Rebates are handled entirely by the particular manufacturer and not Buds' themselves and you would start that process after purchase. They will want a copy/image of a upc code from packaging, a sales receipt, and a completed registration form. I'm assuming you're talking about this rebate in particular: https://remington.rebateaccess.com/promotion.php?p=89342 I have the SPS model in .223 and really like it.
