Troy Industries Troy Rail Section Alpha Qars 4.2"

The Troy Industries Troy Rail Section Alpha QARS 4.2" is a quick-attach rail segment designed to expand accessory mounting capability on Troy rail systems. This 4.2-inch section secures directly to Troy Alpha, Delta, and TRX rail platforms using a two-screw fastening system, enabling operators to position tactical accessories—lights, lasers, grips, and backup sights—at precise locations along the rail without permanent modification. The modular approach gives shooters flexibility to reconfigure loadouts for different operational requirements or training scenarios.

At 0.09 pounds and 6.25 inches in length, the rail section adds minimal weight while providing substantial mounting real estate. The two-screw attachment design distributes load evenly across the rail's backer surface, preventing rotation or shift during recoil or weapon manipulation. Troy's rail sections are finished in durable black anodizing, standard for mil-spec rail platforms, and integrate seamlessly with Troy's ecosystem of accessories and other QD (quick-detach) components.

This rail section serves precision shooters, tactical rifle builders, and law enforcement personnel who run Troy rail systems on service rifles, patrol carbines, or precision platforms. It's particularly valuable for users who need to add mid-rail accessory space without replacing the entire rail assembly or relying on offset mounts. The 4.2-inch length provides enough real estate for compact accessories while maintaining sight picture integrity. Compatible with Troy Alpha Delta, TRX 308, TRX Extreme, HK rails, T-22 Sport Chassis, M7 Uppers, and M7 Kit platforms.
