The Andro Corp Industries AR-15 stripped upper receiver is a 7075-T6 aluminum upper for builders who want to choose their own internals (ACI part no. URS). Andro Corp, an American AR manufacturer that builds its own rifles and pistols, finishes it with Type 3 hard coat anodizing and a dry film lubricant. M4 feed ramps are cut into the receiver, so it pairs with barrels using M4 extension ramps. It is machined to accept a forward assist and an ejection port assembly, which are not included, so you can fit the parts you prefer. At 6.2 ounces, it makes a light, solid base for your next upper build.
