    M16-A1 buttcap screw

    Posted by Al on Jun 13th 2020

    These are a necessity for the shorter A1 buttstock. If you Dremel down a long one, the threads get jacked up and it's hard to screw on. "But why do I need a short one" you ask. "The long one worked on my A1 build." When the bolt comes back, the buffer assembly nylon tip will strike the end of longer screw chewing it up. Save yourself the damage and use the right length of screw. Great price too.
