Yankee Hill Machine Company Black Diamond Handguard Features The Yankee Hill Machine Company Black Diamond Handguard uses a free-floating design that isolates the barrel from contact pressure helping preserve accuracy on builds where barrel harmonics matter. Its top rail is a T-marked extended Picatinny section giving shooters a consistent uninterrupted mounting surface for optics and iron sights across the full length of the handguard. M-LOK slots positioned at the 3 6 and 9 o clock positions let users mount lights grips slings and other accessories exactly where they are needed without adding unnecessary bulk. The rifle length sizing suits full-length gas system builds giving shooters ample real estate to configure a setup to their preference. Constructed from aluminum the Black Diamond Handguard keeps the overall weight of a build down while maintaining the rigidity needed for a stable shooting platform. At 12.3 ounces it adds minimal mass compared to bulkier quad rail designs which matters for shooters running precision or long-range configurations where every ounce counts. The handguard ships complete with its barrel nut and wrench simplifying installation for builders assembling their own upper. The Yankee Hill Machine Company Black Diamond Handguard gives AR-15 owners a slim durable rifle length free-float option backed by a well-known name in AR accessories.
