First Run Forged Lower Receiver

Inventory: Out of Stock
Price: $135.00

These receivers were our very first attempt at a forged lower. And like our current production models they exhibited a very high level of fit and finish with an extremely time consuming deep laser engraving process used for the large Umbrella logo. Unique to this model were the small umbrellas that we added at the full-auto selector position. We learned a great deal from this initial run and while these were premium lowers, our pricing at the time did not adequately reflect the costs associated with manufacturing. Some aspects of the design have made their way to our current forged lowers, some features have been dropped, with improvements added to our new receivers where required. Only 120 were manufactured.
