What do I need to complete a .338 ARC AR-15 kit?

Moriarti .338 ARC AR-15 kits are offered as component packages that do not include the lower receiver. Exact contents vary by kit, so review each product listing for the included upper assembly, bolt carrier group, charging handle, lower components, buffer system, furniture, and other parts.
