The A-DAC 15 sets a new standard in AR-15-style lower receivers, machined from billet 7075-T6 aluminum for uncompromising durability and performance. Designed with full ambidexterity in mind, it integrates essential features like the Talon ambidextrous safety selector, a left-side magazine release and a right-side bolt release. A standout feature of the A-DAC 15 is its patented A-DAC (Ambidextrous dual-action Catch), engineered to enable effortless bolt locking for right-handed shooters without adjusting their grip. To engage the bolt hold-open using the A-DAC, simply pull the charging handle rearward, depress the right-side magazine release button and release the charging handle to secure the bolt to the rear position. This innovative design enhances operational efficiency and user convenience, ensuring smooth and intuitive handling in any shooting scenario.
