Spectre Arms’ AR-15 80% Lower Receiver

The Spectre Arms’ AR-15 80% Lower Receiver is a top quality MIL-SPEC product.  The quality starts with the 7075-T6 Aluminum which is completed to 80% with precise tolerances on CNC equipment. Often when buying parts from multiple manufacturers, MIL-SPEC or not, you will end up with different tolerances. The SA Lowers have a built in slack out adjustment screw or SOAS built in to the lower receiver. The SOAS is located behind the handle screw hole and is used to take the slack out from the upper and lower receivers. In our experience, a properly milled lower will not have much if any slack, but this feature gives you the ability to adjust where other lowers can’t. Being a MIL-SPEC AR-15 80% lower receiver allows this to be finished with an array of Jigs on the market as well as countless customization options.  Also, our receivers are always Hard Coat Anodized with the 8625 Type III Class 2 finish.  Therefore, this process makes for a beautiful resilient finish that is always smooth and uniform as well as corrosion resistant.  Lastly, a broached magazine well ensures a perfect fit.
