This Tapco buffer tube kit gives AR builders and upgraders the receiver extension hardware needed to mount a collapsible stock. Tapco built its name on affordable, functional parts for America's most popular rifle platform, and a buffer tube kit is one of those pieces every build bench needs — whether you are completing a stripped lower, replacing worn components, or converting a fixed-stock rifle to adjustable. Straightforward installation with common armorer tools makes this an easy afternoon upgrade.
