Magpul
Low-profile rubber-like ladder cover for exposed 1913 Picatinny rails.
The Magpul Ladder Rail Panel is the simplest way to make exposed 1913 Picatinny rails less sharp and less heat-prone. It sits inside the rail channels rather than wrapping around the rail, so it preserves a very low profile and can be cut to fit around lights, grips, and sling mounts.
This is a legacy quad-rail and clone-build accessory. It belongs on KAC RAS, RIS II, and other Picatinny-heavy rails, not on modern M-LOK handguards.
Add the Magpul Ladder Rail Panel to your build and see how it enhances your platform.
