What lower receiver is compatible with a .308 AR-10 upper?

A .308 AR-10 upper requires a compatible large-frame lower receiver. Moriarti .308 upper assemblies are primarily designed for Moriarti Lowers and compatible DPMS/LR-308-pattern lower receivers. Because large-frame AR platforms are not universally standardized, fit can vary between manufacturers and receiver patterns. Always verify the upper and lower pattern, takedown and pivot-pin alignment, and manufacturer specifications before pairing components.
