slightly heavy for pistol configuration
Illumination battery life could be better

Glass Clarity & Reticle

The BugBuster’s clarity is excellent, with minimal chromatic aberration. The mil-dot reticle allows for precise holdovers, especially when shooting pellets at variable ranges (10–50 yards).

Eye Relief & Eye Box

Eye relief is forgiving—around 3.2 inches—which works well on the Diana Chaser rifle setup. The eye box is comfortable at 4–6x magnification but tightens slightly at 9x.

Durability

Despite being an airgun-friendly optic, it’s nitrogen-filled, shockproof, and rainproof—proven to handle CO₂ recoil easily.

My Experience

Mounted on my Diana Chaser rifle configuration with 11mm dovetail mounts, it took me only 5 shots to zero at 25 yards. After over 400 pellets, the zero held steady through multiple CO₂ cartridges and outdoor plinking sessions.

Online Discussions

On Reddit and Airgun Nation, the BugBuster is frequently cited as the “go-to” scope for Chaser owners thanks to its short length and precise AO.

Verdict

The best all-around scope for Diana Chaser—great clarity, compact build, and reliable performance.

Glass Clarity & Reticle

The glass performs well for the price, with crisp central resolution. The R4 reticle is simple yet effective for pellet trajectory compensation.

My Experience

I mounted it using medium dovetail rings. After zeroing at 30 yards, it grouped dime-sized clusters consistently with .177 pellets. It’s ideal for Chaser rifle setups, not the pistol variant due to size.
