don't do it. If you're looking for long range, bipod stabilized accuracy you've got the wrong cartridge and the wrong rifle.
If you have to have a bipod get a cheap folding steel bipod so that you won't be out much money or have permanent changes to your rifle when you realize how useless the bipod is for a weapon that was designed to be fired on the move with semi aimed fire by ssemitrained conscripts.
The AK is a wonderful weapon, I own a half dozen of them, but a bipod is a waste.
