Bear Creek Arsenal LR-15 Features The Bear Creek Arsenal LR-15 is forged from 7075 aluminum and fully machined to mil-spec tolerances with an anodized black finish delivering a stripped lower receiver at 1 lb that provides a solid and properly dimensioned foundation for AR-15 builds across multiple caliber configurations. The 7075 aluminum forgings provide the material strength and dimensional consistency required for a mil-spec AR-15 lower receiver that accepts standard AR-15 components without fitment issues. Anodized black finish provides corrosion resistance and surface hardness appropriate for a receiver that will see repeated component installation and removal across the build process and service life. The Multi-Caliber stamp identifies the LR-15 as a platform-agnostic stripped lower compatible with the full range of AR-15 upper receiver and caliber configurations that use the standard mil-spec lower interface. Fully machined fire control group pockets magazine well and takedown pin holes ensure proper component fitment and function without requiring additional machining or fitting. Bear Creek Arsenal designed the LR-15 as a straightforward mil-spec stripped lower for builders who want a reliable properly toleranced foundation without unnecessary cost premium.
