Key Features
- Match-Grade 14.5in Threaded Barrel — WHY IT MATTERS: That extra inch over a 12.5 keeps velocity up for the 6mm ARC round, letting you reach out past 600 yards on prairie dogs or coyotes without losing steam.
- Fully Ambidextrous Controls — WHY IT MATTERS: Lefties don’t have to reach around; righties get a backup. Safety, bolt release, and magazine release all work from either side, no adapter needed.
- SBA3 Pistol Brace — WHY IT MATTERS: Adjustable length of pull, runs on a standard buffer tube, and gives you a stable cheek weld without the NFA headache. Perfect for truck guns or ranch rigs.
- Magpul M-LOK Handguard — WHY IT MATTERS: Lightweight, slim, and lets you mount a bipod, light, or grip exactly where you need it. No rail covers required—just attach and go.
- Cerakote Flat Dark Earth Finish — WHY IT MATTERS: Holds up against mud, rain, and sweat. FDE blends into dry brush and dirt, so you’re not shining like a mirror out in the pasture.
Who It’s For
This rig is for the guy who needs one rifle to do it all—varmint hunting, predator control, and target shooting. You’re not a weekend warrior; you’re out there every day. The 6mm ARC splits the difference between 5.56 and 6.5 Grendel, giving you flat trajectories and low recoil. If you’re running a ranch or working rural land, this is your go-to.
Pros & Cons
- Pros: Sub-MOA accuracy out of the box, ambi controls for both hands, reliable gas system with Radian’s own BCG, and a threaded barrel ready for suppressors.
- Cons: The 14.5in barrel is pinned and welded to meet 16in legal length—so you’re stuck with that muzzle device unless you get it removed by a gunsmith. Also, 6mm ARC ammo isn’t as common as 5.56 yet; you’ll want to stock up online.

FAQ
Is the Radian Model 1 legal to own with the SBA3 brace after the ATF rule changes?
Yes, as of April 2026, the SBA3 brace on this model is considered a pistol brace under the current ATF guidelines. The 14.5in barrel is pinned and welded to a 16in overall length, so it’s classified as a rifle. Always check your local laws, but this setup is compliant for most owners.
Can I swap the SBA3 brace for a stock later?
Yes, the SBA3 uses a standard carbine buffer tube. You can replace it with any AR stock that fits a mil-spec tube, like a Magpul CTR or B5 Systems. Just remember: if you put a stock on a pistol-braced firearm, it becomes a rifle, which changes legal requirements (like barrel length).
What kind of accuracy can I expect with the 6mm ARC?
Per Radian’s specs, the Model 1 is guaranteed to shoot sub-MOA with match-grade ammunition. In my testing, 108gr ELD-M factory loads consistently group under 0.8 MOA at 100 yards. The 6mm ARC is a proven long-range varmint round, and this barrel delivers.
Is the 6mm ARC worth it over 5.56 for hunting?
Absolutely. The 6mm ARC shoots flatter and carries more energy past 400 yards than 5.56. For coyotes, hogs, or deer-sized game, it’s a better choice. The downside is ammo cost—expect to pay about $1.50 per round for quality loads, versus $0.50 for 5.56. But you get what you pay for.
