Maybe yes, but it's easy to replace"sniperlabyo"I machine proper size delrine Shim and place it inside the inletting for the stock screw --- it's on the bottom of your photo, over time your shim will get thinner not like the delrine.
The paperboard will be compressed inside the stock until one point. I think even the compressed paperboard will be enough to leave the desired gap, so i don't think it will be necessary to replace over time.
