Rubber rail cover caps for Picatinny and Weaver 20mm accessory rails — a 12-piece pack of modular black caps that snap over exposed rail slots. Use them to cover the empty sections of your handguard, top rail, or side rail so your support hand meets rubber instead of sharp aluminum edges, and to insulate your grip from a hot barrel or suppressor after sustained fire.

Features

• Set of 12 individual rail caps — mix, match, and cut down to fit any gap
• Modular sizing — cover a single slot or link several together
• Black matte finish blends with anodized rails and Cerakote handguards
• Reusable — pull off and re-seat as your accessory layout changes
• Cushions the support hand, dampens contact noise on movement
• Insulates from hot barrel or suppressor heat transfer to the rail

Fit

• MIL-STD-1913 Picatinny rails (0.206" slot spacing)
• Standard Weaver 20mm rails (fit tighter — trim a slot if needed)
• Works on AR-15 quad-rail handguards, M-LOK rails with Picatinny sections, shotgun receiver rails, and Picatinny-compatible optic mounts

Install by pressing each cap over the rail slot until the tabs seat. To remove, pry up gently from one corner with a fingernail or a plastic pick — no tool required.
