M1 Machining is moving towards manufacturing the 80% lower receiver market known across America. We are working every day to ensure our product is higher quality, more user- friendly, and economically realistic for our fellow gun enthusiast. Our M1-80 AR15 and M1-80 AR10 DPMS .308 lower receivers are CNC'd out of 7075-T651 Aerospace aluminum. Our billet 80% lower receivers are a custom solution to their forged alternatives, and allow us to engineer and design for an aesthetically pleasing, quality lower receiver. Our facility only uses top quality carbide end mills to ensure we keep tolerances and maintain a high standard for quality. The M1-80 series lower receivers are second to none in value.
