    I have been under 1/2 " moa with these guns but I had the tube supported by the RSB an not touching the GB .
    I don't know what your goal are or if this is a target build or if you plan to be able to carry it .

    You can achieve 3/4" moa with all the factory stuff attached I have done it on a few 308x39 builds . to ge tbetter than that you have to start giving up some things .
    I see what ya mean. this is gonna be a bench and bipod gun.

    Tortort agreed to sell me a non heat treated receiver. So the plan is to extend the thread on the bull barrel to allow for a barrel nut and a piece that will sandwich between the receiver and the barrel nut that free floats the handguard. And is welded to a modded rear sight block. I got the custom gas block 3D printed but the lowest quote for having it machined was $850 so I will have to simplify it and make it easier to machine.

    The top picture is almost exactly what I had in mind! When I receive my receiver and barrel I can make some measurements and make a CAD rendering of what I'm picturing but that might be 2 more months.

    I really like your cantilever mount, but I think with a milled receiver a standard left side dovetail mount with some locktite will be sufficient. I have some CAD parts of rear sight blocks to play with so maybe I can have a prototype 3d printed.

    I would really like to make a Z type mount that is a direct bolt up to the new magpul zhukov handguard.
