Buttstock Screw

(2 reviews) Write a Review

Buttstock Screws for all generations of the AR15 / M16 / M16A1.

The original AR15 / M16 (with the Rubber Butt Pad) first had a short screw with no drain hole - Later a water drain hole was added to this screw.

When the M16A2 was adopted in the mid-1980's it used a longer Stock (with a spacer) that required a longer Screw.

We offer 3 options:

  • Original Colt M16 Used take off part - Short with drain hole.
  • New (reproduction) Short with drain hole.
  • M16A2- Longer Screw - New



Made in USA

    Finally got my parts in! It took right at 2 months, but if you're patient, you'll get it! I actually didn't expect to receive my order and had already ordered the same parts elsewhere, so now I have spares! Just be patient people, they seem to be fulfilling orders!

    Needed this screw to restore my Colt AR15 SP1 manufactured in 1978 to original condition. Since I damaged the original and I needed this one with hole in center. Thank you!
