Arsenal 24mm thread flash hider or adaptor?

[RyanRevolution]

I've been looking for some flash hider options for my Arsenal SGL21, I wanted to get a Smith Vortex at first but realized that the threading is not the same, are there any other good options besides the Bulgarian 4 peice and the Manticore? I have no experience with either but I like the Manticore cause it is shorter. If not, do you think it would be hard for a machinist to make a 24mm thread to 14mm thread adaptor to fit on the Arsenal?
Thanks

It might work. You will a machinist or a gunsmith to redrill pin hole but I think this would be your easiest bet.
