Sons Of Liberty Gun Works Receiver End Plate Features The Sons Of Liberty Gun Works Receiver End Plate is a factory OEM component machined from steel to Mil-Spec AR-15 dimensions. It sits between the lower receiver and the castle nut providing the correct bearing surface so the buffer tube assembly torques down properly and stays secure under recoil. The black finish matches standard Mil-Spec AR-15 hardware for a clean factory correct appearance. Because it is a direct OEM replacement it fits Mil-Spec AR-15 and AR-308 lower receivers without modification. Builders assembling a new lower or replacing a worn or damaged end plate will find this part a simple drop-in fix. It works alongside a castle nut and receiver extension to complete the buffer tube assembly and its Mil-Spec sizing means it pairs correctly with standard AR-15 stocks and buffer tubes. Sons Of Liberty Gun Works produces this end plate to the same tolerances expected of quality AR-15 hardware. This makes it a dependable choice for both first builds and routine maintenance on an existing rifle.
