US PALM STORM AR15 STRIPPED LOWER RECEIVER

Building a quality AR-15 starts with a solid foundation. The US PALM Storm stripped lower receiver delivers mil-spec tolerances and 7075-T6 aluminum construction in a multi-caliber-capable package, giving builders the flexibility to configure their platform for a wide range of uses.

The US PALM Storm is a stripped AR-15 lower receiver designed for multi-caliber compatibility, machined from 7075-T6 aluminum with a Type III hardcoat anodize finish.

The multi-caliber design expands your build options considerably, making this lower compatible with upper assemblies chambered in everything from 5.56 NATO to pistol-caliber conversions. The Type III hardcoat anodize delivers a hard, wear-resistant surface that holds up to sustained range use and rough field handling. California Roster certification makes this receiver a viable option for builders in restricted states where many AR lowers cannot be sold. Available exclusively through Lipsey’s, the Storm represents a curated, quality-verified component for dealers and builders who want confidence in their parts sourcing.

Compatible with standard mil-spec AR-15 lower parts kits, trigger groups, and controls from most major manufacturers across a wide range of caliber configurations.
