Premium B5 Rail Cover for M-LOK Systems – Enhanced Grip & Protection

The B5 Systems Premium Rail Cover for M-LOK is a low-profile grip solution designed to improve control and comfort on AR-platform rifles and other M-LOK-equipped platforms. Whether you're running a carbine for duty, sport, or hunting, these rail covers fill gaps in your handguard while adding tactile texture where it matters most. The soft, no-slip material and ribbed design give you dependable grip purchase without bulk, and the heat-resistant construction keeps your hand comfortable during sustained fire or extended range sessions.

These covers use a press-in fit that works with most machined M-LOK rails and polymer handguards, making installation straightforward. Each cover spans 3 M-LOK sections, so you can strategize placement to match your grip technique and shooting style. The heat and chemical-resistant material won't degrade from gun oil, solvents, or barrel-generated warmth—important if you're doing serious training or competition work.

B5 Ships these in packs of four, giving you options to configure both sides of your handguard or arm multiple rifles. They're available in all standard colors to match your aesthetic or camouflage scheme. Lightweight and minimal in profile, they don't add unnecessary bulk to your platform.

Frequently Asked Questions

Will these rail covers fit my handguard?

B5 Systems Premium Rail Covers are designed for most machined M-LOK rails and polymer handguards with standard M-LOK mounting slots. If your rifle uses M-LOK (not Picatinny or KeyMod), these should work. Check your handguard's documentation to confirm M-LOK compatibility.

How many sections of my handguard does one cover fill?

Each rail cover spans 3 M-LOK sections. Standard M-LOK spacing allows you to install them continuously or with gaps, depending on your preferred grip layout.

How do I install them?

These covers use a press-in fit—no tools required. Simply align the cover with your M-LOK slots and press it in. No permanent modification to your rifle.

Are these suitable for high-heat shooting or competition?

Yes. The material is heat and chemical resistant, so it tolerates extended shooting, gun oils, solvents, and the warmth generated during sustained fire or training sessions without degradation.
