The B5 Systems Rail Cover M-LOK is a low-profile rail cover set designed to add grip, comfort, and heat resistance to compatible M-LOK rail sections. The soft non-slip material and ribbed surface help improve traction without adding much bulk to the front end of a build. Each pack includes four rail covers. Each cover is designed to press into three M-LOK slots, making it a simple way to add texture and hand protection to compatible machined rails and polymer handguards.
