Madbull SI Mega Fins KeyMod Handguard Rail 9"

Step up your build with the Madbull SI Mega Fins KeyMod Handguard Rail in 9", a premium upgrade designed for shooters who value precision, modularity, and minimal weight. Developed in collaboration with Strike Industries, this rail features a unique internal fin structure that aids in barrel heat dispersion, keeping your rifle cool during extended use. With a balance of lightweight engineering and tactical functionality, it's built to perform under pressure.

The Mega Fins 9" handguard incorporates a 7-sided (heptagonal) KeyMod system, providing flexible accessory placement across the entire handguard. Whether you’re mounting lights, lasers, or angled grips, this system ensures a secure fit exactly where you need it. The full-length 1913 Picatinny top rail supports optics and iron sights while maintaining a streamlined profile.
