What is an M-LOK Handguard?

Benefits of MLok Handguards

Choosing one of the products in our best MLOK handguard list will guarantee you the following advantages

Direct Accessory Mounting

M-Lok allows for the direct mounting of small rails and accessories to your rifle’s handguard, eliminating the need for a heavy Picatinny rail that runs the length of the weapon.

Smoother Texture

Unlike the rough, cheese-grater feel of Picatinny rails, M-Lok features a smoother texture that is gentler on your hands, clothing, and the inside of your rifle case.

Compatibility with Non-Metal Surfaces

M-Lok works well with non-metal mount surfaces, making it an excellent choice for use with polymer accessories.

No Need for Backside Access

When mounting accessories with M-Lok, you don’t need access to the backside of your rail, making it easy to add or remove accessories quickly.

Customizable Placement

M-LOK compatible accessories can be mounted at either end of the system’s elongated slots, allowing for easy customization of accessory placement.

Forward or Rear-Facing Mounting

Accessories can be mounted either forward or rear-facing on the M-Lok system, catering to individual preferences and shooting styles.

No Specific Installation Direction

The M-Lok system doesn’t require a specific installation direction to function properly, providing flexibility and convenience.

Recoil Mitigation and Stability

M-Lok accessories are designed to endure heavy and repetitive recoil, featuring recoil mitigation lugs with full support in all four axes of movement. This prevents shifting due to rough handling or recoil, preserving the stability of your mounted accessories and enhancing shooting accuracy.
