Hey all, I am working on a modular bore guide idea. My goal is to make a bore guide equal to anything on the market with the ability to simply swap a couple parts and it will work with a large variety of actions and cartridges. I have made a couple prototypes from Delrin, but they're not where I want them to be. I had an idea to use aluminum for the bore guide and the section that will be in the action. How do you guys feel about a 6061 aluminum bore guide inside of the action? I feel better about the Delrin, but for the idea I am wanting to do, I feel the aluminum will be better for machinability and holding tolerances in a production setting. Any input would be very much valued! Thank you!
