Sharps Bros Hellbreaker AR-15 Stripped Lower Receiver

Sharps Bros Hellbreaker Stripped Lower Receiver

The Hellbreaker represents a thoughtful approach to AR-15 lower receiver design, drawing inspiration from the legendary P-40 Warhawk fighter aircraft. This is a stripped lower receiver—the regulated firearm component—requiring a lower parts kit, buffer, and stock of your choice to complete.

Construction & Design

Machined from premium 7075-T6 aluminum, the Hellbreaker is built to exacting standards. The receiver features an oversized and integral trigger guard that provides excellent ergonomics and protection. A beveled magazine flare ensures smooth, reliable magazine changes with both standard GI magazines and modern polymer options like Magpul PMags.

Compatibility & Versatility

This lower receiver is fully compatible with:

• All mil-spec internal parts and fire control groups
• Any mil-spec upper receiver
• Standard GI-issue magazines and aftermarket mil-spec magazines
• Multi-caliber configurations (marked accordingly)

Specifications

• Material: 7075-T6 aluminum
• Finish: Black anodized
• Weight: 9.9 oz
• Compatibility: Mil-spec AR-15 platform

What You Need to Complete Your Build

As a stripped lower, you'll need to source a lower parts kit containing the trigger group, hammer, safety selector, and other internal components. You'll also need a buffer tube assembly with buffer and spring, plus a stock of your preference. This modular approach lets you customize your rifle exactly to your specifications.
