This is a complete buttstock kit including the Buffer Tube, Buffer, standard Buffer Spring, Castle Nut, Recevier End Plate, and Tapco-like stock. Convert a fixed-stock AR-15 to an M4 configuration or complete your stripped lower on the cheap. Also useful for completing a Matador Sabertooth or other firearm chassis that uses AR stocks.

The stock is collapsible and 6-position 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 Upper Receiver's buffer tube threads are in spec.

Stock is made from a tough injection-molded plastic. The stock interior diameter closely matches the buffer tube for a tight fit. The stock adjustment lever/button has lots of stroke to fit other applications if needed. The buffer tube is anodized aluminum for a long service life.

  • Weight : 469g

You get:

    Compatible with:

    • Standard-spec AR-15/M16 lower receivers

    Installation Difficulty:

    Tools required: Armourer's Wrench required for tightening 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.
