Can you change the rings to shoot low brass shells in model 1100 3 magnum?

It is not recommended to change the rings on a Remington Model 1100 3 Magnum shotgun to shoot low brass shells. The Model 1100 3 Magnum is designed to shoot high-brass shells, and changing the rings may cause the shotgun to malfunction.

However, if you do decide to change the rings, you will need to purchase a set of low brass rings that are specifically designed for the Model 1100 3 Magnum. You will also need to adjust the gas system on the shotgun to accommodate the low brass shells.

Changing the rings and adjusting the gas system on a shotgun can be a complex and dangerous process, so it is recommended that you consult with a gunsmith before attempting to do so.
