Warne 5001 PMAG 556 Magazine Extension, 5-Round, Black Hardcoat Anodized Aluminum, Fits PMAG 30-Round Magazines
Warne Scope Mounts
The Warne 5003 PMAG 556 5-round extension gives you a compact magazine solution for shooters who prioritize capacity flexibility over bulk. This aluminum extension attaches to standard PMAG 30-round magazines, letting you dial down to five rounds for compliance in restricted states, precision rifle matches, or situations where a smaller magazine footprint makes tactical or practical sense. Built from hardcoat anodized aluminum in Flat Dark Earth, it's tough enough for field use and blends seamlessly with modern tactical setups.
If you're running an AR-15 or other 5.56 NATO platform and need the ability to swap between full-capacity and reduced-round configurations without swapping magazines entirely, this extension does the job with minimal fuss. The FDE finish resists corrosion and wear, and the aluminum construction keeps weight down—important when you're stacking magazines in a kit or bag.
This is a straightforward accessory for shooters who understand their local regulations or who want operational flexibility. No complicated installation, no gunsmithing—it's a bolt-on solution that works with existing PMAG 30-round bodies to create a purpose-built five-round mag.
