Retractable sling? Never heard of such a thing.
If it's a magazine tube in the stock it's a bit older and it's probable a model 241 later would be a 550 but it's magazine is the normal front tube. If you really are talking about some sort of retractable sling in the stock, Remington never made anything like that.
Impossible to answer.
