    It was easily machined and well machined except one hole . The buffer catch .. it wasn’t big enough I had to sand it down a little so the catch wouldn’t get stuck , I didn’t ask for a refund or help , because I knew it would take some time so I just fixed it my self , but over all good shit

Frequently Asked Questions for the AR-15 80% Polymer Lower Receiver With Jig:

1. What is an 80% lower receiver?
It’s a lower receiver blank that’s roughly 80% complete — the fire control group area, trigger and hammer pin holes, trigger slot, and safety selector hole still need to be machined before it becomes a functional AR-15 lower.

2. Does this require an FFL transfer?
No. Since it’s not yet a complete, functional receiver, it is not considered a firearm and does not require an FFL transfer — it ships straight to your door, except to the restricted states listed above.

3. What’s included in the kit?
The kit includes the polymer 80% lower receiver, the jig, drill bits, and the end mill needed to complete the machining.

4. What calibers is this compatible with?
It’s compatible with .223/5.56, 300 AAC Blackout, 9mm, 7.62×39, 6.5 Grendel, and .45 ACP builds.

5. What tools do I need to finish it?
Beyond the included jig, drill bits, and end mill, you’ll need a drill press or hand drill and basic shop tools to complete the machining.

6. Who makes this receiver?
It’s manufactured by Polymer80 and sold by Daytona Tactical.
