Overview The Premium 80% Lower Fire/Safe Marked – Billet is exactly what the name says: a billet 80 percent lower that comes with the selector markings already engraved. You get the raw material and the challenge of completing the fire control pocket and trigger pin holes yourself. Because it is a billet piece, you are looking at a tighter grain structure and a more uniform finish compared to forged options. It is a great way to build a custom rifle while keeping your project off the books until you finish it. Just remember: once you complete the machining, you are legally responsible for marking it per ATF guidelines. Features & Specs This blank is machined from 7075-T6 aluminum, the standard for durable AR receivers. The fire/safe markings are laser-engraved and will not wear off with normal handling. Here is what you get in the package: Billet 7075-T6 aluminum construction with a hardcoat anodized finish Pre-marked fire and safe selector engravings on both sides of the lower Compatible with standard AR-15 lower parts kits and takedown pins Every premium 80% lower fire/safe marked – billet we stock is inspected for machine finish and alignment before it ships. The trigger pocket is left slightly undersized so you can dial in the fitment yourself. The bolt catch channel is also pre-machined, saving you a step during finishing. Integral trigger guard design for added strength Flared magazine well for easier reloads during high-stress drills Accepts standard buffer tubes and pistol grip configurations Who It's For This part is for the builder who wants control over every tolerance in their rifle. If you have a drill press, a jig, and a few hours of patience, this premium 80% lower fire/safe marked – billet is your next project. It suits the DIY enthusiast who prefers to cut their own trigger pocket rather than rely on a factory spec. It also works well for the shooter who wants a dedicated lower for a specific caliber or barrel length without buying a whole new serialized receiver. Because it is an 80 percent blank, you can build multiple uppers and swap them onto this lower without worrying about registration numbers. We recommend this for anyone with basic metalworking experience. If you have completed one or two lowers before, this billet version will feel familiar but with a nicer finish out of the bag.
