The Blackout Defense AR-15 was designed from the ground up for stability and precision. At the heart of the rifle is the patented Blackout Defense lower receiver featuring our Presslock™ Technology, which consistently applies six pounds of back pressure on the upper to create a rigid base that is still easy to field strip. In addition, the receivers are machined from billet 7075-T6 aerospace-grade aluminum, which offers strength and rigidity over the more commonly used 6061 aluminum.
The match-grade barrel is machined from 416R stainless steel, which offers superior abrasive resistance over the more commonly used 4150 chrome-molly steel. All firearms are hard coat anodized and then finished with custom Cerakote paint to provide further corrosion resistance and to facilitate heat dissipation. With its innovative design and quality raw materials, the Blackout Defense Mark 1 Rifle will change the way you shoot.
The Quantum series lower receivers are equipped with our patented Presslock™ technology. The Linear Compression Pad ensures a tight, rattle free fitment, essentially "bedding" the upper and lower receiver together while eliminating carrier tilt.
Zero pre-travel. Zero post-travel. Combined with our short and positive reset design, the Zero trigger is exceptionally smooth, crisp, and fast.Learn more or Buy now
When you need to shoot flat, the Horizon™ compensator is virtually unmatched in functionality and versatility. The Horizon™ features four gas ports evenly distributed across the top at 25º increments. Ideal for when shooting in compromised or angled positions.Learn more or Buy now
We turn our 416R stainless steel barrel blanks into works of art. The blanks are gundrillud and reamed at slower speeds and lapped to remove all tooling marks. Our barrel profile features strategically placed linear expansion rings that control the heat growth of the barrel during heavy use. These unique design features, coupled with our adherence to improved machining tolerance standards, result in straighter bores, a superior finish, and improved accuracy.Learn more or Buy now
The Quantum Mark 1 features solid billet upper and lower receivers. Made from 7075-T6 aerospace-grade aluminum, they offer superior strength and rigidity. And since we’re machining from a solid block of aluminum, our tolerances are ensured and tediously inspected.
Radian's Raptor™ charging handle is made from aircraft grade 7075 aluminum and MIL-SPEC anodized. Its ambidextrous design allows for multiple ways of use, no matter your shooting side or position.
Our carrier is manufactured from 8620 steel, while our shot-peened bolt is made from either 9310 or carpenter 158. The bolts are batch high pressure tested and individually magnetic particle inspected after heat-treat to ensure no microcracks.Learn more or Buy now
