Cerro Raw 80 Percent Lower with Optional Safety Engraving
Forged by Cerro, this 80 percent lower is not an FFL item and is classified by the ATF as a non-firearm. Made from 7075 T6 heat-treated aluminum, this lower features flared and broached magwells and is "finished in white", tumbled and ready to be bead blasted before anodizing or cerakoting. All that's required is machining of the trigger and the safety well before it's a fully functional, mil-spec lower receiver. Click on the Magwell and Safety tabs to see some of the available engravings to choose from on your lower receiver.
Don't forget to select 1 of the 28 different safety markings from the drop down menu. The safety engraving reference chart can be seen under the "CHART A" tab above. Engraving will be on both sides of lower.
Designed to work perfectly with our selection of upper receivers and other AR parts and build to withstand rugged use, this lower receiver allows you to fully customize your AR15 build easily and quickly. Review the lower's specifications and shop today for the best pricing around.
