This is a complete lower build kit for the AR-10 and LR-308 platforms. It includes a USA-made, serialized lower receiver, a mil-spec lower parts kit with trigger and grip, a heavy-duty carbine buffer tube, an adjustable nylon stock, and all required springs and pins. Everything you need to complete a lower receiver except the upper assembly.
This kit is designed for both AR-10 and LR-308 pattern rifles. The lower receiver, buffer tube, and springs are dimensioned to work with standard AR-10 and LR-308 upper assemblies. Verify upper assembly compatibility before purchasing, as some manufacturers use proprietary dimensions.
The kit includes a Spring Dynamics extra-power buffer spring manufactured in the USA with chrome-silicon construction and moly plating. This spring is stress-relieved and designed for extended service life without performance degradation. The 3.7 oz carbine buffer pairs with the 6-position buffer tube to manage recoil across different shooting scenarios.
The nylon reinforced polymer carbine stock offers six adjustment positions, allowing you to dial in length-of-pull based on your shooting position, gear, or preference. The adjustable design makes this kit flexible for different shooting applications without requiring stock replacement.
The mil-spec lower parts kit includes the fire control group and A2 grip, eliminating the need to source trigger components separately. All pins, springs, and small parts required for lower receiver assembly are included.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Upper assembly not included.
