CMMG ZEROED Mk4 Ambidextrous AR-15 Charging Handle Assembly - Aluminum Black

The CMMG ZEROED Mk4 ambidextrous AR-15 charging handle assembly brings a refined approach to one of the most frequently manipulated components on your rifle. Built on proven ambi design principles, the ZEROED Mk4 strips away unnecessary bulk while keeping the features that matter: low-profile handles that won't snag your optics or get in the way of your shooting hand, paired with intuitive operation from either side of the receiver. If you run a modern tactical AR-15, lefty or righty, this is the kind of upgrade that makes the gun feel more instinctive in your hands.

Machined from 7075 aluminum and finished in black, the ZEROED Mk4 is built to handle rough use. The design prioritizes a secure grip whether you're charging under pressure, wearing gloves, or dealing with a mounted optic that eats up receiver real estate. The symmetrical handle geometry means you'll actually want to use this from both sides—no awkward compromises or sacrifice to either hand's ergonomics.

This is a drop-in assembly ready for any AR-15 platform rifle. Whether you're setting up a 3-gun competition gun, a hunting rifle, a home defense carbine, or a range tester, the ZEROED Mk4 handles all of them equally well. It's the kind of part that quietly improves your weapon handling every single time you charge the bolt.
