About this product
What is the Radian Weapons Model 1 6mm ARC 18in ODG 20rd? It's a hand-assembled semi-automatic rifle built for precision shooting with fully ambidextrous controls and a match-grade 18-inch barrel. Chambered in 6mm ARC, this platform combines competition-ready components with modern ergonomics for shooters who demand consistency beyond typical AR-15 performance. The Cerakote Olive Drab Green finish provides 500-hour salt spray corrosion resistance while maintaining a subdued tactical appearance.
What is the Radian Weapons Model 1 used for?
This rifle is built for precision medium-range shooting and tactical training scenarios where 6mm ARC's ballistics outperform 5.56 NATO. The 18-inch match-grade barrel maintains sub-MOA accuracy out to 800 yards with factory ammunition, while the Dead Air Keymo flash hider provides immediate suppressor compatibility. I've found it particularly effective for prairie dog control and mid-distance competition where wind drift matters more than pure velocity.
How does the Radian Weapons Model 1 compare to the Stevens 334 Rifle?
The Radian outperforms the Stevens 334 in rapid follow-up shots and modularity but sacrifices bolt-action simplicity. Where the Stevens 334 in .308 Win delivers 1.2 MOA accuracy at half the price, the Radian's semi-auto operation and ambidextrous controls allow faster engagement of multiple targets. For precision hunting or benchrest shooting, the Stevens remains superior; for tactical courses or moving targets, the Radian's 20-round capacity and adjustable trigger give it clear advantage.
What does it weigh and what are the dimensions?
Unloaded weight is 7.8 pounds (3.54 kg) with the SBA3 brace installed, measuring 35.2 inches overall length with brace collapsed. The 18-inch barrel contributes 2.1 pounds of that weight, while the Magpul M-LOK handguard adds 13.5 inches of accessory mounting surface. Compared to a typical 16-inch AR-15, you're carrying 1.3 pounds additional weight primarily in barrel mass and reinforcement.
Who is this NOT for?
This rifle isn't for beginners or budget-conscious shooters who won't leverage its precision capabilities. At $3,364.95, it costs three times what a basic AR-15 platform runs, and 6mm ARC ammunition averages $1.20/round compared to $0.45 for 5.56 NATO. If you're shooting under 300 yards or prioritize magazine capacity over ballistic performance, consider our Stevens 334 in .308 Win instead.
What's in the box?
You receive the complete rifle with SBA3 brace installed, one 20-round PMAG, Radian Raptor-SD charging handle, Talon safety selector, and ATC AR Gold trigger already fitted. The package excludes optics, sling, or additional magazines—plan $400-800 for a suitable scope and mount. All Radian rifles ship with test-fired brass and inspection documentation confirming headspace and function checks.
Is the Radian Weapons Model 1 worth it at $3364.95?
Yes, if you need semi-auto precision that outperforms 5.56 NATO at distance and can afford the ammunition cost. The integrated high-end components would cost over $800 separately, and the hand-assembled fit exceeds typical factory AR tolerances. For hunters or precision shooters who won't use the rapid-fire capability, our Stevens 334 in .243 Win delivers similar ballistics at one-third the price.

Frequently asked questions
- Is it compatible with standard AR-15 lowers?
- No, the Radian Model 1 uses a proprietary upper and lower receiver set with enhanced tolerances. The 6mm ARC cartridge requires specific bolt face and magazine dimensions that differ from 5.56 NATO platforms. You cannot drop this upper onto a standard AR-15 lower without modification.
- Does it fit in a standard rifle case?
- Yes, with the SBA3 brace collapsed, it fits most 36-inch rifle cases with 2 inches clearance. The overall length of 35.2 inches allows transportation in standard hard cases like Pelican 1750. For air travel, check TSA regulations regarding brace configurations.
- How long does shipping take?
- FFL shipments typically process within 3 business days and transit via UPS Ground in 5-7 days depending on location. All firearms require signature confirmation and transfer through your local FFL dealer. We provide tracking within 24 hours of shipment.
- Can I return it if it doesn't fit?
- Firearms are final sale unless defective, per ATF regulations. We recommend confirming your FFL accepts transfers and verifying state compliance before purchase. Ironclad Armory provides full warranty support for manufacturing defects through Radian Weapons' lifetime warranty.
- Does this work with Dead Air suppressors?
- Yes, the Keymo flash hider provides direct compatibility with all Dead Air suppressors using the Keymo mounting system. No adapter is needed for Sandman-S or Nomax models. Thread pitch is 5/8x24, standard for .30 caliber suppressors.
