What You Need to Know

A stripped lower receiver is the foundation of your custom rifle build. This is where you'll install your trigger group, safety selector, and buffer tube assembly. Franklin Armory's design accommodates both standard and binary trigger options, giving you flexibility in how you configure your rifle.

Whether you're building your first rifle or adding to your collection, this lower provides a solid platform for a reliable, accurate firearm. The forged construction resists wear and maintains dimensional stability through years of use.

Next Steps

You'll need to source the remaining components: upper receiver, barrel, bolt carrier group, handguard, stock, and fire control group. Many builders appreciate the control that comes with selecting each component individually.
