POF UPPER COMPLETE WONDER 13.75 5.56 BLUE$1,206.00
Availability: In Stock
The POF Wonder 13.75" complete upper in .300 Blackout delivers a no-nonsense, ready-to-run upper receiver assembly built for shooters who want proven components without compromise. Patriot Ordnance Factory pairs a mid-length design with a Dictator adjustable gas block to let you tune the platform to your suppressed or unsuppressed rounds—critical flexibility when running subsonic .300 Blackout. The 13.75" nitride barrel is built for durability, and the pinned and welded Dead Air Keymo muzzle brake is already integrated, so you're mounting-ready out of the box.
The 13" Renegade rail system gives you real estate for optics, lights, and accessories without excessive weight. Everything wears the blue titanium finish—a clean, modern look that also resists corrosion. Whether you're building a suppressed hunting rifle, a subsonic range gun, or a home-defense AR, this upper handles the job with POF's reputation for tight tolerances and no marketing fluff behind it.
Because it's a complete upper, you'll need a lower receiver and bolt carrier group to finish the build—but the hard work is done. Install, mount your optic, and get to the range or field.
| Caliber | .300 Blackout |
| Barrel Length | 13.75" |
| Barrel Finish | Nitride |
| Gas Block | Dictator (Adjustable, Mid-Length) |
| Muzzle Device | Dead Air Keymo (Pinned & Welded) |
| Rail System | 13" Renegade |
| Upper Finish | Blue Titanium |
| Type | Complete Upper Assembly |
You'll need a lower receiver and a bolt carrier group. The POF Wonder upper handles the barrel, gas system, rail, and muzzle brake—everything else bolts on.
The upper comes with a pinned and welded Dead Air Keymo muzzle brake. The adjustable Dictator gas block lets you tune the action to work reliably with suppressed .300 Blackout ammunition, which is a major advantage for subsonic shooting.
A 13.75" barrel is a practical middle ground for .300 Blackout rifles. It's short enough for home defense, hunting, or suppressed use, but long enough to avoid excessive gas port velocity swings. The Dictator adjustable gas block lets you dial in reliability whether you're running subsonic or supersonic loads.
The Dead Air Keymo muzzle brake on this upper is pinned and welded, which means it's permanently attached. This ensures a solid, repeatable zero—important for precision work.
