Battle Arms Development Workhorse Foundation
The Battle Arms Development Workhorse lower receiver provides a premium foundation for your AR-15 rifle build. Forged from 7075-T6 aircraft-grade aluminum, this lower delivers superior strength-to-weight ratio compared to 6061 aluminum while maintaining mil-spec dimensions and compatibility. The Type III hard anodizing process creates an extremely durable Flat Dark Earth finish that resists wear, corrosion, and environmental exposure. The M16-cut trigger pocket accommodates both standard AR-15 triggers and drop-in trigger cassettes without fitment restrictions, giving you maximum flexibility in fire control group selection.
Blem Value Without Performance Compromise
Blemished lowers feature minor cosmetic imperfections such as machining marks, anodizing inconsistencies, or surface irregularities that don't meet Battle Arms Development's first-quality standards. These cosmetic issues have zero impact on functionality, strength, or reliability—the lower performs identically to non-blem versions. For builders focused on performance rather than show-gun aesthetics, blem lowers represent exceptional value, delivering Battle Arms quality at a fraction of the cost. The FDE finish provides a distinctive appearance that coordinates with earth-tone builds and tactical accessories.
Gauntlet Arms Special Operations Stock
The Gauntlet Arms Special Operations stock features glass-filled polymer construction for enhanced durability and impact resistance compared to standard polymer stocks. The adjustable design allows length of pull customization across six positions to accommodate different shooter sizes, clothing layers, and shooting positions. The rubberized butt pad provides enhanced comfort during recoil and improved shoulder purchase for consistent cheek weld. Multiple sling mounting options including QD socket and traditional sling loop provide versatility for single-point, two-point, and traditional sling configurations.
Complete Lower Parts Kit with Fire Control Group
This kit includes a complete mil-spec lower parts kit containing all necessary components for lower receiver assembly: trigger, hammer, disconnector, springs, pins, selector, magazine catch, bolt catch, takedown pins, pistol grip, and all small parts. The included fire control group provides immediate functionality without requiring separate trigger purchase. Mil-spec dimensions ensure compatibility with aftermarket triggers and upgrades should you choose to upgrade later. Having all lower parts included eliminates the need to source individual components separately and ensures you have everything needed for a functional lower assembly.
Heavy-Duty Mil-Spec Buffer System
The heavy-duty mil-spec 6-position buffer tube provides robust construction to withstand the stresses of rifle operation and stock adjustment. The mil-spec diameter ensures compatibility with mil-spec stocks including the included Gauntlet Arms stock. The tube provides the mounting platform for the adjustable stock and houses the buffer and spring assembly. The standard carbine buffer and spring provide the recoil management system necessary for reliable cycling. This complete buffer system pairs with the included lower parts kit and upper assembly to create a functional AR-15 rifle.
Multi-Caliber Build Versatility
The Battle Arms Development Workhorse lower is designed to accommodate various AR-15 platform calibers beyond standard 5.56 NATO. This multi-caliber compatibility allows you to build rifles in .223 Wylde, .300 Blackout, and other AR-15 compatible chamberings by pairing with appropriate upper assemblies and magazines. The lower's design ensures proper magazine well dimensions and component fitment across caliber options.
FFL transfer required for lower receiver purchase. Follow all applicable federal, state, and local laws regarding rifle configurations. Rifles require minimum 16-inch barrels or compliance with applicable laws. Always follow safe handling practices and manufacturer guidelines. Ensure proper fit and function testing after assembly.
