Coronado Arms Lower Receiver

The post documents the acquisition of components for a custom AR-15 build, focusing specifically on the lower receiver and associated parts kit.

• The primary component is a billet lower receiver, the Coronado Arms CA-15, machined from 7075-T6 aluminium.
• A complete parts setup was sourced from Palmetto State Armory (PSA), which included a buffer tube and a basic Magpul MOE stock.
• The author notes that the billet design contrasts with the forged lowers typically used on models like the M&P15T.
