Machined Billet Construction With Mil-Spec Or Self-Lubricating EXO Finish

Flattop upper receiver machined from a solid billet of 7075 aluminum has reinforced stress points for unsurpassed strength and durability. Unique, non-GI contours give your rifle a distinctive appearance, yet fits any standard mil-spec lower receiver, bolt, and bolt carrier. Includes pre-installed ejection port cover and forward assist assembly. MIL-STD 1913 Picatinny rail has 14 cross slots. Available with the traditional mil-spec, hardcoat anodized finish or proprietary EXO coating by UCT Coatings for an exceptionally wear-resistant surface that’s 40% harder than chrome. High-lubricity EXO finish eliminates the need for oil, grease, or additional lubricant. Ultra-low coefficient of friction results in less heat generated by metal-to-metal contact, keeping the weapon cooler so parts last longer. Won’t rub off, thin out, attract fouling, or build up residue, so gun is easy to clean, too.
