The Tapco 6-Position Buffer Tube (brand part no. TAP22057) is a carbine receiver extension that gives an AR-pattern build six stock positions for length-of-pull adjustment. Tapco builds the tube for collapsible carbine stocks, letting shooters set the stock length for armor, body size, or shooting position and change it in seconds. Among AR buffer system parts, this tube favors builders replacing a worn extension or converting a fixed-stock lower to a collapsible setup.
