Sharps Bros Billet Upper Receiver – AR15 | SBUR04

Precision. Compatibility. Aesthetic Match.

The Sharps Bros SBUR04 Billet Upper Receiver (AR15) is the perfect top-half companion to your Sharps Bros lower. While any mil-spec upper will fit, this is the upper that matches perfectly in both aesthetics and tolerances. Machined from 7075-T6 billet aluminum and finished with a Mil-Spec Type III hard coat anodizing, this upper is built for long-term durability, tight fitment, and seamless performance.

Designed for builders who demand precision fit and top-tier looks, the SBUR04 is optimized for .223, 5.56, .224 Valkyrie, 300 Blackout, and 6.5 Grendel platforms.

⚙️ Key Features:

• Precision-Machined from 7075-T6 Billet Aluminum – Stronger and more rigid than forged receivers

• Mil-Spec Type III Hardcoat Anodized (Black) – Corrosion-resistant, wear-hardened finish

• Perfect Match with Sharps Bros Lowers – Seamless lines, matching dimensions, and premium aesthetics

• Universal AR15 Compatibility – Fits all standard barrel nuts and AR15 handguards, including those with anti-rotation tabs

• Caliber Compatibility – Ideal for .223, 5.56 NATO, .224 Valkyrie, 300 BLK, and 6.5 Grendel (not compatible with 450 Bushmaster, 458 SOCOM, or 50 Beowulf)

• Forward Assist Kit & Dust Cover Pre-installed – Ready to mount and run out of the box

• Subtle Sharps Bros Branding – “SHARPS BROS.” engraved discreetly on both sides

• Weight: ~9 oz – Balanced for performance builds

🧰 Why Builders Choose the SBUR04

When building a custom AR15, your upper receiver should be more than “just compatible.” It should fit precisely, align perfectly with your handguard, and match the aesthetics of your lower — especially if you’re running a Sharps Bros Warthog, The Jack, Overthrow, or Livewire lower.

The SBUR04 is built with purpose: to give your build a rock-solid upper that’s just as battle-ready and beautiful as your lower. Whether you're building for the bench or the field, this billet AR15 upper is the professional’s choice.
