This is what 2A Armament says :



2A-Armament is proud to introduce the Aethon billet upper and lower receiver for 2017.  With all the same craftsmanship and weight savings that are trademark 2A-Armament qualities the Aethon receiver set offers a different feature set than our flagship Balios Lite Gen 2 receivers.  The Aethon lower incorporates a refreshed design on the mag well, a ergonomically designed ridged tactile grip, and integrated QD's into the receiver which provide good balance for a single point sling without having to "wrap one way or another" around the receiver extension.  Standard items for 2A Armament receivers are also included: a flared mag well, threaded bolt catch pin, set screw captive detent springs and a rear tensioning screw which guarantees a tight fit if running a third party upper.  Best of all, the Aethon and Balios Lite receiver sets are designed to aesthetically match each other perfectly to allow our customers to pick and choose the features they desire.
