Description

The Strike Industries PolyFlex Dust Cover for .223/5.56 is a convenient and tool-less dust cover designed for AR-15/M16 rifles. Dust covers serve as protective barriers between the action of the rifle and the elements, preventing dust, dirt, and debris from entering the firearm during operation. Here are the key specifications and information about this dust cover:

Specifications:

Brand: Strike Industries
Platform: AR-15
Model: AR-15 PolyFlex Dust Cover
Material: Polymer
Markings: None
Size: Standard
Color / Finish: Black
Features and Information:

Material: The PolyFlex Dust Cover is made of durable and lightweight polymer. This polymer construction offers resistance to rust and corrosion, making it a suitable choice for outdoor and adverse conditions.
Compatibility: This dust cover is designed to fit standard-sized upper receivers with mil-spec ejection ports. It is compatible with AR-15 Mil-Spec upper receivers and can also fit most billet AR-15 upper receivers, including the Aero Precision M4E1.

Not Compatible: While compatible with a wide range of upper receivers, it is important to note that this dust cover may not be compatible with certain upper receiver models, including the VLTOR MUR (Modular Upper Receiver), ZRO Delta, Lantac Enhanced BCG (Bolt Carrier Group) due to carrier and bolt design, and Bootleg Four Position Adjustable Carrier.

Installation: One notable feature of the PolyFlex Dust Cover is its simple and tool-less installation. It is designed as a one-piece unit that can be easily pushed into place, allowing for a quick installation process. The patent-pending "True Seal" design includes an internal lip that seals the port tightly, providing enhanced protection compared to traditional dust covers.

Removal and Reinstallation: The dust cover is designed for easy removal and quick reinstallation. This can be particularly useful when performing maintenance tasks on your rifle, such as untorquing the barrel nut. It allows you to replace your old stamped steel dust cover with the PolyFlex Dust Cover without the need for specialized tools or lengthy installation procedures.

Overall, the Strike Industries PolyFlex Dust Cover for .223/5.56 offers a user-friendly and cost-effective solution for enhancing the protection of your AR-15 rifle's internals from environmental elements. Its lightweight polymer construction and tool-less installation make it a practical choice for AR-15 enthusiasts and builders.
