Customize TNA Buffer Tube Kit (Mil-Spec)

This is a complete buttstock kit including the buffer tube, buffer, standard spring, castle nut, and end plate, but no stock. Great kit if you are doing a repair or if you want to bring your own aftermarket buttstock. Convert a fixed-stock AR-15 to an M4 configuration or complete your stripped lower on the cheap. Also useful for completing a Sabertooth or other chassis that uses AR-15 buttstocks.

The buffer tube has 6 position notches to meet the needs of different-sized shooters in a variety of shooting positions. This is ready to install on any AR-15 lower so long as the buffer tube threads are in spec (some Norinco's use weird threads).

  • Flat-back buffer tube
  • 6061 T6 Aluminum, anodized for a long service life

    You get:

    • Six-position Mil-spec buffer tube
    • Standard receiver end plate
    • Standard buffer spring
    • Buffer (3oz)
    • Castle nut

      Compatible with:

      • Standard-spec AR-15/M16 lower receivers and other firearms that have the same butt(stock) hole
      • Works with plastic, aluminum and other metal lowers
      • Mil-spec (NOT commercial) buttstocks

      Installation Difficulty:

      Tools required:  Armourer's wrench or castle nut wrench for the castle nut. We also recommend applying Aeroshell 33MS assembly grease to the Buffer Tube threads.

      Note: sometimes the castle nuts come from our supplier with rough threads, in which case we chase the threads with a bolt to smooth them out for you. It might look like the nut has been used but it's just our love marks.
