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)

The search is over! Radian’s lower receiver checks every box. Having complete ambidextrous controls pre-installed, saves time, money, and provides me with peace of mind, knowing it was done right. You truly cannot go wrong with this lower. Keep in mind, it does use a proprietary trigger pin, but honestly its a great design and works perfectly with a Geissele trigger. Amazing customer service from Sol, and shipping was fast. Rooftop has a customer for life!

Dude! Amazing quality. Looks awesome. The only downside I have at the moment is with the proprietary trigger pin. Just know, if you buy this, you will not be able to use a drop-in trigger. Then again, just spend the money on a Geissele and be done with it. This company ships fast. Just awesome.

Always heard Radian was a top tier lower and I have always wanted one. Finally pulled the trigger and all I can say is wow. The machining on this thing is top notch, love the ambi controls. And I didn’t even know about the tension screw for the upper/lower fit but it was a nice surprise. If you’re looking for a baller build this is your lower!

Great lower as I’ve been wanting one for awhile. When you think about how you get the talon and much of what you would need in an lpk it’s worth it to get this. Rooftop is gtg as I’ve always read about them on reddit and decided to run with it.

This lower is the great quality you’d expect from Radian and I’m excited to complete my build, but what I’m more impressed with, and what prompted me to leave a review is the service I received. I ordered this on a Sunday evening and I woke up Monday morning with a shipment update and tracking number. Can’t think of a time I’ve ever had something shipped so quickly, I’m not confident I’d have received equal service elsewhere.
