Gen 3 Forged Lower Receiver

DISCONTINUED

While our forged lower receivers exhibit a very high level of fit and finish, it’s simply not just the quality of the machining that separates Umbrella lowers from the rest. We are meticulous with our inspection protocol to ensure every receiver shipped represents premium manufacturing synonymous with the brand. We’ve added a simple chamfer to the grip interface for easy installation of even the most stubborn designs. And unlike many forged lowers, our magwell bevel is extreme for faster reloads. The deep laser engraved umbrella consumes thirty minutes of machine time alone but it’s the only way to get such a crisp and well-defined logo. The excellence is in the details. Umbrella Corporation AR-15 forged lower receivers are made to the finest standards and carry an unconditional guarantee against material defect and manufacturing failure. Assembly by a qualified Armorer is required.
