Product Details
This upper and lower receiver set is the foundation of a reliable semi-automatic rifle that shoots 223 Remington or 5.56 NATO ammunition. Mil-spec means it meets military standards for durability and compatibility, so you know it'll run dependably whether you're at the range or in the field. The flat dark earth finish is practical and easy to maintain. If you're building your first AR or adding to what you've got, this is a solid, no-nonsense choice.
