About this product
Build it yourself: the Premium 80% Lower Fire/Safe Marked – Billet is on the shelf in Houston and ready to ship across Texas and beyond.
Last reviewed: 2026-04-30 by Prince Frederick , FFL08 holder · Forward Freedom LLC · Prince Frederick, MD — AR-platform PMF specialist. This is an unfinished AR-15 80% lower receiver in 7075-T6 billet aluminum, fire/safe-marked and ready for completion. Sold as a non-firearm component for personal manufacture under federal law — the receiver is not a firearm until the builder completes the trigger pocket.
An 80% AR-15 lower has the fire-control pocket left solid; finishing it takes a router or drill press, a jig and an afternoon.
Shipped fast and discreet from Texas Gun Shops in Houston, TX. Unfinished frames and receivers cannot ship to states or cities that prohibit them. Not sure about your area? Message us before you order.

Frequently asked questions
- Do I need an FFL to buy the Premium 80% Lower Fire/Safe Marked – Billet?
- No FFL is required for an unfinished 80% frame or receiver under federal law, because it is not yet a firearm. Some states and cities restrict or ban unserialized frames, and we cannot ship there. Check your local law before ordering. This is general information, not legal advice.
- Are Polymer80 frames legal in Texas?
- Texas has no state law restricting 80% frames or receivers for personal builds. Federal rules still apply, and a home-built firearm cannot be sold without proper licensing. Laws change, so confirm the current rule before you build.
- What do I need to finish the Premium 80% Lower Fire/Safe Marked – Billet?
- The matching jig kit, the included drill bits and end mill, and a drill press or a router. Each product page names the frame family it fits. Email us your model if you are unsure and we will confirm before you pay.
- Is this in stock and how fast does it ship?
- Yes. It ships from Houston, TX within one to two business days, tracked and in plain packaging.
