Can't help with the new'ER FHs, but I did some heavy googling you-tubing several years back for a FH for my Hungarian AMD-65. I built two from kits. The AMD-65 has a 12.5 barrel and came with a fat twin ported chunk of steel that was not long enough to pass mustard for the ATF. So, you had to either build it as a pistol or permanently attach something long enough to make the 16-inch mark.
I chose to build one as a pistol without a FH. The other I use an extension plus the factory FH for the rifle.
At the time there were a bunch of people experimenting for designs in an attempt to hide the flash, none worked very well. The bast was one called the pig.
The engineering problem is the shorter the barrel, the less propellant is burned in the barrel before exit.

2)IMG_2845
top AMD-65 with aftermarket FH similar to, but long enough to be legal
middle AMD-65 pistol with thread protector
bottom AMD-63 with 45-deg AK slant FH
3)AK AMD-63 (16inch) with original FH at dusk
4)Noveske KX5
5)AMD-65 with x-inch? extention
Net Net, I watch a lot of dusk and after dark FH vids,, some work better than 90% but all have some flash. A suppressor is the best.
