I’ve done a bunch of pads…$100 labor + cost of pad is fair. I agree with all that has been said above. I too have witnessed many lousy install jobs. You don’t want to skimp to save a buck on a pad install(recipe for disaster).
Here’s an example of my install for $100 labor.
Red Decelerator pad on a Walnut Ruger M77 stock.
Very nice work.
