Well OP was talking about the deafening noise. I was simply responding that noise is not really an issue. In terms of muzzle brakes vs no muzzle brakes, I don't actually see anything wrong with using them as long as you have the right cover for them during adverse weather conditions. It may save some weight in the gun housing due to less need for reinforcement.OK but as far as I know neither OTO nor Mk45 5" nor AK-130 use muzzle brakes:

I know, I was just thinking loud
(actually I was thinking about one of the steps limiting the max. rate of fire of main guns of battleships, which was several seconds recoil plus run-out, something which would be off topic here)
let's say Mk 45 and OTO 5" weigh about thirty tons (EDIT each, not two guns together
and I said 'about') ... what's the weight of PJ-38 130mm?(I used google, saw the weight just in one link which was kinda anti-Chinese)
AK-130 with its autoloader "shop" is way above 100 tons
you mean recoil cylinders or something?

I mean save weight compared to a PJ-38 without the brake. The other gun designs are obviously totally different and so not even remotely comparable.I know, I was just thinking loud

well I asked about specifics of how such a weight saving would be achieved
somehow my more important question got lost (or ignored
and the question has been:thanks anyway

this is interesting ... I assume you provided a translation of what some Chine Navy Officer (the view is cut at the second stripe on the sleeveThe PJ-38 suppossedly has capability to fire guided munition, as well as AHEAD-styled time-fuzed airburst rounds. It needs the muzzle break, since it houses the programming coils that set the fuze once the round leaves the barrel.
presented in TV ... I'm guessing they would also measure actual speed at the muzzle for high accuracy ... would be cool if you posted more on thisThe PJ-38 is supposed to be 50tons (about half the weight of the AK-130), the description at (in japanese) argues that by reducing recoil the muzzle break is one of the changes allowing a lighter construction of the gun.

I've already read about fifty or so tons (but from a link which added some derogatory comments)
well Mk 45 or OTO 5" are about 30t, so is the main difference due to the parts related to an autoloader? (which means 40t in case of an AK-130:
