Blackout Defense’s AR-15 Mod-A lower receivers are engineered from the ground up to address structural design weaknesses in standard lower receivers and enhance overall tolerances.


– CNC machined from 7075-T6 American made billet aluminum

– Reinforced in critical areas such as the buffer tube and the trigger pin joins

– Wire EDM cut magazine well

– Laser engraved

– Flared magazine well for easy magazine changes

– Mil-Spec component compatible

– Over-sized trigger guard

– Threaded Bolt Catch Roll Pin – Allows for simple installation of the bolt catch and virtually eliminates the chance to damage the finish during installation (roll pin is included.)

– Threaded Trigger Slack Adjuster – Allows users to lock-in the trigger pins using a nylon tipped tensioning set screw inserted through the grip tang of the lower receiver. This prevents the trigger pins from waking out (green tip set screw is included.)

– Upper Tension Screw – Allows users to fine tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted through the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver (green tip set screw is included.)

– Type III Class 2 hard anodized

– Threaded Trigger Slack Adjuster and Upper Tension Screw are double-stacked to prevent the set screws from loosening (steel tip set screws are included.)
