Hi Flapp,
Thank you for your helpful information as always.
This one-piece shooting rest was bought many years ago, and no warranty.
I was going to buy ice picks, cut off the tips, and have them inserted in the stem.... what do you think?
The Atlas / B&T Industries bipods and monopods have a lifetime warranty. There is nothing stated on the website that you have to prove ownership/purchase price. Lifetime for many companies means for the life of the product regardless of who owns it or purchased it new. As I said, calling or emailing them to ask isn't a big deal.

Looking at the AccuShot products, it looks like the feet you have may be off-brand replacements, or maybe they were discontinued.
You can buy replacement feet from many resellers, not just AccuShot branded, including one I found called Accu-Tac:
https://www.accu-tac.com/bipod-feetTheir spikes are very similar to the AccuShot spikes sold today, and are only $40 per set.
If you can get yours repaired for cheaper, then that's probably a good deal. If a professional machinist charges you standard labor rates, you're going to be better off just buying new. New will probably last longer, too.
Just my 2 cents. Good luck.
ADDED NOTE *************
One other thing to keep in mind: there are counterfeit Accu-Shot products being made, as there are for most pricy accessories. If you are curious, Accu-Shot will let you send them photos of your item for an evaluation. Email to the same address for customer service. If it's not authentic, then lifetime warranty service would obviously not be an option.
