The Magpul XTM Hand Stop Kit (MAG511-BLK) is a four-piece, lightweight polymer accessory kit for AR-15, M4, and M16 platforms that mounts directly to 1913 Picatinny rail systems, giving sport shooters and carbine builders a low-profile forward index point and hand stop for improved weapon control and safer muzzle-end hand positioning.

Special Features
- The TSP (Textured Surface Pattern) texture across all kit components gives your support hand a positive, non-slip grip surface without adding aggressive serrations that cut into gloves or bare skin over extended sessions
- The modular four-piece layout lets you configure the kit to suit your handguard rail space, running all panels for a full index and stop setup or omitting panels to fit shorter rail sections
- The index panel design places a physical reference point for your trigger-side and support-side fingers, creating consistent hand placement every time you shoulder the rifle, which benefits both speed shooting and precision work
- The snap-lock panel attachment system requires no tools and no loose hardware, allowing panels to be repositioned or swapped during cleaning or configuration changes in the field
- The hand stop screw-mount hardware secures the primary stop to the rail with a hex-key fastener, keeping it locked in place under hard use without backing out
- The ambidextrous design accommodates left and right-handed shooters with the same kit and no additional parts
Practical Benefits
- The hand stop creates a physical barrier that keeps your support hand from traveling past your intended grip point toward a hot muzzle or front sight assembly, which matters on short-barreled rifles and pistol-caliber carbines where the hands naturally crowd forward
- Competition shooters and carbine course students benefit from the index panel, which trains consistent hand placement across repetitions so your grip lands in the same spot on every drawstroke
- The full kit covers approximately five and a half inches of rail, making it a practical option for mid-length and rifle-length handguards that have open rail sections between other accessories
- The low-profile design does not interfere with iron sights, weapon lights, or lasers mounted further down the rail, so your existing accessory layout stays clean
- Whether you are running a patrol-style rifle build, a home defense carbine, or a competition setup, your support hand gets a dedicated, repeatable reference point that builds muscle memory and keeps your grip exactly where it belongs
The Magpul XTM Hand Stop Kit (MAG511-BLK) in black is a smart addition to any AR-15, M4, or M16 build for the shooter who wants a proven, modular forward control system that improves consistency and keeps hands safely behind the muzzle.
