An 80% lower receiver jig is the fixture used to guide the drill bits and end mills needed to machine the fire control pocket, trigger slot, and selector and trigger/hammer pin holes in an 80% AR-15 or AR-9 lower receiver blank. Without a jig, accurately locating and drilling these holes to the correct depth and position requires machining expertise and precision tooling. The jig clamps to the 80% lower receiver blank and uses drill guides and depth stops to ensure each operation is performed at the correct location, angle, and depth for the completed lower to accept standard mil-spec fire control group components. The Stealth Arms jig is compatible with standard AR-15 and AR-9 80% lower receiver blanks that use the standard mil-spec lower receiver dimensions — confirm the jig is compatible with your specific 80% lower receiver brand and model before ordering, as some 80% lowers have proprietary dimensions that require a matching proprietary jig. Completing an 80% lower receiver requires a drill press or milling machine, appropriate drill bits and end mills, cutting lubricant, and basic machining skills. The jig does not eliminate the need for proper tooling — it provides the precision guides to use that tooling correctly. All applicable federal, state, and local laws governing the manufacture of unserialized firearms apply — verify compliance in your jurisdiction before purchasing and using this product.

Frequently Asked Questions

Is this jig compatible with all 80% lower receivers?

The Stealth Arms jig is designed for standard mil-spec AR-15 and AR-9 80% lower receiver blanks. Some 80% lower receivers have proprietary dimensions that require a matching proprietary jig — confirm your specific 80% lower receiver is compatible with the Stealth Arms jig before ordering.

What tools are required to use this jig?

Completing an 80% lower receiver requires a drill press or milling machine, appropriate drill bits and end mills (often included with the 80% lower receiver or available separately), cutting lubricant, and basic machining knowledge. The jig provides precision guides for the operations but does not replace the need for proper power tooling.

Is building an 80% lower receiver legal?

Federal law permits individuals to manufacture firearms for personal use in most circumstances, but state and local laws vary significantly. Some states prohibit or restrict unserialized firearms entirely. You are responsible for knowing and complying with all applicable federal, state, and local laws before purchasing and using this product.
