Overview

The Magpul M-LOK Index Stop is the smallest control accessory in this release and targets shooters who want a defined reference point without changing the overall feel of the handguard. The stop occupies only half an M-LOK slot and protrudes just 1/8 inch above the rail, the same height as Magpul's Type 2 M-LOK Rail Covers, so it integrates seamlessly into a handguard already running rail covers without creating an obvious step in the grip surface. The primary use is giving the support-hand index finger a consistent landing point, which naturally positions the rest of the hand around it.

The safety benefit matters as much as the ergonomic one: a defined index stop reduces the risk of the support hand creeping forward toward the muzzle during extended courses of fire or under stress. Ridged texture on the front and rear surfaces provides positive feedback against the fingertip without adding bulk or snagging on barriers. The accessory is ambidextrous and mounts directly to octagonal aluminum M-LOK handguards via standard M-LOK hardware.

Real-world use places the Index Stop opposite the larger AFG-style hand stops and vertical foregrips in the same lineup. Where the Magpul Hand Stop Kit gives the entire support hand a forward block, the Index Stop only provides a fingertip reference, which suits shooters running C-clamp or modified grip styles who want to keep their hand extended without changing the contour of the rail. At $19.95 MSRP, the Index Stop is the most affordable accessory in the May 2026 Magpul M-LOK release.

Key Features

  • Half-slot M-LOK footprint, smallest in the Magpul lineup
  • 1/8 inch protrusion matches Type 2 M-LOK Rail Covers for integrated profile
  • Ridged front and rear texture for positive fingertip feedback
  • Ambidextrous design for left or right-handed shooters
  • Reduces risk of support hand creeping forward toward the muzzle
  • Direct M-LOK attachment with no adapter required
  • Made in USA

Pros

  • +Lowest profile control accessory in the Magpul M-LOK lineup
  • +Matches Type 2 Rail Cover height for a seamless handguard surface
  • +Half-slot footprint barely consumes rail real estate
  • +Most affordable in the May 2026 release at $19.95 MSRP
  • +Provides a defined hand-position stop without the bulk of a full hand stop

Cons

  • Octagonal aluminum M-LOK handguards only, not for round or polymer rails
  • Fingertip-only reference may be too subtle for shooters used to a forward block
  • Polymer construction is less durable than machined aluminum alternatives
  • Not a barricade brace point, the protrusion is too small to load against
