Keymod Aluminum Picatinny Rail Sections,4-Slot 5-Slot

Key Features

• Set of Two Lengths: Includes both 4-slot (short) and 5-slot (medium) rail sections. Use the 4-slot for compact lights and backup sights, the 5-slot for red dots and magnifiers — right-size your rail for each accessory.
• Aluminum Construction: Unlike polymer KeyMod rail sections that flex under load, these aluminum rails are rigid enough for optics that must hold zero. The 6061 aluminum body with hard anodizing withstands recoil and impact.
• KeyMod-Specific Lockup: The KeyMod lug geometry matches the KeyMod slot profile exactly — full engagement of the locking surface. The lug is steel, not aluminum, for maximum durability at the interface point.
• Beveled Edges: All edges are beveled and deburred — no sharp corners to cut hands, snag on gear, or abrade slings and cables.
• Recoil Lug: Integrated recoil lug prevents forward/backward shift under recoil. Once mounted and torqued, these rails don’t move — your accessory holds zero.
