The CMC Triggers AR-15 8-Position Buffer Kit is a complete buffer tube assembly built around an A5-length buffer, giving an AR-15 build the full set of components needed for the buffer system. The tube is machined from 6061-T6 aluminum and finished with MIL-A-8625 Type III, Class 2 hard anodizing, and it carries precision drainage holes intended for marine environments. The kit ships with a castle nut and a QD receiver end plate, so the assembly arrives ready for installation rather than as loose parts. The eight-position adjustable tube allows the stock position to be set across the full range of adjustment. With military-specification materials and finish, the kit is aimed at AR-15 builds that need a buffer system suited to demanding conditions.
