IDL Industries M-LOK Rail Cover – Slim Tread

The IDL Industries M-LOK Rail Cover – Slim Tread is precision-machined from aircraft-grade aluminum to improve purchase and control on M-LOK compatible handguards. The ultra-slim, 1-slot, 2-slot, and 3-slot footprints provide added traction exactly where you need it—while minimizing the increase to the handguard's width.

Finished with a Type III hardcoat anodize, this rail cover is built to withstand heat, abrasion, and hard use while maintaining a clean, professional appearance.
