Magpul's M-LOK Index Stop provides positive positioning and retention for M-LOK mounted accessories. Olive Drab finish. Simple, effective rail management.
The Magpul Index Stop is a precision-engineered accessory designed to organize and secure your M-LOK rail system. This small but essential component serves a critical function: it prevents unwanted movement and rotation of mounted accessories while providing a positive index point for consistent placement.
If you've ever had a light, vertical grip, or other M-LOK accessory shift position during shooting, you understand the frustration. The Index Stop eliminates this problem by providing a mechanical stop that prevents rotation and migration. It's particularly valuable when running multiple accessories on the same rail section.
Install the Index Stop adjacent to your primary accessories to lock them in place. It's an inexpensive insurance policy against equipment drift during training or competition. Whether you're building a precision rifle or a tactical carbine, this small detail makes a measurable difference in reliability and consistency.
