The insert braces against the inner structure of the handguard at 4 points spaced at 90°, ensuring firm and stable positioning.

Frequently Asked Questions (FAQ)

What Is the RetroArms Outer Barrel Centring Insert Used For?

The insert is designed to eliminate play between the outer barrel and handguard. It reduces unwanted barrel movement and helps stabilise it, which is particularly useful with longer barrels or heavier setups.

Which Handguards Is the Insert Compatible With?

The centring insert is designed for RetroArms CNC M-LOK handguards from the 2025 model range. The manufacturer does not specify compatibility with other types of handguards.

How Does the Insert Stabilise the Outer Barrel?

Inside the handguard, the insert rests against its structure at 4 points spaced 90° apart. This helps keep the outer barrel more securely seated and reduces its movement inside the handguard.

Will the M-LOK Slots Remain Accessible After Installation?

Yes. This version of the centring insert is designed so that it does not extend into the axis of the M-LOK slots. The M-LOK slots therefore remain accessible for mounting accessories at the point where the insert is installed.
