Complete Your AR Build

Stripped and assembled upper receivers, barrels, and handguards for your rifle or pistol build.

Complete your AR platform build with our selection of upper receivers and components. Choose from stripped uppers for fully custom builds or complete assembled uppers for quick installation. Our inventory includes both mil-spec and enhanced designs featuring M4 feed ramps, forward assists, and ejection port doors.

Pair your upper with our selection of barrels in various lengths, calibers, and profiles, along with handguards ranging from classic drop-in styles to modern free-float M-LOK and KeyMod systems. Each component is sourced from reputable manufacturers and tested for proper fit and function with standard lower receivers.

Key Features:

  • Stripped and assembled upper receiver options
  • Barrel lengths from 7.5" to 20"
  • Multiple caliber options (5.56, .300BLK, 9mm, etc.)
  • Free-float and drop-in handguard systems
  • Complete upper kits with all necessary components

⚠️ Legal Note:
Upper receivers alone are generally not considered firearms under federal law. However, when paired with other components, they may create regulated items. Certain states have restrictions on barrel length, overall length, and specific features. Purchasers are responsible for ensuring their final configuration complies with all applicable laws, including NFA regulations for short-barreled rifles.
