Introducing the Overt Industries AR-15 Hard-Line MLOK® Rail System
The Hard-Line MLOK® Rail System was designed with an emphasis on Rigidity, Ruggedness, and Simplicity. 100% Made in the USA, the Hard-Line MLOK® Rail System utilizes a Three Point Mounting System to ensure that the handguard clamps securely to the barrel nut without the possibility of unwanted rotation.
Machined from American sourced 7075 T-6 extruded aluminum, the Hard-Line MLOK® Rail System offers increased strength, rigidity and reduces overall handguard flex by removing often unused MLOK® sections in order to enhance the structure of the rail system. The increase in handguard rigidity reduces handguard flex resulting in a stronger mounting structure for Laser Aiming Devices. We also integrated chamfered serrations to the exterior of the rail system in order to provide maximum grip friction to the end user.
