Not what I've found at all, Big Stick.
Mine were purchased semi inletted and fitted by my local gun maker. The stocks weighed 18 ozs. or a fraction more ready to bolt up. Neither mine or any other he installed, and we are talking several dozen here, have any significant problems. Only one had a surface crack which was easily repaired.
Here is the best part. It took a grand total of seven weeks from the time I placed the order until the new stock was on the rifle and shooting. Total cost to me was over $100 less than an McMillian Edge, and they are available for almost everything unlike the 24 oz. Edge. They don't reguire pillars as their webbing area is plenty strong. E
