Shield Arms PMAG Gen 3 +5 Extension – Black

The Shield Arms PMAG Gen 3 +5 Extension increases capacity of Magpul PMAG Gen 3 5.56 magazines by five rounds. Compatible with both windowed and non-windowed PMAGs, this extension replaces the factory floorplate to convert a standard 30-round magazine into a 35-round configuration. Ideal for competition shooters, range training, or situations where extended capacity is permitted and practical.

Machined from aluminum with a Type III hard-anodized black finish for corrosion resistance and durability. Installation is straightforward—remove the factory baseplate, insert the included extension spring, and attach the Shield Arms extension. No permanent modification to the magazine body required. Note: Extended magazines may not be legal in all jurisdictions. Verify local and state laws before purchase.
