7 Position AR-15 Buffer Tube with Unique Facets

The AR-15 buffer tube often gets neglected when considering builds or upgrades.  That’s because most are the same!  Not so with the Strike Industries Advanced Receiver Tube.  This receiver extension looks great, with facets cut into low-stress areas of the tube to save weight, and reduce friction with tight-fitting stocks.

Plus, the stock has an extra recess compared to most buffer tubes, allowing for finer length of pull adjustment with your favorite stock.  And to make installation easy, the buffer detent area is supported on both sides, ensuring you’ll have perfect alignment when threading in your new Strike Industries receiver extension.

NOTE: Not compatible with rifle length buffers or rifle length springs. Cannot work with the A5 buffer system. Internal length of buffer tube is the same as a standard carbine buffer tube.


  • 7-position mil-spec diameter buffer tube
