Vector Optics KeyMod 4" Picatinny Rail Section (SCRAAM-23) — Lightweight, rock-solid 1913 segment for lights, lasers, grips & bipods
The Vector Optics KeyMod 4 Inch Picatinny Rail Section adds a precision-machined 1913 Picatinny interface anywhere on a KeyMod handguard. Built from durable aluminum alloy with a low-glare matte finish, this 4″ rail gives you the fore-aft adjustment you need to place weapon lights, laser modules, vertical or angled grips, bipods, and sling accessories exactly where your ergonomics and balance demand. It’s supplied with tools for quick installation and is rated for real-recoil firearms, not just trainers or airsoft.
Main Advantages

- Optimized 4″ length: Ample slot run for positioning switches and mounts while keeping weight and bulk to a minimum.
- All-metal construction: Aluminum alloy body with a durable matte-black finish stands up to duty and range abuse.
- Real-world ready: Designed for live-fire calibers; perfect for AR-15/PCC builds, carbines, and lightweight hunting setups.
Use Cases & Setup Ideas
Lights & lasers
Mount a 1913-base light or laser at the ideal clock position for your grip—keep tape switches clear of sling hardware and front sights while maintaining a natural thumb reach.
Stability & control
Add a vertical/angled grip or a compact bipod where it best balances the rifle for barricade, prone, or off-hand stages.
Modular layouts
Keep the handguard slick. Bolt this 4″ segment only where you need accessory space, then remove it when you’re chasing ounces.
