Yes both the 11-48 and the sportsman 11-48 are the same gun. The only difference is the sportsman came standard with a plug to limit capacity to 2+1 to comply with hunting laws.
You will need a good gunsmith. The information you seek is not readily available in published material.
I'm not sure, but I think the sportsman has a different barrel configuration. They might be compatible, i say about a 1 in 4 chance of it working. I've never looked at a sportsman pumps barrel, but I've noticed how different model 870 barrels arent always compatible. if the years of the barrel and sportsman are very far apart, you can lessen the chances of compatibility. i suggest you email the Remington website and try to get a professional opinion from them.

You have answered your own question.
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.
NO! The 1187 barrel was for remington shotguns,the auto-5 shotgun is a browning shotgun.

No, a Remington 870 barrel will not fit a Remington 887. The two shotguns have different designs and specifications, including differences in the action and barrel attachment methods. While they may share some similarities, their compatibility does not extend to barrel interchangeability. Always consult the manufacturer's guidelines for specific compatibility information.

No there are ways, it invalves drilling holes to vent gas witch operates the gun.
No, a Remington 700 barrel will not fit a Remington 788. The two rifles have different designs and specifications, including variations in the receiver and barrel interface.

Always consult a qualified gunsmith for specific compatibility and fitting questions.
