The Aero Precision X15 AR15 Gen 2 stripped lower receiver is a precision-machined foundation for building a custom AR15 from the ground up. Machined to mil-spec dimensions from 7075-T6 forged aluminum and finished in hard-anodized black, this lower receiver is engineered to work seamlessly with standard AR15 upper receivers and components. Whether you're assembling your first rifle or your tenth, a quality stripped lower is where every build starts—and Aero Precision's Gen 2 design brings refinements that make the build process smoother and the final fit tighter.
The Gen 2 improvements address real pain points in AR15 assembly. The upper tension screw with a nylon tip lets you fine-tune the fit between upper and lower receiver, eliminating rattle and achieving a solid lockup with virtually any standard AR15 upper. The increased magwell flare isn't just functional—it makes magazine insertion faster and more intuitive, and it gives the lower a cleaner, more purposeful appearance. The rear takedown pin detent hole is threaded for a 4-40 set screw, giving you a reliable detent solution without workarounds.
At 8.35 ounces, this stripped lower is ready to accept your choice of fire control group, buffer tube, stock, and grip. It's marked "Cal Multi" to acknowledge the AR15 platform's versatility across calibers. This is a no-frills, no-compromise component designed for builders who understand that the lower receiver is the regulated foundation of your build and deserves to be as solid as everything else going into the gun.
| Platform | AR15 |
| Material | 7075-T6 forged aluminum |
| Finish | Hard-anodized black |
| Markings | Cal Multi |
| Weight | 8.35 oz |
| Receiver Type | Stripped (fire control group and buffer components not included) |
Yes. The Aero Precision Gen 2 lower is machined to mil-spec dimensions and is designed to work with any standard AR15 upper receiver. The Gen 2 upper tension screw lets you dial in the fit to eliminate rattle or excessive play.
A stripped lower is the machined receiver housing only—it does not include the fire control group, trigger, hammer, buffer tube, stock, or grip. You'll need to source and install these components separately to complete a functioning AR15. The lower is the foundation; everything else is your choice based on your intended use and preference.
The package includes the stripped lower receiver and the Gen 2 nylon-tipped upper tension set screw.
No. This is a stripped lower receiver. It comes without a fire control group, trigger, hammer, or springs. You will select and install your own trigger and FCG components.
