I recently purchased one of the plastic tactical stocks from ATI for my 10-22. It doesn't fit tight anywhere on the rifle. From the back of the receiver to the stock there is a .070" gap. From the ejector side of the receiver to the stock it's .015", and from the other side to stock is .035". I don't know anything about bedding, but isn't the idea to have the receiver fit the stock like a hand in a glove?????
