Technical Specifications and Build Considerations

This receiver set is optimized for 9mm Luger cartridges, providing a stable platform for pistol-caliber builds. The billet design includes reinforced areas around critical stress points, such as the buffer tube threads and takedown pins, to prevent cracking under recoil. When paired with a compatible AR-9 barrel and bolt carrier group, it delivers smooth cycling and consistent accuracy. We recommend using quality components to maximize performance and ensure safety.

FAQ: Why Choose This Product?

• Is this set legal to purchase? Yes, the 80% lower is unserialized and can be shipped directly to most states without an FFL, but always check local laws before completing it.
• What tools are needed to finish the lower? You’ll need a drill press or milling machine, along with a jig and appropriate bits, which are often sold separately.
• Can I use other magazines besides Glock? This set is specifically designed for Glock magazines; using other types may require modifications and could affect reliability.
• Is the upper receiver complete? The upper is typically stripped, meaning you’ll need to add a barrel, handguard, and other components to complete your upper assembly.
