Key Features
- 16-inch 6MM Max barrel — why it matters: delivers flat trajectory and retained energy past 600 yards, giving you reach on coyotes, hogs, or steel without dragging a heavy rifle.
- B5 Bravo stock and grip — why it matters: rock-solid cheek weld and positive grip texture keep you on target in wet or dusty conditions, no slip.
- Type III hard coat anodized finish — why it matters: resists scratches, corrosion, and UV fade when riding in a truck rack or saddle scabbard.
- Two 20-round magazines included — why it matters: you get a spare mag out of the box, saving you $30–40 and a separate order.
- Mil-spec fire control group — why it matters: reliable, easy to upgrade later if you want a match trigger, but runs fine as-is for field use.
Who It’s For
Ranchers, rural workers, and utility shooters who need a rifle that works when called on. If you’re running fence lines, checking stock tanks, or punching paper at 300–600 yards, this Broadsword fits. Not for benchrest competitors or collectors—this is a working gun.
Pros / Cons
Pros: Accurate out of the box, good ergonomics, two mags included, tough anodized finish, 6MM Max offers less recoil than .308 with similar reach.
Cons: Ammo availability for 6MM Max is thinner than .223 or .308—you may need to order online. Stock trigger is serviceable but not match-grade.
