Warne 5001 PMAG 556 Magazine Extension, 5-Round, Black Hardcoat Anodized Aluminum, Fits PMAG 30-Round Magazines

The Warne 5001 PMAG 556 magazine extension gives you a quick way to boost capacity on your existing PMAG 30-round magazines. Built from hardcoat anodized aluminum in tactical black, this 5-round extension bolts onto the base of your PMAG 30 to add reliable, accessible rounds without swapping magazines entirely. It's a straightforward accessory for shooters who want flexible load options—whether you're setting up a 3-gun rig, training, or running drills at the range.

Magazine extensions occupy a practical middle ground: they're lighter than carrying multiple full-capacity mags, and they let you keep your magazine platform consistent. The hardcoat anodized finish stands up to holster wear and field conditions, and the aluminum construction keeps weight minimal. This isn't a high-volume magazine—it's a focused capacity bump that pairs with the standard 30-round PMAG you've probably already got in the safe.

Warne Scope Mounts brings nearly 40 years of precision equipment-building to their accessories line, and this extension reflects that same no-nonsense engineering. If you shoot AR platforms and want a modular way to dial in your magazine setup, the 5001 is a dependable choice that won't slow you down.
