I’m referring to the rear action screw. I believe it should be a simple lathe project and glue in place with a little JB weld. So far still using the factory synthetic stock. Going to run it to see just how good of accuracy I can get from a budget accuracy build. The PTG bottom metal would factor in the build if and when I go to a Boyd’s stock.Chassis definitely aren't for everyone, I tried the Oryx out on a Howa rifle I was reviewing and really liked it, a couple minor fit and finish gripes but nothing huge.
When you say you're making a bushing for the trigger guard screw, are you referring to the trigger guard retainer screw or the rear action screw? Since you are going to be using the Boyd's have you also thought about running PTG's bottom metal that will allow the use of AICS magazines?
