Educate me on hub mounts RE AB A10

[Choupique]

Im planning to order an AB A10 for a .30 cal hunting can and general purpose other stuff use.

Is having a muzzle brake hub mount advantageous over direct thread? If it is which one should I get?

 

[Q_Sertorius]

I would get direct thread. For me, it’s a matter of weight.

Agreed. Go direct thread. The only advantages to a brake/mount are reduced wear to your can (since brake will take the hottest gasses) and reduced recoil if you shoot the rifle unsuppressed. But if you own a can, I’m not sure why you wouldn’t use it.

Is there any recoil reduction with the brake in the can vs direct thread?

 

[smithjd]

For my bolt / hunting rifles I go direct thread. I used to have muzzle devices on a couple but have removed them to save weight. Might have picked up a little accuracy.

I keep the muzzle devices on semi autos though. As said, if you need to shoot without the can. Also, the can locks on better and shouldn’t come loose if shooting a lot.

Not that I can tell.

Appreciate it everyone.

Since the gas can’t be redirected very far inside the can before it hits the edge of the tube, I doubt it cuts any recoil. The added weight up front of a heavy steel adapter will cut muzzle rise and recoil more than the redirected gases of the brake itself.

Achieving recoil reduction via adding weight certainly isnt worth it to me for this use and definitely not worth spending any money on. I was only going to do it if there were some distinct performance advantages to having the brake vs direct mount. Suppressor life isn't really a concern, I dont think ill ever put the rounds on it for that to matter.

Everyone so far likes direct thread, so I’ll be the minority opinion

I like Plan B style hub mounts on suppressors that get moved from rifle to rifle. My experience is that the thread and taper arrangement repeats better when I mount & remount a can compared to a direct thread (subjective). The integrated break manufactured from a more durable material (ie 17-4 SS) dissipates some of the blast energy away from the first baffle (generally Titanium) which is subject to erosion. If the integrated break erodes, it is an easy replacement without going through a SOT repair shop. Lastly, the plan b break mounted on the barrel protects the barrel threads if something gets cross threaded & makes it more pleasant to shoot without a suppressor.

I just bought this can and have it sitting in NFA jail and have been waying the pros and cons of using a plan b mount. I originally was going to use the can on my ar’s and as a back up/2nd can so I don’t have to swap my Raptor between bolt guns. With no more nfa tax, I figured by the time I set up a hub mount and muzzle devices, I am pretty close to the cost of another A10 that can just be used for my ar-15s.
Long winded way of saying that it really depends. If you plan on not buying more cans, I think it makes more sense to use a HUB adaptor.

The extra weight and expense have never made sense to me. When you think about the tolerance stacking on top of that, ive been a hard no.

The only time it's made sense to me is if youre going between ARs or rifles with different thread pitches. The solution to that problem is to buy more cans.

As far as repeatability, ive had no issues with a shifting zero over 7 different cans and multiple rifles.
