The 80% Lower Patriot Pack is a three-pack of unfinished AR-15 lower receivers from Polymer80. Machined from forged 7075-T6 aluminum, these blanks are built to the same mil-spec standards as finished lowers. They arrive in a raw, unfinished state, requiring you to complete the fire control pocket and drill the trigger and selector holes to create a functional, serialized firearm for .223/5.56 platforms.
