Upgrade your AR with the POF-USA Minuteman Complete Upper, a ready-to-run top end engineered for reliability, accuracy, and duty-grade durability. Anchored by a 16.5" black-nitride 5.56 NATO barrel and a rigid 14.5" free-float M-LOK handguard, this upper delivers flat-shooting performance, generous accessory mounting, and the sleek ergonomics that define the Minuteman line. A mid-length gas system with a low-profile direct-impingement gas block smooths recoil impulse and enhances parts longevity—perfect for fast strings at the range or serious training blocks.
Why Choose the Minuteman Upper
Duty-Grade Barrel: The 16.5" black nitride (melonite/QPQ) treatment hardens the bore and exterior for corrosion resistance, long life, and easy cleaning while preserving accuracy.
Mid-Length Gas = Smoother Shooting: A mid-length port location reduces dwell-time pressure vs. carbine systems, helping deliver flatter tracking and less wear.
Free-Float 14.5" M-LOK Handguard: Lightweight yet rigid, with ample M-LOK slots for lights, lasers, hand stops, bipods, and sling mounts—plus top rail sections for irons or accessories.
Precision Upper Receiver: 7075-T6 aluminum receiver with black anodized finish for strength and clean interface to your lower.
Low-Profile Gas Block: Tucks cleanly under the handguard for optimal accessory clearance and snag-free handling.
POF-USA Fit & Finish: American-made quality control, tight machining, and a reputation for rugged, reliable uppers.

Installation & Setup Tips
Attach to a standard AR-15 Mil-Spec lower using your takedown/pivot pins.
Use a quality BCG and charging handle for best reliability.
Torque and gas key integrity on your chosen BCG should meet spec; lubricate per your maintenance routine.
Confirm muzzle device timing (if adding or swapping) and apply appropriate shims/crush washer per manufacturer guidance.
If you’re not comfortable assembling AR components, a qualified armorer can install and verify function quickly and safely.
Maintenance & Care
Clean and lube at routine intervals; nitride barrels often require less scrubbing than chrome-lined equivalents.
Periodically verify gas block and handguard fasteners for torque.
Check muzzle device tightness after high-round-count sessions.
Compliance Notes
The 16.5" barrel exceeds the minimum rifle barrel length under federal law; overall legal status depends on your lower, muzzle device, and local/state regulations.
Always confirm compliance with all applicable laws before configuration and use.
