Our lower Receivers are CNC machined from a high-strength, 7075 T6 aluminum forging for reliable performance and outstanding durability. Machined to Military Specifications & Standards and marked “Multi-Cal” to be used with multiple calibers on the AR-15 platform. This Lower Receiver comes in type III black hard anodize, and an Open Trigger. Don’t over pay for the same lower receiver with a different logo and use your money saved elsewhere on your build. Pair this with one of our upper receiver for a solid fit for your AM-15 build.
