Madbull SI Mega Fins KeyMod Airsoft Rifle Handguard Rail 9" – Tactical Black
The Madbull SI Mega Fins 9" KeyMod Handguard in Tactical Black is a sleek, performance-enhancing upgrade for AR-15/M4 airsoft rifle builds. Designed through a collaboration between Strike Industries and Madbull, this handguard combines cutting-edge engineering with battle-ready durability. Its 7-sided KeyMod layout allows maximum flexibility for mounting foregrips, lights, lasers, and other gun accessories, giving you complete control over your setup.
Featuring the unique “Mega Fins” internal cooling system, this rail helps disperse heat more efficiently, promoting better handling and consistency during sustained firing. The full-length Picatinny top rail provides a rock-solid platform for sights and optics, while its slim, ergonomic profile keeps your rifle lightweight and agile. With a tough matte finish and high-strength alloy construction, the 9" Mega Fins rail is ideal for players looking to boost precision and handling without adding bulk to their airsoft gun.
