Radian Model 1 6mm ARC 14.5in Threaded SBA3 FDE 20+1

About this product

What is the Radian Model 1 6mm ARC 14.5in Threaded SBA3 FDE 20+1? It's a semi-automatic AR-platform rifle built for precision, featuring a match-grade 14.5-inch threaded barrel chambered in 6mm ARC, a fully ambidextrous control layout, and an SBA3 pistol brace, all finished in Cerakote Flat Dark Earth. This rifle is hand-assembled from high-grade components with a focus on mechanical consistency and modularity, making it a tool for shooters who demand repeatable accuracy from a compact format. Its configuration, particularly the threaded barrel and brace, places it directly in a regulatory category that requires specific understanding from the owner.

What is the Radian Model 1 used for?

This rifle is engineered for intermediate-range precision shooting and tactical training where compactness and suppressor use are priorities. The 6mm ARC cartridge, paired with the 14.5-inch threaded match-grade barrel, is optimized for consistent performance out to 600+ yards, making it superior for varmint control or mid-range target work compared to standard 5.56 NATO platforms. The SBA3 brace and overall configuration suggest a build intended for mobile, dynamic use rather than purely bench-rest shooting, and the Dead Air Keymo muzzle device is a direct invitation for suppressor attachment.

How does the Radian Model 1 compare to a Stevens 334 Rifle in .308 Win?

The Radian Model 1 prioritizes rapid follow-up shots and modularity, while the Stevens 334 Rifle in .308 Win is a dedicated bolt-action platform for ultimate long-range precision from a fixed position. The Stevens 334 will deliver marginally better inherent accuracy from its 20-inch barrel and locked breech, but the Radian's semi-auto action allows for engagement of multiple targets faster—a critical difference for tactical scenarios or predator hunting. For a shooter needing one precise shot on a stationary target at 800+ yards, the Stevens is better; for engaging several targets between 200-600 yards under time, the Radian is the superior tool.

What does it weigh and what are the dimensions?

Unloaded and without an optic, this rifle weighs approximately 6.8 pounds (3.1 kg), with an overall length of 28.5 inches from the end of the buffer tube to the muzzle threads. The handguard measures 13 inches, providing ample real estate for mounting lights, lasers, and vertical grips via the integrated M-LOK slots. The balance point is just forward of the magazine well, making it feel slightly muzzle-heavy—a design choice that aids in recoil management during rapid fire but requires a more active support hand.

Who is this NOT for?

This rifle is not for a first-time firearm owner or someone unwilling to navigate ATF regulations concerning pistol braces and short-barreled rifles (SBRs). It's also a poor choice for general plinking with cheap ammunition; 6mm ARC match-grade ammo costs roughly $1.80 per round, making sustained fire an expensive endeavor. If your primary use is inside 100 yards or you prioritize the lowest possible cost-per-shot, a rifle in 5.56 NATO or a shotgun like the Stevens 555 Sporting O/U would be a more practical and economical selection.

What's in the box?

You receive the complete rifle with the SBA3 brace installed, one 20-round 6mm ARC magazine, a Dead Air Keymo flash hider already threaded and torqued to the barrel, and the manufacturer's documentation including a test-fire target. Notably, it does NOT include iron sights, an optic, a sling, or a case—these are essential add-ons that will increase your total investment by several hundred dollars. The packaging is functional, not retail-friendly, reflecting its direct-to-consumer 'Online Only' sales channel.

Is the Radian Model 1 worth it at $3249.95?

Yes, if your use-case explicitly justifies its specialized configuration and premium components. You are paying for the hand-fitted upper and lower receivers, the fully ambidextrous machining (not just add-on levers), the match-grade barrel, and the high-end adjustable two-stage trigger—features that collectively cost over $1,500 to replicate in a custom build, not including the gunsmith's labor. For a shooter who needs this specific blend of compact precision and semi-auto capability, it's a justified expense. For someone who just wants "an AR," a $1,200 off-the-shelf rifle will be 90% as effective for 50% less money.
