Modern defensive platforms demand controls that support speed, ergonomics, and left- or right-handed operation. For operators upgrading a rifle or building a versatile patrol or personal defense carbine, the lower receiver is the foundation for reliable, intuitive handling under stress.

Ambidextrous Controls and the A-DAC System
The standout feature is the patented A-DAC (Ambidextrous Dual Action Catch) which enables shooters to lock the bolt to the rear from either side of the rifle without repositioning the firing hand. Combined with fully ambidextrous controls and a Talon ambidextrous safety selector, this lower gives true bilateral control—an advantage for weak-hand transitions, awkward shooting positions, and fast malfunctions clearance drills.
Why the A-DAC matters
Traditional bolt catches and mag releases can force compromises in ergonomics. The A-DAC’s dual-action geometry reduces hand movement and keeps the shooter indexed on the fire control. For defensive applications where seconds matter, that design improves reload and manipulative speed.
