KydeX risers

I have put them on synthetic stocks. Basically you drill 2 holes through the stock, set the riser in place, put the 2 bolts through and tighten it down at the right height and angle. They are ok on a air rifle because of the tendency for a light cheek weld and very little recoil. I wouldn’t put one on a PB that has heavy recoil. They look kind of cheap (they are cheap) but they work.
