Outer barrel centering insert for RetroArms M-LOK handguards 2025 in the solid version is designed to eliminate barrel movement inside the handguard. It braces against the internal structure at four diagonal contact points and stabilizes the barrel especially in longer configurations. A simple upgrade that improves shooting consistency.
Solid RetroArms centering insert is intended for RetroArms CNC M-LOK handguards models 2025. Its purpose is to remove play between the outer barrel and the handguard, which can negatively affect accuracy, especially with longer barrels or heavier builds. The insert braces against the inner structure of the handguard at four diagonal points, ensuring firm and stable positioning. Installation is simple and does not require any permanent modification of the handguard. The solid version occupies the axis of the M-LOK slots, which will therefore not be usable at the installation point.
