I own a .22 Brownings rifle . Made by Fabrique Nationale. I am attenpting to resore it. The tube that goes through the stock for feeding rounds into the chamber does not retain the ammo rounds. It is a tube with a spring inside. What prevents the rounds from shooting out before inserting the tube back into the rifle. Anny info will be much appreciated.online 1127169@
