M1 Machining is proud to offer the M1 80 Milling Test Brick.  M1 Machining pushes the limits with innovative ways to make owning an AR15 80% Lower Receiver and AR10 LR 308 80% Lower Receiver more affordable to the end users.  M1 Machining’s M1-80 Milling Test Brick is designed to allow a cost effective way to practice making a fire control pocket without having to learn on your finished product. We have received requests from our customers that a test brick would have saved them money and given them a better finished product having the opportunity to learn and get a feel for the process without the pressure of perfection.  This is a great tool to learn for users who may not have as much experience working with aluminum.
