Aerondight 18-Inch .22 ARC AR-15 Full Build Kit

The Aerondight is a complete .22 ARC build kit designed for precision shooters who want a dedicated platform for long-range target work. This kit pairs an 18-inch 416R stainless steel barrel with a freefloat M-LOK handguard, a 6.5 Grendel II bolt carrier group, and a full mil-spec lower parts kit. Everything needed to complete a functional rifle is included except the serialized lower receiver.

Perfect For

• Precision shooters building a dedicated .22 ARC platform
• Long-range target shooters seeking inherent accuracy
• Builders who want a complete kit minus the lower receiver
• Shooters interested in exploring intermediate cartridge performance

Precision-Focused Design

The 18-inch barrel length and 1:7 twist rate create a balanced platform optimized for .22 ARC ballistics. The 416R stainless steel construction resists corrosion and maintains consistency across extended shooting sessions. The rifle-length gas system paired with the micro low-profile gas block cycles reliably while keeping the upper receiver profile clean.

Freefloat Accuracy Foundation

The 15-inch M-LOK handguard floats free from the barrel, eliminating contact that can introduce harmonic inconsistencies. The partial Picatinny top rail section accommodates optics and accessories without forcing full-length rail commitment. M-LOK mounting points distribute accessories without adding unnecessary weight forward.

Bolt Carrier Group Compatibility Note

This kit uses a 6.5 Grendel II bolt carrier group based on the Grendel bolt pattern, which functions reliably in the .22 ARC chamber. The QPQ nitride finish provides corrosion resistance and smooth cycling characteristics.

Complete Lower Assembly Included

The kit includes a complete mil-spec lower parts kit, 6-position buffer tube, standard carbine buffer, carbine recoil spring, castle nut, end plate, and Ranger A-Frame stock. All components are mil-spec compatible and ready for assembly into a stripped lower receiver. The lower receiver itself is not included.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
