I did this! That's my gun and my photo as well. It's a 1984 Type 54 I got for $150 a while ago.
The bushing comp is made by GunPartsWarehouse and I had to use a broker to get it into Canada. It works decently well (as illustrated by the high-speed image I captured below) and you'd be surprised how much muzzle flip it reduces. Shoot it against a stock one back to back and it's obvious. It would work even better if the exit hole isn't the size of an anti-tank rifle bore, as you can see from the ratio of gas venting from the muzzle and the ports.
