The 2A Armament Aethon Receiver Set incorporates a new aesthetic and a different feature set to their standard Balios Lite Gen 2 receivers. The lower incorporates a refreshed magazine well design, as well as a new grooved beaver tail area. Dual QD swivel sockets have been integrated at the rear of the receiver, ideal for use with your favorite single-point slings. Like the Balios Gen 2, the Aethon uses a screw-in pin to retain the bolt catch/release, removing one of the biggest headaches when assembling a lower as well as significantly reducing the chances of slipping and scratching the receiver.

Aethon Lower Features
  • Weighs just 6.8 oz stripped.
  • CNC machined from American sourced 7075-T6 plate aluminum.
  • Integrated lightweight winterized trigger guard for gloved use.
  • Integrated QD mounts.
  • Threaded bolt catch retaining pin (included).
  • Flared magazine well.
  • Set screw captive detent spring installation.
  • Rear tensioning screw to eliminate all wobble.
  • Durable Type III, Class 2 hardcoat anodized finish.

  • Weighs just 6.9 oz stripped
  • CNC machined from American sourced 7075-T6 plate aluminum.
  • Ready for your favorite forward assist.
  • Durable Type III, Class 2 hardcoat anodized finish.

Despite their differences, 2A Armament has designed the Aethon receivers to be a perfect aesthetic match to the Balios Gen 2, allowing shooters to pick and choose the feature set that best suits them. As with all 2A Armament products, the Aethon is built around top-quality craftsmanship and weight savings.
