Radian Weapons AX556 ADAC Billet Stripped Lower Receiver

Machined from billet 7075-T6 aluminum, the AXTS 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. To hold the bolt back using the A-DAC, simply pull the charging handle to the rear, depress the right-side magazine release button, then release the charging handle. Other features and specifications include:

  • Billet machined 7075-T6 aluminum construction w/ integral trigger guard and flared magazine well
  • SART (Self-Adjusting Receiver Tensioner) spring-loaded plunger to reduce upper/lower wobble
  • Radian Talon 45/90 Ambidextrous Safety Selectors (long/short)
  • Enhanced Takedown Pin Set
  • All proprietary hardware included (extended bolt catch, left-side magazine release paddle, right-side magazine release button, right-side bolt release paddle, hammer pin)

This is a regulated item and requires shipment to a Federal Firearms License holder. After you have placed your order, please have your order number and a copy of your preferred store’s FFL emailed to info@rooftopdefense.com to avoid delays. After I have received their FFL, I will ship your order as soon as possible!

    This is by far my favorite lower I’ve ever built. This is my current duty rifle and it has not let me down. A truly ambi lower as well for all the lefties out there.
