FAQ

What tools do I need to complete this 80% lower?

You will need a drill press or a sturdy handheld drill, an AR-15 80% lower jig (sold separately), appropriate drill bits and end mills, and basic workshop safety equipment. A router with a jig is also a common method.

Does this work with Colt-style or other 9mm magazines?

No. This specific lower receiver is designed exclusively for the Glock-style magazine pattern, including Glock OEM, ETS, Magpul GL9, and similar magazines. It will not function with Colt-style, SIG, or other 9mm magazine types.

What parts kit do I need for this AR9 lower?

You will need a standard Mil-Spec AR-15 lower parts kit (LPK). However, you must also source a dedicated 9mm buffer, buffer spring, and either a 9mm-specific bolt catch or an adapter for reliable last-round bolt hold-open, as these often differ from standard .223/5.56 components.
