ok my girlfriend's dad has a model 788 in 223. he is the original owner of the gun. he told me that he has been having problems with the bolt jamming up on him. his magazine spring he says is out of whack and sometimes doesn't work. do you think that he needs a new magazine? i have looked on ebay and other guns sites and they are either too expensive or out of stock and i know that this gun has been discontinued for a long time. correct me if i am wrong. also would a 222 magazine work for a 223? i appreciate the help.
