AR-15 Complete Lowers & Lower Receiver Assemblies
AR-15 Complete Lowers & Lower Receiver Assemblies
Shop AR-15 complete lowers from Moriarti for factory-assembled lower receiver configurations with installed lower components. Browse complete AR-15 lower receivers with different stocks, grips, triggers, furniture and finishes to match your preferred rifle configuration. Unlike stripped lowers, complete lowers arrive with the specified lower parts already installed. Compare each Moriarti lower for its exact furniture, buffer system, trigger, finish and included components.
What is the difference between a complete AR-15 lower and a stripped lower receiver?
A complete AR-15 lower has its specified lower components already installed, which may include the lower parts, trigger, grip, buffer system and stock or other rear configuration. A stripped lower is primarily the receiver and requires additional components. Exact equipment varies by model, so check each product listing for what is included.
