Also Included with the American Defense UIC lower receiver is the dimpled takedown pins that make disassembling your rifle easier. To eliminate any possible wobble between receivers, a tension screw is included. This screw is installed in the bottom of the lower near the grip screw and applies pressure on the upper receiver. American Defense have included every possible feature in this stripped lower receiver group, so you can build a highly capable AR-15.

Ratings & Reviews
The Best Ambi AR Lower on the Planet
This is the finest AR15 lower on the market today, bar none. I run this lower on all my AR builds. The ambidextrous setup is better than the LWRC ambi lower, even. Manufacture, fit and finish are flawless. The magwell has a nice flare that doesn't present itself on the outside profile. The left-side bolt catch is large and ergonomic. The ambi left side mag release is perfectly placed. Most significant, the right side lever serves to both release and catch the bolt carrier. Intuitive operation, for both right and left-hand operation. Right handers can lock the BCG to the rear without removing their firing hand from the pistol grip! If you are looking for a superior ambidextrous AR lower, look no further. The ADM UIC is by far the best.
I bought a Radian AX556 and an ADM UIC/MP4. Kept the ADM
The Radian is beautiful, and really nice to handle. No doubt, the machining is just a notch above ADM. But you know what?
<br>The ADM works with Maxim's SCW pistol braces, while the A-DAC button prevents the support bars on the brace from fully retracting.
<br>Also, having had some time to use the Radian, ADM and a POF (all of which have the bolt catch/release feature), the ADM is easily the most intuitive (up to catch, down to release) and natural (a sweeping motion up/down with my trigger finger) than press/hold and press like the AX556 or the quasi-uncomfortable button POF inserted into the trigger guard.
<br>I like the simplicity, intuitiveness, and restraint of the ADM. Couldn't recommend it more highly.
