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.

    Just received mine today. Love the Ambi controls being left-handed!Customer service & shipping was great! Couldn’t be more happy with the overall experience

  2. Trevon (verified owner)

    100% satisfied with this lower. Yes it is expensive but you are getting a top end receiver. The ambi controls are great. The finish and look of the receiver is amazing. Paired great with a BCM MK2.
