POF UPPER COMPLETE WONDER 13.75 5.56 BLUE

The POF Complete Upper Receiver Wonder 13.75" 5.56 NATO in blue finish is a ready-to-mount upper assembly built for shooters who demand precision and reliability without compromise. Patriot Ordnance Factory engineered this upper around a mid-length gas system with a Dictator adjustable gas block, giving you the tuning capability to dial in your rifle's performance whether you're running suppressed or unsuppressed, with standard or heavy ammunition. The 13.75" nitride-treated barrel is built tough for consistent accuracy and longevity, while the pinned and welded Dead Air Keymo muzzle brake delivers manageable recoil and a proven interface for sound suppressors.

This is a complete upper—no stripped receiver or mystery parts. The 13 Renegade rail system provides plenty of real estate for optics, lights, and tactical accessories, and its modular design keeps the upper lightweight and agile. The blue titanium finish isn't just for looks; it protects against corrosion and wear while giving your rifle a distinctive, professional appearance on the range or in the field. Whether you're building a precision rifle, upgrading an existing platform, or assembling a do-everything 5.56 that handles duty, suppressor use, or hunting roles, POF's attention to component selection and manufacturing standards means you're starting with upper-tier quality.

This upper pairs with any standard AR-15 lower receiver. If you're familiar with POF's reputation for combining innovation with shooter-first design, the Wonder delivers on both fronts—no marketing fluff, just purpose-built hardware.

Can I use this upper with a suppressor?

Yes. The upper comes with a Dead Air Keymo muzzle brake that is pinned and welded in place, and it accepts Dead Air suppressors and other suppressors with Keymo mounts. The adjustable Dictator gas block also allows you to tune the rifle for suppressed and unsuppressed shooting.

What's included—is this truly complete?

Is the muzzle brake permanently attached?

Yes, the Dead Air Keymo muzzle brake is pinned and welded to the barrel, so it cannot be removed. This configuration is permanent and designed for reliability and durability.
