Ruger Harrier 28600 First Look — the 2026 Ruger AR-15

Ruger closed out 2025 by announcing the Harrier, a re-engineered modern sporting rifle line that takes over from the AR-556. Model 28600 is the one most people will see first: a 16.1-inch 5.56 NATO carbine built at Ruger's Hebron, Kentucky plant, listed at $749 MSRP.

What changed from the AR-556

Three things stand out. The first is the mid-length gas system on a 16-inch barrel, which is the configuration most builders choose on purpose: a softer impulse, more dwell time, and more tolerance for a suppressor than a carbine-length port gives. The AR-556 shipped carbine-length for most of its life.

The second is the handguard. A free-float M-LOK tube with a continuous top rail replaces the older setup, so the barrel is no longer loaded by whatever is clamped to the front end, and mounting a light or a bipod stops affecting point of impact.

The third is the small one that says the most about the design intent: an integrated tension screw that lets you take the play out of the upper-to-lower fit. That is an accuracy-and-feel detail normally found on rifles well above this price.

The parts that stayed mil-spec

Ruger left the trigger, the buffer tube and the receiver dimensions standard. That is deliberate and it is good news: every aftermarket trigger, stock, grip and charging handle on the market drops in. The mil-spec single-stage trigger is the first thing most owners will change, and a nitrided government profile barrel is a durable, unremarkable choice that will do what it is asked.

Where it lands

At $749 MSRP the Harrier is priced against the mid-tier of the market rather than the bargain shelf, and the feature list supports that: free-float rail, mid-length gas, threaded nitrided barrel, Magpul furniture and forged 7075 receivers. It is not trying to be the cheapest AR on the rack, and it is not competing with rifles at twice the price. It is the configuration most people end up building anyway, sold assembled.

Worth waiting for a batch to reach the field before drawing conclusions on longevity — it is a new line from a newly acquired factory. On the specification sheet it is a sensible rifle at a sensible price.
