Product Description

Machined from billet 7075-T6 aluminum, the AX556 is a fully ambidextrous lower receiver for AR15-style firearms. In addition to the Talon Ambidextrous Safety Selector, left-side magazine release, and right-side bolt release, the AX556 features the patented A-DAC (Ambidextrous Dual Action Catch), which allows right-handed shooters to easily lock the bolt to the rear without taking their hand off fire control.
