The plastic plug in the buffer in an OLD build recently turned to dust. Literally.  I have seen several of the usual suspects listing complete buffers (out of stock of course) but no replacement plugs. Can anyone recommend a source?   I would hate to spend $30 - $50 to replace the buffer which is still in excellent shape.  Or...

What plastic should I use to make a replacement? Nylon? HDPE?

TIA,

Ken

You could take it to the hardware store and match something up.

Buffer Technologies has just the nylon plug.
Brownells has the same one.

Edit:
Another way to skin it would be to buy an H3
With a Standard and an H3 you can make up an H or H2, so with a Standard and an H3 you actually have all 4 weights.

Thank folks. I was not hitting on all cylinders in my searches yesterday. Perhaps the lack of sun spots was interfering with the Internet or something  Actually I started at midwayusa and (as usual) got rather frustrated.  I have been a Midway customer for almost 30 years. I would have to rate the search facility on their web site as one of the top 5 worst search tools I have come across. Let me get off my soap box...

Why do buffers range from $7 to $140?  Quality differences or snake oil?

The page at Buffer Technologies states
This factory replacement buffer replaces the standard buffer in the AR15 when yours becomes worn or brittle.
so I guess these plugs do wear out.  

Technical question... Is the buffer supposed to contact the back end of the tube during the recoil cycle?

I think for Plan A I will pickup some nylon rod and fabricate a replacement.  I guess I should also add a couple of spare buffers to my parts stock.

Thanks again,

Ken
