Magpul XTM Hand Stop Kit AR15/M4/M16 - Gray Polymer Ambidextrous (MAG511-GRY)

The Magpul XTM Hand Stop Kit is a four-piece modular system designed to give AR15, M4, and M16 shooters better control and safer handling of their rifle. Whether you're running drills at the range, setting up a tactical carbine, or working through a practical course, this kit addresses a real problem: where your support hand goes on the rail, and how to keep it away from hot components. Magpul built this with the idea that one solution doesn't fit every shooter or every rail setup—so you get options to dial in what works for your grip and your gun.

The kit includes four pieces: a hand stop, an index panel, a full XTM Enhanced Panel, and a half-length XTM Enhanced Panel. The hand stop itself serves dual duty—mounted on your rail, it acts as both a forward reference point for consistent hand placement and a physical barrier that prevents your hand from drifting too far forward toward the muzzle or front sight assembly. The index and enhanced panels give you flexibility to customize the grip feel and hand position to your preference. All components are made in the USA and feature Magpul's TSP (Tactical Speed Panel) texture, which delivers a secure, no-slip grip surface even when things get wet or your hands are sweaty. The whole kit is lightweight and low-profile, so it won't add unnecessary bulk or snag on gear.

This is the kind of upgrade that pays dividends if you shoot a lot or if you're training seriously. It's not flashy, but it's thoughtfully engineered—the modular design means you can set it up once and leave it, or swap panels around to match your shooting style or new rifle configuration. Available in gray polymer with an ambidextrous design, so it works for both right- and left-handed shooters.
