ERGO WedgeLok M-LOK Rail Cover 4-Pack Black – Slot Cover Grip

Description

Bare M-LOK slots do a great job holding accessories, but they don't give your hand much to hold onto. The ERGO WedgeLok Rail Covers solve that. These molded Santoprene covers drop into unused slots and turn a slick handguard into something you can actually grab with confidence, whether your hands are sweaty, gloved, or half-frozen.

What Sets the WedgeLok M-LOK Cover Apart

The WedgeLok name comes from how these lock down. Instead of just filling the slot, the wedge design snaps in and stays put, so you don't get any shifting or wiggle when you're bearing down on the forend. That gives you a solid platform to apply real grip pressure. The Santoprene material is a rubbery compound that resists heat and chemicals, which matters when your handguard is sitting close to a hot barrel or getting hit with cleaning solvents.

Sizing and Fit on Your Handguard

Each cover measures 6.25 inches long and 5/8 of an inch wide, spanning four M-LOK slots. The rubber is easy to trim with a sharp blade if your rail sections are shorter, so you can dial in the exact length you want rather than being stuck with a fixed run. With four covers in the pack, most builders have enough to run coverage down the sides and bottom of a standard AR-15 handguard.

Grip You'll Notice, Weight You Won't

The outside face carries an aggressive, non-slip texture that adds purchase without turning into sandpaper on your palm. They sit low and stay lightweight, so they add function without bulking up your rail or throwing off the balance of your rifle. Folks who run them tend to like how they round out the profile of a slim handguard and put grip exactly where the support hand lands. They also double as a handy heat shield near the gas block. Available here in black to blend in with just about any build.
