I've got the same set-up on my AK103 and it works great, but you do have to mount the vertical grip a little more forward to allow for rocking the magazine into the latch. There are also a few other concerns about mounting the weaver rail, but If you're serious, I'll send you an email to help you over the pitfalls I tripped on. I can email a picture, but I can't post one unless someone does it for me.
