Davidson Defense XRS3 Ambidextrous Side-Charging AR-15 Billet Upper Receiver
Upper Receivers mount and house the barrel, handguard, and gas system in a AR-15 or LR-308/AR-10. Custom upper receivers vary from Side Chargers, and Skeletonized uppers, to Rigidity Reinforced or 'Lite' receivers, where certain features such as the forward assist and brass deflector are removed to streamline the design. This also applies to most Pistol Caliber Carbine upper receivers with special ejection door cuts made specific for 9mm or .45ACP.
About this Upper: When Crosshill Tech went out of business, we decided that the market still needed a high-quality side-charging upper receiver. So we redesigned the upper with an enhanced look that matches well with any lower receiver, forged or billet. Now we have the best ambi side charge on the market. The Davidson Defense side charge upper has been tested and shown to perform better than any other in the market by independent testing.
Material: Billet 7075-T6 Aluminum - 7075-T6 Aluminum is a high strength alloy metal with great ductility, toughness, and resistance against fatigue. 7075-T6 was standardized for use in Aerospace equipment and aircraft. The Suffix T6 is a temperament treatment to increase the overall toughness and strength of the Aluminum. 7075-T6 Aluminum was chosen for the AR-15 platform for its ease of manufacturing, lightweight properties, and strength.
