Is there a better precision QD mount than the Thunderbeast CB2?

    I have some HUB compatible cans and I'm considering putting QD mount housings in them -

    In June of 2025, is there a better/more repeatable mount than the Thunderbeast CB2?

    These are all precision-ish rifles that we want to be good out to 600.

    So this is that pattern as well correct?

    Plan B style mounts are 0.9"-24

    The Noveske is not the same as Plan b

    I believe any muzzle device with the threads before the taper is more susceptible to gumming up with carbon. I think that’s why TBAC’s own SR brakes have the threads after the taper.

    I think it’d be cool if TBAC released a Hub SR adapter, with or without the lock.

    My main complaint with CB, which I use and have several of, is that (probably user/install error) they come off with the f'n can and in same cases have simply become direct thread. I've tried rocksett etc but as of yet I've yet to feel secure in the belief there is no chance I'm going to pull a mount with the can outside JB Cold weld, which I have not resorted to but have considered using maybe just a dab...

    If all CB mounts had flats on the rear I wouldn't even consider another system. Since they don't, if I could HUB them all, I might...

    I've had that happen before. I started putting a dab of anti-seize occasionally and have not had it happen sense.

    No that is a 1X16 LH thread for the QD with a tapered mounting surface.

    Similar in concept to the HUXWRX QD mount, but C.A.T. released their QD as open source so there are a few different manufacturers turning out a variety of QD muzzle devices for them.

    Nice thing with a left hand thread, when you go to remove the suppressor it will tighten the muzzle device onto the barrel so the QD mount doesn’t spin off with the suppressor.

    Superior in concept to any of the right hand thread QD mounts.

    Compatible with C.A.T., CGS, and Kobalt Kinetics suppressors.

    I pick up a C.A.T. JL here next week that is a QD model I’ll report back once I hit the range with it.
     
    There are a lot of really good mounting solutions these days.

    I don't think anyone has done comprehensive scientific testing on these mounts to see which ones return to zero the best. I'm kind of surprised that no one has done this.

    Salmon River Solutions makes a mount that has an interface to allow it to be removed should it become jammed in your can. These guys make stuff so i'm confident that the brake will be made to spec but I have no first hand experience.


    I have yet to have an issue with my CB brakes. I keep them lubed during use and break them free after every range session to avoid seizing.

    FYI if you are not set on a brake, TBAC makes exactly one CB muzzle device with some wrench flats; this flash hider:

    It’s down a ways on that page. I think it’s weird that their other CB muzzle devices don’t have flats.

    Edit: upon reflecting, the only reason I can think of for the lack of CB wrench flats is they wanted a “dual use” ability without making the can longer. As in, suppressor QD when leaving the CB device on the gun, and direct thread if you red loctite (or carbon lock) the CB device into the can.

    Edit #2: Note that TBAC has told me that the direct thread version of an Ultra 9 is just red loctiting a CB brake in the can. I do think it would’ve been wise to have a thin wrench flat on there anyway.

    Huh. I didn’t know a Banish 30 Gold and TBAC CB suppressor can use the same CB muzzle device. Cool. My brother own the Banish so I’ll have to let him know.

    Just pin and weld the brake. No mo sticky to the can.

    I have those in 1/2x28, but I don't think they make them in 5/8.

    The salmon river set up is only frustrating in that I have ... enough... TB mounts. Its all I have in me not to sell every one of them and upgrayyedd.
