The Armaspec M-LOK Picatinny Rail Covers, 3-Slot, Black (Armaspec part no. ARM611-3) protect a shorter, 3-slot section of exposed Picatinny rail on an M-LOK handguard from wear, snags, and hot-rail contact during rapid fire. Machined from aluminum and made in the USA, they mount directly to the rail with the included hardware, no separate purchase needed. Finished in black, they blend cleanly with most M-LOK handguard builds. Shooters who only need to cover a short accessory-mounting section, rather than a full 7-slot run, get a properly sized cover instead of an oversized one.
