What lowers are compatible with a .243 Winchester AR-10 upper?

A .243 Winchester AR-10 upper requires a compatible large-frame lower receiver. Moriarti .243 Winchester uppers are primarily designed for Moriarti and compatible DPMS/LR-308-pattern lowers. Because large-frame AR platforms are not universally standardized, fit can vary between manufacturers. Verify the receiver pattern and manufacturer specifications before pairing components. The .243 Winchester uses the same .308-family bolt face, making it well suited to compatible large-frame AR configurations.
