Magpul M-LOK Index Stop

Description Magpul M-LOK Index Stop The Magpul M-LOK Index Stop is the most minimalist of Magpul’s three new May 2026 M-LOK control accessories — a half-slot hand stop designed to give the index finger a defined reference point on an octagonal aluminum handguard without adding meaningful bulk, weight, or profile to the build. Magpul designs the Index Stop around the index finger as a primary contact point, providing a ridged surface that keeps the finger consistently positioned on the handguard during firing. Because consistent hand indexing directly affects grip repeatability, the Index Stop helps shooters return to the same firing position shot after shot without conscious adjustment. The ridged surface adds texture for positive contact under recoil, moreover the half-slot footprint means it occupies minimal real estate on the handguard — preserving space for lights, lasers, or other accessories without compromise. Magpul molds it from their proprietary high-strength polymer and includes 4140 chromoly steel M-LOK hardware with a mil-spec manganese phosphate finish for direct slot mounting without a Picatinny adapter. The ambidextrous design works identically for left and right-handed shooters. Key Features — Magpul M-LOK Index Stop Half-slot minimalist hand stop — smallest footprint in the May 2026 M-LOK family Ridged surface for positive index finger contact and consistent hand placement Improves grip repeatability and firing position consistency shot to shot Half-slot M-LOK footprint — maximum rail space preserved Ambidextrous — no modification required for left or right hand Magpul proprietary high-strength polymer construction M-LOK hardware included — 4140 chromoly steel, mil-spec manganese phosphate finish Direct M-LOK mount — no Picatinny rail adapter required Weight: 0.35 oz Compatible with octagonal aluminum M-LOK handguards only Black finish Made in the USA New for May 2026 Why the Magpul Index Stop Stands Out Most shooters focus on trigger technique and stance when working on consistency, but support-hand placement is an equally significant variable — and one that’s harder to address because it relies entirely on feel and muscle memory without a physical reference. The Index Stop introduces that reference without requiring the shooter to adopt a new grip technique or add a full vertical grip to the handguard. The half-slot design is a meaningful distinction from the Thumb Shelf and SVG. Where those accessories provide a surface for the thumb or full hand, the Index Stop is specifically for the index finger — consequently, it suits shooters who run a straight thumb position along the handguard rather than a wrapped thumb-over-bore technique. Additionally, because it uses only half an M-LOK slot, it is the most space-efficient control accessory Magpul makes. For shooters running a tight accessory configuration — light, laser, sling mount — the Index Stop adds hand control without displacing anything. Furthermore, at 0.35 oz it adds virtually nothing to the build’s overall weight. For the shooter who wants a definitive hand reference point in the smallest possible package, the Index Stop makes a straightforward case. Ideal Use Cases Improving index finger position consistency on straight-thumb shooting technique Minimalist and lightweight carbine builds Suppressor-host rifles where handguard real estate is at a premium Competition builds prioritizing weight and balance Shooters wanting a hand reference point without a full vertical grip Technical Specifications Specification Details Manufacturer Magpul Industries Model M-LOK Index Stop SKU MAG1568-BLK UPC 840815151012 Weight 0.35 oz Material Magpul proprietary high-strength polymer Hardware 4140 chromoly steel — mil-spec manganese phosphate finish Surface Ridged for positive finger contact M-LOK Slots Required Half slot Mounting System Direct M-LOK — hardware included Compatibility Octagonal aluminum M-LOK handguards only Orientation Ambidextrous Finish Black — matte Country of Origin USA Release New — May 2026 Compatibility Information Handguard Compatibility The M-LOK Index Stop is compatible with octagonal aluminum M-LOK handguards only.
