The A-DAC15 lower provides ambidextrous magazine and bolt controls, including the ADAC function that enables locking the bolt via the right-side mag-release. This layout supports efficient manipulation from either side while maintaining the AR-15 manual of arms.
Both upper and lower receivers are precision-machined from billet aluminum and include an integral trigger guard and a flared magwell. The uniform Flat Dark Earth Cerakote finish is applied to the receivers and handguard for a cohesive, durable exterior.
The 15.5 in free-float M-LOK handguard offers ample mounting space along its slots and a continuous top rail for uninterrupted alignment across the upper and handguard. The handguard is aluminum and ships with the barrel nut already installed, and a dedicated wrench is included.
This is a builder kit configured for custom component selection. It does not include a barrel, gas system, BCG, charging handle, stock/buffer assembly, sights, or optics. The lower is marked MULTICAL to accommodate multi-caliber AR-15 builds. Designed and manufactured in Oregon, USA. Mfg Part Number: R0406.
