Radian A-DAC 15 Complete Rifle Lower Superb Ambidextrous AR-15 Lower, Black

Description

The Radian A-DAC 15 Complete Rifle Lower is Radian Weapons’ fully ambidextrous AR-15 lower, machined from billet 7075-T6 aluminum with an integral trigger guard and flared magazine well and finished in Radian Black Cerakote. This complete rifle lower comes assembled with a Radian Vertex FBX trigger, Magpul K2 grip, and a Magpul collapsible stock, ready to accept an AR-15 rifle upper. Out of the box the Radian A-DAC 15 Complete Rifle Lower needs only an upper to run.

What the A-DAC actually does

A-DAC stands for Ambidextrous Dual-Action Catch, and it solves the one control a standard AR-15 lower leaves on the wrong side for right-handed shooters. To lock the bolt back, pull the charging handle, press the right-side magazine release button, and let the charging handle go. Your firing hand never leaves the grip. The same lower also has a right-side bolt release paddle and a left-side magazine release paddle, so lefties get a true ambidextrous AR-15 lower and righties get faster reloads and malfunction clearing.

The Radian Talon safety selector can be set up for a short 45-degree or standard 90-degree throw, with long and short levers included. A spring-loaded SART plunger (Self-Adjusting Receiver Tensioner) takes up slack between upper and lower, which removes the wobble many AR owners otherwise fix with an accu-wedge. Enhanced takedown pins round out the package.

Building a rifle on this lower

Because it ships with a stock, the Radian A-DAC 15 Complete Rifle Lower is meant for rifle uppers with barrels of 16 inches or longer, or 14.5 inches with a pinned-and-welded muzzle device. Radian 14.5, 16, and 18-inch uppers pair naturally with it, and so does almost any mil-spec AR-15 upper you already own, which makes it the simplest way to put the A-DAC lower receiver and Radian controls on an existing rifle.

Never pair the Radian A-DAC 15 Complete Rifle Lower with an upper under 16 inches unless the rifle is legally registered as a short-barreled rifle; assembling one without ATF approval is a federal felony, and MAG5 does not sell NFA items. The Vertex FBX trigger uses a flat-faced blade that many shooters find gives more consistent finger placement than a curved trigger.

Pairing it with an upper

The Radian A-DAC 15 Complete Rifle Lower accepts standard mil-spec AR-15 upper receivers in 5.56, .223 Wylde, 300 Blackout, and other AR-15 calibers. For the closest color match, pair it with a Radian upper in the same Cerakote color, though parts coated in separate batches can vary slightly in shade. We stock several Radian uppers and upper and handguard sets, which makes it possible to build a Model 1 equivalent one piece at a time. If you plan to run 6mm ARC or 300 Blackout on the Radian A-DAC 15 Complete Rifle Lower, use magazines designed for that cartridge.

Honest trade-offs before you buy

This is a premium lower, and a mil-spec forged lower with a basic parts kit costs a fraction as much. Part of what you pay for is proprietary: the A-DAC bolt catch, paddles, and magazine release are Radian parts, so replacements come from Radian rather than any gun counter, though Radian does sell them individually. Some aftermarket ambidextrous magazine releases and bolt catches will not fit.

A lower receiver is the serialized part of an AR-15, so it is a firearm under federal law. You must be 21 or older to buy one from a dealer, and it transfers through an FFL with a background check. Some states restrict what you can build on it, including magazine capacity and features. Lower receivers can only transfer to residents through an FFL in their home state, so out-of-state buyers of the Radian A-DAC 15 Complete Rifle Lower will need it shipped to a local dealer.

Who the Radian A-DAC 15 Complete Rifle Lower suits

The Radian A-DAC 15 Complete Rifle Lower makes sense for AR-15 owners who want an AR-15 complete lower with Radian ambidextrous controls and trigger to drop onto an existing upper, and builders assembling a Model 1-style rifle one piece at a time. It is less compelling if you want the cheapest possible build or if you run a heavily customized parts kit you do not want to give up.
