I have a 18 inch Krieger stainless barrel and a Archangle stock I got in a trade. The person said the barrel was short chamber and would need reaming and that the stock and been used. I do not have and way of telling if the barrel is short chambered can some one tell me if there is a way to tell if it is short chambered? The person told me he had the stock on a rifle and did not like it and took it off but said he had to do some filling on the front barrel band to get the trigger group to lock up as he said it would not lock up and thought he was going to damage something so removing some material was the only way to get it to lock up. Does this make the stock useless now? I dont plan on using these myself and would like to sell them but I dont wont to sell them untill I know they are good. Thanks.
