The AK-74 and 105 are both chambered for 5.45X39.
basicaly, the red-alliance thread explained (rather quickly) that choping the outer barrel and using an AK-105 front sight post would do the trick but I really love the fact that front sight is almost sticking to the handguard.
I'm really looking for something more comfortable and practical. I have something in mind but I don't want to make AK purists puke on here
