Radian Weapons Model 1 — 6mm ARC 14.5″ Threaded Brown
About this product
The Radian Weapons Model 1 in 6mm ARC is a hand-assembled, match-grade upper receiver group paired with a pistol lower, built for precision shooting and requiring specific NFA compliance considerations due to its 14.5-inch threaded barrel length. This configuration ships as a factory-built unit with an SB Tactical SBA3 brace, providing an immediate platform for the 6mm ARC cartridge that excels at mid-range target engagement. Its construction from high-quality components like the ATC AR Gold trigger and Radian Raptor-SD charging handle prioritizes mechanical accuracy and suppressor-ready function right from the factory box.
What is the Radian Weapons Model 1 used for?
The Radian Model 1 is engineered for deliberate, precision-oriented shooting at ranges from 200 to 600 yards, where the 6mm ARC cartridge's ballistic efficiency shines. Its 14.5-inch barrel with a 1:8 twist rate optimally stabilizes heavier, high-BC projectiles like the 108gr ELD-M, making it ideal for disciplined target work, mid-range competitions, and varmint control where shot placement is critical. The suppressor-optimized Raptor-SD charging handle and M-LOK handguard make it a ready host for a sound suppressor and bipod, though its overall length of approximately 31 inches with the brace collapsed demands careful consideration for transport.
How does the Radian Model 1 compare to the Stevens 334 in .308 Win?
The Radian Model 1 in 6mm ARC offers significantly flatter trajectory and less recoil impulse for repeatable shots on steel or paper compared to the Stevens 334 Rifle in .308 Win, but sacrifices terminal energy and component availability. Where the Stevens 334 is a cost-effective, utilitarian bolt-action platform for hunting with widely available .308 Winchester ammunition, the Radian is a specialized semi-automatic system built for match-grade precision and rapid follow-up shots using the newer 6mm ARC, which runs about $1.10 per round for factory match ammo versus $0.85 for comparable .308. The Radian is better for the shooter prioritizing hit probability on a 10-inch target at 500 yards; the Stevens is better for the hunter needing reliable, powerful ammunition at any rural feed store.
What does it weigh and what are the dimensions?
Unloaded and without optics, the complete rifle weighs approximately 7.3 pounds (118 oz), with a length of 31.2 inches from the muzzle threads to the end of the fully collapsed SBA3 brace. The 14.5-inch cold hammer-forged barrel contributes to a balanced feel, with the aluminum handguard extending roughly 13 inches to provide ample real estate for a forward grip and bipod mounting, though adding a standard SOCOM 5.56 suppressor will increase overall length by about 6.8 inches and add roughly 1.5 pounds to the front end.
Who is this NOT for?
This rifle is not for a first-time AR platform buyer or someone unfamiliar with National Firearms Act regulations concerning barrel length and arm braces. The 14.5-inch barrel length, when paired with the included brace, creates a configuration that falls under intense and shifting ATF scrutiny, requiring the owner to stay current on regulatory determinations—a complexity avoided with a standard 16-inch rifle. It's also a poor choice for general plinking or budget-conscious shooting, as 6mm ARC factory ammunition costs nearly 30% more than 5.56 NATO and the platform’s $3,250 price tag is over four times that of an entry-level AR-15.
What's in the box?
The rifle ships as a complete, hand-assembled unit with one 20-round 6mm ARC-specific polymer magazine, the SB Tactical SBA3 adjustable brace installed, and Radian's lifetime warranty paperwork. Unlike some competitors, it does not include a basic optic, sling, or cleaning kit, as Radian assumes the buyer purchasing at this price point has specific preferences for these accessories—budget an additional $500-$1,500 for a capable magnified optic, rings, and a quality bipod like a Harris or Atlas to realize the rifle's full potential.
Is the Radian Model 1 worth it at $3,249.95?
At its price point, the Radian Model 1 is worth the investment only for the shooter who demands semi-automatic match-grade accuracy and is prepared to manage the regulatory landscape of a 14.5-inch barreled configuration. You are paying for the hand-assembled fit, the exceptional ATC trigger with a crisp 2.5-pound break, and the fully ambidextrous lower—features that, if purchased separately and assembled, would approach a similar cost without the integrated QC and single warranty. For a shooter whose needs are met by a standard 16-inch barreled rifle in .223 Wylde or who prioritizes simplicity, a platform like the Stevens 334 in .243 Win offers excellent out-of-the-box accuracy for less than one-third the price, sacrificing only the rapid follow-up capability and modularity.

Frequently asked questions
- Is the 14.5-inch barrel considered an SBR?
- As shipped with the SB Tactical SBA3 brace attached, this configuration's status is subject to current ATF rulings and interpretations, which have changed multiple times in recent years. It is the buyer's responsibility to consult with legal counsel or the ATF directly prior to purchase to determine if this configuration constitutes a Short-Barreled Rifle (SBR) under the National Firearms Act, which would require a Form 1 or Form 4 and a $200 tax stamp. We recommend treating it as an SBR from the outset to ensure full compliance.
- Does it work with standard AR-15 magazines?
- No, the 6mm ARC cartridge requires specific magazines due to its different case taper and overall length compared to 5.56 NATO or .223 Remington. The rifle includes one 20-round 6mm ARC-specific polymer magazine; additional magazines from manufacturers like Duramag or ASC are required for spares. These magazines are not interchangeable with standard AR-15 mags and typically cost between $25 and $40 each.
- Is the Cerakote brown finish durable?
- Yes, the applied Cerakote brown (Series H-146) is a professional-grade ceramic coating rated for over 500 hours of salt spray resistance, providing superior corrosion protection compared to standard phosphate or anodizing. It maintains a consistent matte finish to reduce glare, but like any coating, it can be scratched by hard metal-on-metal contact with range bags or racks—field use will show wear on high-contact edges like the magazine well and safety selector.
- How long does shipping take to an FFL?
- Processing and shipping typically take 3-5 business days from order verification to departure from our warehouse, followed by ground transit time to your selected Federal Firearms License (FFL) holder, which averages 2-7 additional business days depending on location. You must provide your FFL's contact information and a copy of their license before the firearm ships, and you will need to complete a Form 4473 and pass a NICS background check in person at the FFL before taking possession.
