For this money, the closest thing you can do is get a “SlideFire” stock, which is a controlled way of doing the bump fire techniques, and having had one I know it works. Here is my brother shooting a semi-automatic AK74 with the Slidefire stock:

I bet it works better on an AK 74 than an Ak 47, but I think the short stock on the AK makes it difficult to use proficiently.
