There's something satisfying about starting a build from scratch, and that's exactly what this lower gives you. The Andro Corp ACI-15 is a stripped lower receiver, meaning it's just the bare forged aluminum shell with no trigger group, grip, or buffer hardware installed. That's the whole point. It hands you a blank slate so you can pick every single part that goes into your rifle instead of settling for whatever came pre-installed.
This receiver is forged from 7075-T6 aluminum, which is the same grade most reputable AR builders lean on for strength and long-term durability. It's cut to mil-spec dimensions, so your standard lower parts kit, buffer tube, and pistol grip are all going to drop right in without any fitting drama. Andro Corp has historically had these machined by A.O. Precision in Daytona, a shop with a long track record cutting receivers for other well-known AR manufacturers, so the tolerances are tight and consistent from unit to unit.
The black finish is a Type III hard coat anodize done to MIL-A-8625F, Class 2 spec, which is the same coating process used on military hardware because it holds up to scratches, sweat, and years of handling without flaking or fading. This particular lower carries multi-caliber markings, which just means it's cut and stamped in a way that supports builds in 5.56 NATO, 300 Blackout, 9mm, and 7.62×39, giving you room to change direction on a future build without needing a whole new receiver. It's a right-handed, standard configuration lower, so your controls go where you'd expect them.
Keep in mind this is a serialized firearm component, which means it has to ship to and be picked up from a licensed FFL, same as any other AR-15 receiver. Once it's in your hands, the rest is up to you. Drop in whatever lower parts kit, stock or brace, and buffer system fits your plans, and you've got the foundation of a rifle built the way you actually wanted it instead of the way it came in a box. Andro Corp backs this receiver with their lifetime warranty, so if something ever turns out off with the aluminum itself, they stand behind it directly as the manufacturer.
You're getting just the bare forged lower receiver itself, nothing else installed inside it. There's no trigger group, no grip, no buffer tube, and no magazine included. That's what makes it stripped, and it's meant to be paired with whatever lower parts kit and furniture you pick out.
This lower carries multi-caliber markings, which means it's set up to support builds in 5.56 NATO, .300 Blackout, 9mm, and 7.62×39, among others. The exact parts you'll need in your lower parts kit and magazine can shift depending on which caliber direction you go. It gives you flexibility if you're not locked into one build plan yet.
Yes, it's cut to mil-spec dimensions so it should mate up cleanly with any standard AR-15 upper receiver and accept typical lower parts kits, buffer tubes, and stocks or braces. It's forged from 7075-T6 aluminum, which is the go-to material for reliable, long-lasting builds.
Yes, this stripped lower is a serialized firearm component, so it has to ship to a licensed FFL for transfer just like any complete rifle would. Once it arrives at your dealer, you'll handle the paperwork there and take it home ready to start your build.
