Aero Precision X15 Gen 2 AR-15 Receiver Set, Flat Dark Earth Cerakote
This matched upper and lower receiver set from Aero Precision’s Gen 2 series gives builders a ready foundation for a quality AR-15. Forged from 7075-T6 aluminum and finished in factory-applied Flat Dark Earth Cerakote, the set combines mil-spec strength with modern ergonomic touches like a flared magazine well and pictograph selector markings. Multi-caliber markings add flexibility for future barrel choices, while the upper’s 14-slot flat-top rail makes optic mounting straightforward.

The Gen 2 lower features several practical upgrades over earlier X15 versions. A threaded rear takedown detent hole simplifies spring installation, while the receiver tensioning screw lets you fine-tune the fit between upper and lower.
Its flared magazine well speeds reloads and improves grip when handling the rifle by the magwell. Clear pictograph-only selector markings keep controls intuitive and uncluttered.
The upper receiver ships with M4 feed-ramp cuts, a forward-assist boss, shell deflector, and a continuous 14-slot Picatinny rail. These standard mil-spec features ensure broad compatibility with popular AR-15 components.
Both receivers wear a matching Flat Dark Earth Cerakote finish applied at the factory, offering uniform color and enhanced corrosion resistance. The multi-caliber marking gives builders the freedom to pair the set with a wide range of AR-15 cartridges.
