Overview

Designed as a low-profile control point for standard M-LOK handguards, this accessory places a rounded stop between the index and middle fingers rather than at the rear of the support hand. That forward placement helps keep the hand from sliding too far on shorter handguards and leaves room for position changes when moving into kneeling or prone shooting. Its minimal shape keeps the setup compact while still giving a clear reference point for consistent hand placement. At 0.85 inches high, 0.50 inches wide, and 0.4 ounces, it adds function without much bulk.

Pros

  • Low-profile, minimal control accessory for standard M-LOK handguards
  • Rounded profile is designed to sit between the index and middle fingers
  • Forward placement helps keep it out of the way during kneeling or prone transitions
  • Can serve as a forward limit on shorter handguards
  • Compact size and 0.4 oz weight keep added bulk minimal

Considerations & Trade-offs

  • Designed as a minimal control accessory, so it offers less surface area than a larger hand stop or foregrip.
  • Its rounded profile is intended to sit between the index and middle fingers, which may feel different from more traditional rear-positioned hand stops.
  • It is made for standard M-LOK handguards only, so compatibility depends on that mounting system.
  • At 0.85" high, 0.50" wide, and 0.4 oz., it adds only a small amount of bulk, which is useful for keeping the setup compact but limits how much purchase it provides.

Frequently Asked Questions

What handguards is the Arisaka M-LOK Finger Stop compatible with?

It fits standard M-LOK handguards.

Where is the Finger Stop meant to sit on the handguard?

It is designed to be positioned between the index and middle fingers, typically farther forward on the handguard than a rear-positioned hand stop.

Will it interfere when moving into kneeling or prone positions?

The product description says its forward placement is intended to stay out of the way when transitioning to kneeling or prone, since support-hand placement often moves rearward in those positions.

What is the purpose of the Finger Stop?

It is a low-profile control accessory that can serve as a forward limit to help keep the hand from slipping off shorter handguards onto a hot barrel or suppressor, and it can also be used as a barricade stop.

What size and weight information is provided?

The listed specifications are height 0.85 inches, width 0.50 inches, and weight 0.4 oz.
