Product Description
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.
