Build Your Own AR-15 for Just $315

At Right To Bear, we believe that building your own AR-15 should be an option for everyone—not just dedicated enthusiasts. That's why we created the BN Complete AR-15 Rifle Build Kit, a cost-effective and high-quality solution that makes assembling a reliable AR-15 accessible and affordable. Whether you're a first-time builder or an experienced enthusiast, this budget-friendly AR-15 build kit provides everything needed to complete your rifle with minimal effort.

Unlike other build kits, these BN Complete AR-15 Kits feature a fully assembled upper receiver, eliminating the need for complex installations. Key components, including the barrel, gas system, bolt carrier group, charging handle, muzzle device, and handguard, are pre-installed and secured before shipping. All that's left is assembling the lower receiver, attaching the upper, and your rifle is complete.

Why Choose a BN Complete AR-15 Build Kit?

  • Budget-Friendly: A complete AR-15 build for just $315, offering a high-value option without compromising quality.
  • Easy Assembly: The upper receiver arrives fully assembled, requiring only basic tools to complete the lower receiver.
  • High-Quality Components: Designed for reliable function, durability, and smooth performance right out of the box.

Explore our selection of BN Complete AR-15 Rifle Build Kits and other affordable AR-15 parts to start your build today. With a fully assembled upper, mil-spec components, and a simple assembly process, these kits offer one of the best values in the AR-15 market.

A quick note on pricing: we've held this kit at $300 for as long as we could, but rising costs on key components have made that no longer sustainable. The small adjustment to $315 lets us keep using the same mil-spec parts and fully assembled upper you've come to expect, without cutting corners on quality.
