Saiga 7.62 parts question

I got a Saiga 7.62 the other day and I need to correct a few things on it. I need to get a new gas block and front sight for it as well as a handguard retaining clip. It currently has the bolt on Carolina shooting clip and I’m honestly not a fan of it. As far as the other two parts are concerned are they good to go aside from not being Russian?

I couldn't find gas blocks on their site but I'm sure the same rules apply as the FSB. Measure your barrel dia. under the FSB. Mine on my 5.56 Saiga is .590". Those at Carolina Shooter's Supply are .571" I got my FSB from Legion USA but I don't know if they have them anymore.

I also couldn't find the gas block you're asking about. Please provide a direct link. The the muzzle brake with FS/GB you linked to doesn't appear to be chrome lined if that matters to you.
