Precision-Made Lower Receivers for Your Rifles

At MSP, we manufacture industry-leading, precise assault rifle lower receivers for any custom AR-15 build. Our custom stripped lower receivers are machined from high-strength aluminum alloys that can be found in cars and aircrafts and are completed with various anodized finishes.

If you’re searching for the best stripped lower receiver for the base of your next build, our high-quality lowers are cost-effective, versatile, lightweight and strong. You can purchase more than one at a time to start multiple builds or save them as spares for the future.

When you buy a stripped lower receiver from MSP, we will ship it to an FFL dealer who will transfer it to you after a background check and required transaction record paperwork is complete.
