The Butler Creek ESC44 is an Element Scope Cap designed as a flip-open objective lens cover for riflescopes with 40-44mm (or up to 40-45mm) objective bells—roughly 1.57–1.73 inches in diameter.
Key Features
- Multi-flex rubber sleeve — Stretchable for a secure, watertight/airtight fit across a range of objective diameters in the 40-45mm class.
- Rugged ridged polymer lid — Tough construction that handles abuse, extreme temperatures, and harsh outdoor conditions.
- Flip-open mechanism — Supports 180° and 270° open positions for quick, one-handed access with a push-button or tab release.
- Modular interchangeable disks (included):
- Black opaque disk — Blocks direct sunlight and reduces glare on the lens.
- Clear disk — Lets you view through the scope (including your reticle) with the cap closed—handy for light rain, snow, or dust without opening it.
- Printable data/dope disk — Customize with your rifle's ballistic information (windage, elevation holds, etc.). Print the template from Butler Creek resources and insert it for quick field reference without needing to open the cap or consult a phone/app.
- Stainless steel hardware — Adds durability and corrosion resistance.
- All-weather performance — Built for hunting, tactical, or range use in varying conditions.
Like the rest of the Element series (including the ESC65 you asked about previously), this cap emphasizes modularity and toughness over basic flip caps. The dope disk is especially popular for precision or long-range shooters.
Who It's For
Ideal for hunters, varmint shooters, or anyone with compact-to-mid-size scopes (common on many .223/5.56, .308, or lightweight hunting rifles with 40-44mm objectives). It pairs well with an ocular/eyepiece cap from the Element line for full protection.
Compatibility Notes
- Objective side only (separate Element caps exist for eyepieces in smaller sizes like 37-42mm or 42-47mm).
- The stretch sleeve accommodates slight variations, but measure your scope's objective bell diameter for the best fit (use calipers or Butler Creek's fit chart for precision).
- Fits approximately 95% of common scopes when sized correctly; always verify with your specific model.
