My AK has the Tapco furniture and my forward grip is pretty loose fitting. It doesn't affect the functioning, But it bugs me. I was doing a search and wondering how I could overcome the problem without spending a bunch of money on a new set of wood furniture. I like the butt stock and pistol grip that I have, I just need a tighter fitting forward grip with a rail that will mount my vertical grip. The K-Var offering has my attention right now. What would be other options? --Thanks!
