Workhorse 15" Rail .750 Gblock Combo

The Workhorse 15" Rail .750 Gblock Combo is a complete handguard and gas block system engineered for AR-15 platform builders and tactical shooters who demand modularity without compromise. This combo addresses a critical workflow challenge: integrating a precision gas block with a modern rail system in a single package, eliminating the need for separate sourcing and compatibility guesswork. Built for law enforcement, military, and civilian operators running intermediate to long-distance defensive or duty carbines, the Workhorse combo accelerates build times while maintaining professional-grade component quality.

The 15-inch M-LOK handguard provides ample real estate for mounting tactical accessories—lights, lasers, foregrips, and optic risers—while keeping profile compact for vehicle operations and tight-quarters work. The .750-diameter gas block is precision-fitted to standard AR-15 barrels, delivering reliable gas port alignment critical for consistent cycling and reliability. Anodized black finish offers corrosion resistance and a professional appearance suited to duty and training environments. The one-pound weight distribution keeps the rifle balanced and reduces shooter fatigue during extended operations, a detail that matters in multi-day training or deployment scenarios.

This combo fits all standard AR-15 receivers and upper assemblies, making it ideal for custom builds, rifle upgrades, or duty weapon modernization. The M-LOK slots are industry-standard, ensuring compatibility with thousands of aftermarket accessories without proprietary adapters. Installation requires basic armorer knowledge—proper barrel seating and gas block pinning—but the integrated design eliminates fitment errors common when sourcing components separately. Professional gunsmiths and experienced builders will appreciate the time savings and confidence that comes from a matched system.
