Hey folks. I have a gun in the shop right now. Remington 870 wingmaster, old gun. It's as old as before the started cutting the "u" into the shell carrier to prevent lockup, which I just experienced with snap caps, not fun. The action is smooth up until the point the bolt is in the very rear... The action sticks and you have to force it back and then pulling the action back to home position (forward) takes around 10 pounds of force. The shell latch on the right is sticking a bit so I wonder if buying a new one of those would fix it. Right now I am confused with it. I have no idea why the action is sticking so badly. I took a flashlight to it and all I can see is right when the action becomes sticky, that shell latch makes contact with the action bar. Do I call remington? Do I order a shell latch and *hope* it works?
