Anodized Upper and Lower Combo
These combo kits include both an upper receiver and a lower receiver sold at a discount so you can get a set that matches from the same manufacturer. When choosing uppers and lowers from different manufacturers it is possible to have some minor fitment issues or coloring issues. Eliminate the likeliness of that with a set from the same manufacturer.
