The UTG Buffer Tube is a .308 mil-spec, 6-position carbine buffer tube machined from aluminum and finished in black, brand part number TLU002. It is sized to the wider .308-pattern mil-spec diameter rather than the standard 5.56 tube, so it is built specifically for .308 AR-platform builds and will not interchange with a 5.56 stock or buffer. The 6-position design lets shooters adjust stock length to fit their build and body type, and this listing is for the buffer tube only, which measures 8 inches long, without a stock, buffer, or spring included.
