Ergo 18-Slot Slim-Line Picatinny Rail Covers, 7-inch, Black, 3-Pack

The Ergo 18-Slot Slim-Line Picatinny Rail Covers in black (Ergo part no. 4379-3PK-BK) snap onto a bare Picatinny rail to protect the shooter’s hand from its sharp edges while adding a more comfortable gripping surface. Ergo is a well-known maker of ergonomic firearm grips and rail accessories, and these slim-line covers run 7 inches long, span 18 rail slots, and come as a 3-pack so a shooter can cover a full handguard’s worth of exposed rail in one order. The low-profile, slim design keeps overall handguard bulk down compared to a thicker rail cover.

Key Specifications

• Each cover spans 18 slots of Picatinny rail, enough to protect a long stretch of exposed rail in one piece.
• Runs 7 inches long, sized for a substantial section of handguard rail.
• Built with a slim-line profile that adds far less bulk than a thicker rail cover.
• Snaps onto standard Picatinny rail sections without screws or tools.
• Made from durable polymer, standing up to repeated handling and weather better than a rubber ladder cover.
• Finished in black to match most factory and aftermarket handguards.
• Sold as a 3-pack, enough to cover multiple rail sections on a single handguard in one order.
• Like most Picatinny rail covers, these snap into place without tools, unlike a screw-on option.
• Covering exposed rail improves comfort and grip traction compared to gripping a bare aluminum rail.
