Product DescriptionThe Magpul PMAG 30 AR 300 B GEN M3 is a dedicated 30-round polymer magazine engineered specifically for rifles chambered in .300 AAC Blackout. Its internal geometry is optimized to support the differing cartridge and bullet-profile geometries common to 300 BLK, improving feeding reliability compared to using standard 5.56 magazines. To help prevent dangerous cross-loading, it features distinct visual and tactile differences from other PMAGs, along with aggressive front and rear texture for positive handling. Built with next-generation impact- and crush-resistant polymer and a slim, easily removable floor plate, this magazine is designed for dependable use on the range or in the field.Product HighlightsPurpose-designed 30-round magazine for .300 AAC Blackout (300 BLK) rifles with optimized internal geometryDistinct rib design and tactile/visual indicators help reduce the risk of dangerous cross-loading with 5.56 magazinesNext-generation impact- and crush-resistant polymer body for durabilityAggressive front and rear texturing for secure grip and fast handlingRemovable slim floor plate for easier cleaning and maintenanceSpecsBrand: Magpul IndustriesModel/Series: PMAG 30 AR 300 B GEN M3Type: Rifle magazineCaliber: .300 AAC Blackout (300 BLK)Capacity: 30 roundsColor/Finish: BlackMaterial: PolymerCompatibility: AR-pattern rifles chambered in .300 BlackoutManufacturer Part Number: MAG800-BLKUPC: 840815117223Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
