Radian Weapons Model 1 ADAC-15 .300 BLK 9″ Pistol

The Radian Weapons ADAC-15 BLK pistol, catalogued as the Model 1 in .300 Blackout with a 9 inch barrel, is what happens when a parts company builds the complete rifle it always wanted to sell. Every Model 1 is assembled by hand, one at a time, by a trained gunsmith who inspects, test fires and cleans the weapon to guarantee it meets the most rigid quality standards.

This is not a parts bin build with a logo on it. It is Radian’s own component list, assembled the way they intended.

What the Radian Weapons ADAC-15 BLK Package Includes

The Model 1 features fully ambidextrous controls, adding much needed utility for both left and right handed shooters. That starts with the Radian Raptor-SD suppressor optimized ambidextrous charging handle and the Radian Talon modular ambidextrous 45/90 safety selector, two upgrades that owners of other rifles buy separately and install themselves.

The trigger is an ATC AR Gold match grade unit, and the rifle runs a 6 position mil-spec receiver extension with a QD end plate and an H2 carbine buffer. In .300 Blackout with a 9 inch barrel, this is a short, handy platform built around the cartridge that was designed specifically for exactly this configuration. From Radian Weapons, the attention to detail is the point.

Features and Build Quality

The specification list reads like a wish list because that is essentially what it is.

• Fully ambidextrous controls for left and right handed shooters.
• Upper receiver, lower receiver and handguard Cerakoted together for a perfect color match.
• Extended aluminum handguard with the Magpul M-LOK modular mounting system.
• Integrated upper and handguard stainless steel anti rotation pin for a solid interface.
• Radian Raptor-SD suppressor optimized ambidextrous charging handle.
• ATC AR Gold match grade trigger with an H2 carbine buffer and QD end plate.

Why the Details Matter

Cerakoting the upper, lower and handguard together is a small thing that tells you a great deal. Coating parts as a set is slower and more expensive, and it is the only way to guarantee they actually match rather than being three slightly different shades of the same color.

The Raptor-SD charging handle is worth calling out on a Radian Weapons ADAC-15 BLK pistol specifically. Suppressor optimized handles vent gas away from the shooter’s face, and since .300 Blackout in a short barrel is a cartridge that begs to be suppressed, that feature is being used rather than just listed. The H2 buffer likewise reflects a build tuned for the pressures of a short gas system.

Shooting, Ammunition and Care

.300 Blackout is a dual personality cartridge. Supersonic loads give you full power performance from a very short barrel, while subsonic loads paired with a suppressor are remarkably quiet. Both cycle well in a properly tuned rifle, and this one is set up with that in mind.

Keep magazines clearly marked. Because .300 Blackout uses the same magazines as 5.56, mixing ammunition in a range bag is the one genuine hazard the cartridge presents. Label your magazines and your ammunition cans and never let the two systems share a bag loose.

The M-LOK handguard gives you room to set the gun up the way you shoot it. A light, a hand stop and a sling mount all attach directly, and the extended length on the Radian Weapons ADAC-15 BLK means your support hand can reach well forward for control on a short, light pistol that wants to be driven.

Maintenance follows normal AR practice, with extra attention to carbon in the bolt carrier group if you shoot suppressed. Clean the chamber, lubricate the carrier rails and cam pin, and inspect the buffer and spring periodically. Explore our firearms collection for the rest of the lineup.

Hand assembled, hand test fired and built entirely from top tier components, this is the short .300 Blackout build most shooters would assemble themselves given the budget. Like every firearm, it ships to your local licensed dealer for transfer after your background check.
