Will a Remington 1100 stock fit on a sportsman 58?

No, a Remington 1100 stock will not fit on a Sportsman 58. The two shotguns have different designs and stock attachment mechanisms, which means they are not interchangeable. The Sportsman 58 is an older model with a different mounting system compared to the Remington 1100. Therefore, if you need a replacement stock for a Sportsman 58, you will need to find one specifically designed for that model.
