    I think that is an illusion/camera effect from the angle I was holding the camera at. The should appears to be perfectly square to the bore and the bore appears to be perfectly concentric to the outside diameter of the barrel as well.

    Local (somewhat) smith and fellow PRS shooter is going to take care of it for me.

    Shims are easy to use, no problems there. I presume I'm not the only one who isn't a fan of using a lighter and a razor blade to tediously peel off one layer at a time (if you are lucky) until a muzzle device indexes properly.

    I can't use a crush washer, as this barrel will be used with a silencer.

    Are these threads cut properly?

    Yeah. I don't think the tooling was exactly fresh, and the end wasn't dressed at all. On a positive note, the crown look good. There is a well respect PRS rifle builder I know a couple hours away. Looks like a road trip is in my future.

    Are these threads cut properly?

    Looks like that's going to be the route I take.

    Are these threads cut properly?

    If a shim was able to nest square against the shoulder, I would agree with you. How would you propose I time a muzzle device for use with a silencer when the OD just in front of the shoulder is too large to accomodate a 5/8 shim?

    Are these threads cut properly?

    The threads appear to be perfectly concentric, the thunderbeast muzzle device bottoms out on the shoulder perfectly square. Crush washer is not an option with a silencer.

    Are these threads cut properly?

    For sure it can be fixed. Compass Lake had this barrel for 7 months after quoting me 10-12 weeks lead time. There's no fucking way I'm sending it back to them even if they offered to fix it for free.

    Are these threads cut properly?

    Looks like I have the finest $860 tomato stake around! ETA: I realize this can be fixed. But after a 7 month wait from a smith who closed their doors to the public a few months after I placed my order,my only recourse is to pay another smith to fix it. Beyond frustrating. I'm considering...

    Supposed to have a cut at the shoulder end of the threads, dimension C. https://thunderbeastarms.com/tech/thread-specifications ETA: I think. Again, I am no machinist.

    The Thunderbeast muzzle device is counterbored. It will thread on to the shoulder, and everything appears to be perfectly concentric. The problem is that I need to time the muzzle device, and no off the shelf 5/8X24 shims have a large enough ID to clear the part of the barrel that wasn't relieved.

    Unfortunately, I am neither of those.

    Are these threads cut properly?

    It does indeed. Especially since this is a Bartlein blank that was turned by a smith who, when I ordered it, had a stellar reputation.

    Are these threads cut properly?

    I'm considering just buying an assortment of 3/4 ID shim stock McMaster-Carr in various thicknesses. This barrel certainly isn't what I paid for.

    Are these threads cut properly?

    .624 according to my cheap calipers. The major thread diameter isn't the problem though, its the OD just where the threads terminate before the shoulder. The muzzle device threads on fine. But a peel washer won't seat against the shoulder, and I don't see any shim kits available online that...

    Are these threads cut properly?

    After a 7 month ordeal, that was supposed to take 10-12 weeks, I received my 6 ARC barrel from Compass Lake Engineering. Haven't put it together yet, as work stuff has kept me busy. Went to mock up my muzzle device to see how much timing it needed. Muzzle device will thread on properly and...

    Does this look correct?

    The muzzle device for the Thunderbeast silencer will thread all the way to the shoulder, as it has a relief cut inside in front of where the threads begin, but I'm currently in an internet rabbit hole of searching for a 5/8x24 shim kit that has an ID of .645 or greater.
