If you run Magpul Gen M3 PMAGs, this is a no-nonsense upgrade that actually does something: +2 rounds, better grip for reloads, and a treaded base that works like a small monopod when you’re down in prone. It’s low-profile, doesn’t turn your mag into a brick, and it’s built to be used—not admired.
You’re getting a 3-pack of high-impact injection-molded polymer baseplates in matte black.
