My son has a model seven in 243 Im in the process of refinishing the stock for him. I would like to get him a newer remington trigger the one on it now is realy bad. Will a regular Remington 700 trigger work? Also I would like to see about buying a remington 700 take off barrel for it and was wondering if a good smith could make that work. ? The gun never has been very accurate. Thanks in advance for the help
