Ruger 90403 Magazine Dust Cover 3-Pack for BX-1/BX-15/BX-25 Mags

The Ruger 90403 Magazine Dust Cover protects your valuable BX-series magazines from dirt, debris, and moisture during storage and transport. These precision-molded polymer covers snap securely onto magazine feed lips, preventing contamination that can cause feeding malfunctions in critical moments.

What Makes This Different

Unlike generic magazine covers that rely on loose-fitting designs, these Ruger factory covers feature precise molding specifically engineered for BX-1, BX-15, and BX-25 magazine dimensions. The snap-fit design creates a positive seal around the feed lips while remaining easy to remove under stress. Each cover incorporates reinforced attachment points that resist cracking even after hundreds of installation cycles.
