For those that are looking for aftermarket support for the AR15 but require a larger cartridge, we present our Raw Aluminum AR10/.308 Lower. Our high-quality lowers are made using industry-leading CNC machines which create very tight tolerances.
To learn whether you should Anodize or Cerakote the lower, see our blog here!
Due to the lack of standardization, there are many different variants of the AR10/.308 platform, including our own AR10 80% lower receiver. Our 80% AR10 lowers follow the DPMS Gen 1 pattern which offers users the widest aftermarket support for your build.
We manufacture our 80% lower receivers with US-sourced aerospace grade 6061 aluminum. The material is more durable, resistant to corrosion, and yet much easier to mill than any other alloy.
DPMS Gen 1 Pattern Compatible
CNC Milled 6061 Aluminum Construction
Integrated Trigger Guard
Threaded Bolt Catch Screw Hole
Fire Selector Engraving
Completed Rear Takedown Lug Pocket
Full Mil-Spec Parts Compatibility
All of our billet lowers feature a threaded bolt catch pin hole. We do not include it with our AR10 lowers as they come standard with our AR10/.308 Lower Parts Kit. Already have a parts kit and need the screw? Buy our Bolt Catch Screw Kit!
*Please Note: Consult the manufacturer of your AR10/.308 build components to ensure compatibility with our lowers. Palmetto State Armory’s PA10 components will not fit our lowers.
