Considerations & Trade-offs

  • This is a stripped lower receiver, so it is only the starting point for a custom AR-15 build and does not include the components needed for a complete lower assembly.
  • The upper tension screw is intended to fine-tune fit with a standard AR-15 upper, but final receiver fit still depends on the parts used in the build.
  • It is specified for small pin .154" hammer/pin holes and .250" pivot/takedown pin holes, so compatibility should be checked against the intended parts before purchase.
  • FFL required for purchase, which adds transfer and paperwork considerations not present with non-regulated accessories.
