Why Build Your Own AR-15 or AR-10 from an 80% Lower?
Building your own firearm starts with the receiver. By choosing an 80% lower receiver from Tactical Machining, you gain several distinct advantages over buying a serialized firearm:
- Privacy: Because an 80% lower is not considered a firearm by the ATF, it does not require a background check or FFL transfer to purchase. It ships directly to your door.
- Cost Savings: When you finish the receiver yourself, you avoid the "brand tax" and Federal Excise Tax (FET) associated with complete firearms, putting more of your budget into high-quality barrels and optics.
- Education: Milling your receiver with an 80 lower jig gives you an intimate understanding of how your rifle functions, making you a better owner and operator.
- Customization: You control the final finish and fitment. We offer Raw 7075-T6 aluminum options ready for custom coating, as well as Anodized receivers for immediate assembly across our AR-15 and AR-10 platforms.
Note: While federal law allows the home manufacture of firearms for personal use, state laws vary. Always verify your local regulations before ordering.
