Weight & Length:
The 2240 is a compact CO₂ pistol — heavy or long optics unbalance it. Choose scopes under 15 oz and below 12” length for pistol use.Parallax Setting:
Airgun ranges are short (10–30 yards). Pick scopes with parallax adjustment or fixed settings optimized for 10–25 yards.Mount Compatibility:
The factory Crosman breech is not optic-ready — invest in the steel breech or dovetail mount adapter.Magnification:
For plinking or target practice: 3–9x works best. For pest control: fixed 4x is enough.Eye Relief:
Since CO₂ pistols have no recoil, eye relief flexibility is a bonus for quick sight acquisition.

The Crosman 2240, a CO₂-powered .22 caliber pistol, is known for its modularity and precision potential. However, to truly tap into its accuracy, especially beyond 20 yards, a well-chosen optic is essential.
In this guide, I’ve field-tested and reviewed several scopes and optics setups ideal for the 2240—balancing weight, magnification, parallax range, and mounting compatibility—to help you find the perfect match for your shooting style.

Here’s a quick overview of my top picks for the Crosman 2240 platform:
Each of these optics has been tested for compatibility, weight balance, and accuracy retention on the Crosman 2240 platform, ensuring reliable performance for target shooting, plinking, or pest control.
1. UTG 3-9x32 BugBuster AO Scope
The UTG BugBuster AO is arguably the most popular optic upgrade for the Crosman 2240. Its compact build, adjustable objective, and shockproof design make it perfect for CO₂-powered air pistols and carbines.
Product Specs:
Pros:
Cons:
Glass Clarity & Reticle:
Clarity is crisp up to 7x, with only minor chromatic aberration at full zoom. The illuminated Mil-Dot is bright enough for both indoor and outdoor use.
Eye Relief & Eye Box:
The generous eye relief and forgiving eye box make it comfortable even when shooting off-hand or with custom shoulder stocks.
Durability:
Nitrogen purged and rainproof — it handled my 2240’s CO₂ discharge cooling with zero fogging.
Elevation & Windage Knobs:
Precise, audible clicks (¼ MOA). I tested tracking with a box test at 15 yards, and it returned to zero perfectly.
Magnification & Parallax:
The AO feature (Adjustable Objective) allows for razor-sharp focusing as close as 3 yards—ideal for the Crosman’s typical use range.
Mounting & Accessories:
Comes with quick-detach rings compatible with 11mm dovetail mounts, fitting standard 2240 rails or custom steel breeches.
My Personal Experience:
Mounted on a steel-breech 2240 with 30mm dovetail rings, zeroing took only 10 shots at 10 yards. After 200 pellets, the zero held perfectly.
Online Customer Comments:
Reddit’s airgun community repeatedly mentions the BugBuster as the “go-to” for 2240 carbine builds due to its compactness and reliability.
