The Sons of Liberty Gun Works stripped lower receivers are made to the tightest tolerances while still being compatible with MilSpec parts and upper receivers. This ensures that there is absolutely no wobble between receivers which can affect accuracy. These stripped AR15 lower receivers are a great starting point for your next build. They are forged from 7075T6 aluminum which is known for its high strength and crack resistant properties while also being lighter than 6061. After the forging process is complete the Angry Patriot lower receivers go through a final machining process to eliminate flash marks and true up the tolerances to be better than MilSpec. Finally each AR lower is coated in a matte black hardcoat anodized type 3 class 2 finish to further increase corrosion resistance. Like the name implies the magazine well features the angry patriot 1776 logo and has three position safety selector markings.
