I did a search to see if anyone had done this and couldn't find anything. As everyone knows the 1.5 is changed a little and I figured if I have to cut up the stock to mount the Accushot, I might as well go for the CTK Precision. I had an Accushot on a previous rifle and loved it but this design looked appealing because it is inside the stock and would sit lower overall. When I recieved it I was impressed by the function. The spring loading is quick. Anyways, the 1.5 is way different than the instructions that came with it. I read on this forum that CTK is making or already has a updated version of the monopod to fit the new AI stocks. I couldnt find it so I modified the original version.
