Sorry if this has been asked already but I searched and couldn't find anything. Without getting into the crazy details of this particular rifle and the fact that it can fire separately from the stock; what is the minimum length that you could legally cut down a factory 10 22 barrel to? I am aware that a 12 inch barrel is legal, and an 8 inch barrel would give you an overall length of about 28 inches. Are there any other subtleties within our laws that would prevent someone from doing this? The reason I ask is that I am interested in converting a 10 22 into a light and highly packable survival rifle. Thanks.
