The Sharps Bros Hellbreaker AR-15 Stripped Lower Receiver (brand part no. SBLR01) is a stripped AR-15 lower receiver for builders who want a distinctive receiver under their own choice of parts. Its design takes inspiration from the P-40 Warhawk fighter, with machined nose-art lines in place of the plain look of most AR-15 lowers. The Gen2 version adds a threaded bolt catch pin, reduced weight and improved styling. It suits a showpiece build or a daily rifle that stands out at the range.

Key Specifications

• The platform is the AR-15 pattern, so it accepts standard AR-15 uppers, buffer systems and furniture.
• The weight is 8.9 ounces, which keeps the finished rifle light.
• The receiver is machined top to bottom from 7075-T6 aluminum, a high-strength, corrosion-resistant alloy.
• The finish is a hard coat anodize per MIL-A-8625, the same anodizing standard used for many military and aerospace parts.
• The lower is marked multi-caliber, which suits builds across the AR-15 family of calibers.
• It is fully compatible with mil-spec internal parts, so a standard lower parts kit fits.
• It is fully compatible with aftermarket mil-spec upper receivers, which keeps upper choices open.
• An oversized, integral trigger guard gives a gloved finger more room.
• A beveled magazine flare helps guide magazines in for faster reloads.
• It works with GI-standard magazines as well as PMags, so existing magazines carry over.
