Hello,
I know that you can buy a feed ramp or bullet guide and have it installed in the Saiga rifle to use AK-47 magazines. There are other folks who says you can make this part yourself instead. One of the reviews I read states:
"you can cut a pipe to form a "U" shape and drill a hole threw it and screw it into the reciever."
Some questions I have is if I was to use a pipe instead of purchasing a gun part, what should be the size including the length and width and thickness of the pipe used? What kind of pipe? How much detailed cutting needs to be done to accomplish this?
