The Yankee Hill AR-15 Specter XL Carbine Upper Assembly come fully assembled and headspaced, ready to drop in on any standard AR-15 lower receiver. Upper assembly features a Mil-Spec 7075-T6 forged flattop upper and a 16" Chome-Moly barrel with Yankee Hill's Diamond Fluting which improves rigidity and increases surface area to speed barrel cooling. The upper includes a charging handle and bolt carrier assembly in addition to the Yankee Hill Specter XL quad rail Handguards which features an extended length 12 o'clock rail for an uninterrupted, monolithic top rail appearance. Full length side and bottom rail sections allow the mounting of lights, lasers, and other accessories while the diamond shaped vents reduce weight and allow for more rapid heat dissipation.
