Sadly the only readily available flash hider similar to the one your looking for is the srvv one ($55)
As for the buffer tube srvv has two one for milspec stocks and one for commercial stocks.
The reason these parts are this expensive is that theyre made for real Aks lol
That RIS will work but it will make your rifle more front heavy. LCT make a version of the polymer one (comes on some of their models) if you want a lighter weight and lower cost option.
