Overview of the SENTRY Standard 3mm Scopecoat® Riflescope Covers | Standard 3mm Series
Professional Protection for Your Optics
Your high-end optics represent a significant investment in your shooting performance. The SENTRY Standard 3mm Scopecoat® Riflescope Covers provide the industry-leading defense you need to keep your gear in peak condition. Whether you are navigating dense brush during a hunt or transporting your rifle in a crowded safe, this riflescope cover shields your glass from dust, dirt, dings, and scratches. By utilizing the Standard 3mm Series of protection, you ensure that your aim remains true and your lenses stay crystal clear for every shot.
Advanced Material Engineering
Crafted from a specialized Neoprene and Nylon laminate, these covers do more than just provide a physical barrier. The material, similar to high-quality wetsuits, naturally repels moisture and prevents condensation from forming on your optic. This is particularly valuable when moving between different temperatures in the field, such as exiting a warm vehicle into the cold morning air. The form-fitting design conforms to your specific scope shape, taking up virtually no extra space in your case. As seen in the product photography, the covers feature durable stitching and come in several colors including Coyote Brown, Black, and Blaze Orange to match your tactical environment or safety requirements.
Key Features
-
Premium 3mm Neoprene: Offers a thick, cushioned barrier against impact and scratches.
-
Moisture-Repelling Laminate: The Neoprene and Nylon composition draws condensation and moisture away from the optic body.
-
Flexible Fit: Material stretches approximately 10 percent beyond its resting size to ensure a snug, slip-free grip.
-
Variety of Environments: Available in Black, Coyote Brown, Dark Earth, Natural Gear, and high-visibility Blaze Orange.
-
American Made: Manufactured in the U.S.A. with reinforced stitching for long-term field durability.
-
Lightweight Profile: Conforms to the shape of the scope, making it perfect for use inside hard cases or gun safes.
Compatibility
These covers are designed specifically for optics with standard turret heights. SENTRY defines a standard turret as any adjustment knob that is less than 0.75 inches tall. If your scope features tactical or exceptionally tall turrets, the XP-6 series should be used instead of the Standard 3mm Series.
How to Measure Your Optic
To ensure a perfect fit, follow these four steps before selecting your size:
-
Measure Overall Length: Record the total length of the scope in inches, including any sunshades (Measurement A).
-
Measure Objective Diameter: Record the outside diameter of the objective lens in millimeters (Measurement B).
-
Check Turret Height: Confirm your adjustment knobs are under 0.75 inches tall.
-
Select Closest Size: Compare your data to the list below, keeping in mind the 10 percent stretch factor.
