CMMG AR-15 Lower Parts Kit Tan is the configuration on this listing. No separate caliber is printed on this listing, so this description does not invent one. The listed color is Tan. Additional information repeats only the stored manufacturer, model, and the fields that came with this row. If a measurement is not in that list and is not in the name, this page does not supply it. Nothing here states an overall length, a weight, or a sound rating.

When two Cmmg listings look alike, compare caliber, finish, color, and model name only where those fields are filled in. This page is CMMG AR-15 Lower Parts Kit.
