Phenomenal Product!
I recently used these for the first time on a Win Model 70 Super Grade, CRF, made in the 80's out of the CT plant. I have used Brownell's Acraglass Gel with steel ferrels for pillars for years on other rifles, but decided to try these adjustable pillars for this project. As the previous reviewer stated, getting the holes drilled precisely is critical. I used a 1/2" bit, then a Dremmel tool to enlarge the holes, so that the pillars just slid in an out of the stock. This allowed me to adjust them precisely before gluing in place and making the final adjustments to the sleeve. What is so great about this product is that you can precisely adjust the pillars to get the action of your rifle to lay perfectly in the stock with a perfect free float. Of course then I glass bedded the action, tang, and floor plate area. If you take your time, the product is very easy to use and the results will astound you as to how accurate a factory rifle can be when bedded properly.
