Hellbreaker: distinctive appearance is inspired by the P-40 Warhawk, which was one of the United States most-produced fighter planes when World War II began. The nose art that became a popular military tradition was born from the practical need to identify friendly units, but eventually evolved to express a squadron's individuality. Considering the vast majority of AR-15 lowers look the same, Sharps thought it was time to improve upon the standard and create some visual diversity in the market. The fierce Hellbreaker lines are where looks meet performance: it takes painstaking detail work to machine each tooth point and eyebrow curve, but Sharps Bros never skimps on quality along the way. When you hold a Hellbreaker, you're holding one of the finest, most unique M4/AR-15 lower receivers in the world.
