These Uppers Have Minor Cosmetic Blems- 100% Functional Description The Sons of Liberty Gun Works stripped upper receivers are made to the tightest tolerances while still being compatible with Mil-Spec parts and upper receivers. This ensures that there is absolutely no wobble between receivers which can affect accuracy. These stripped AR-15 upper receivers are a great starting point for your next build. They are forged from 7075-T6 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 receivers go through a final machining process to eliminate flash marks and true up the tolerances to be better than MIL-SPEC. Finally, each AR upper is coated in a black hardcoat anodized type III with an R5 bright dip to further increase corrosion and wear resistance.
