pws muzzle for my ak47

[tvfreakarms]

Im looking to buy the fsc47 for my romy ak47 build. The romy g came wither original barrel.
I emailed pws and he said that this muzzle device won't work on the romy g ak47 cause the thread pitch is different.
I was wondering if any of u guys own this muzzle break

Yes I had that one and it was a great flash hider and muzzle break. Took it off because I wanted a featureless AK. Is your Romy has a 24mm thread? here's a pic of 14 and 24 mm...

Not sure. I have to check. By the way how would u.knowbif its 14 or 24mm?
Does it say on the the barrel?
