Complete Builds

Whether you’re looking for a fully assembled firearm or a matched parts package ready for your next project, the 80% Arms Complete Builds collection brings it all together in one place. This category features a curated mix of complete rifle builds, factory-assembled platforms like the MOD100, and builder-ready kits designed to simplify your path from box to range.

For customers who want a turnkey solution, our assembled options arrive professionally built and ready to run. For builders who still want hands-on involvement, our complete build kits provide carefully matched components that eliminate the usual compatibility guesswork.

Turnkey Options and Builder-Ready Kits

Not every shooter wants the same level of involvement, and that’s exactly why this category exists. Inside you’ll find:

  • Fully assembled firearms ready for transfer

  • Complete rifle configurations

  • MOD100 serialized pistol platforms

  • Matched AR build kits

  • Proven component combinations

Every option is selected with the same focus on reliability, fitment, and real-world performance that 80% Arms customers expect.

Built on Proven 80% Arms Standards

80% Arms built its reputation by supporting builders with precision-machined components and thoughtful design. Our complete builds carry that same mindset forward, whether you choose a factory-assembled platform or a kit for your next project.

We prioritize:

  • Quality component pairing

  • Consistent assembly standards

  • Modern, shooter-focused configurations

  • Clean fit and finish

The goal is simple: reduce friction, increase confidence, and deliver platforms that perform the way they should.
