I ordered a Kydex cheek riser for my Savage 10T-SR through Amazon (had points to spend), but also directly emailed Matt through the Mathews Fabrication website to let him know my order and my rifle type. He replied within an hour and made sure to send me the right type of riser with the bolts pre-cut to fit my stock width. It got to me two days later. Outstanding customer service! The website had easy-to-follow instructions and I had no trouble attaching it to my factory synthetic (pronounced "tupperware" all over this board - LOL) stock. Highly recommend this product! He is a USAF veteran, according to his site, which factored into my decision.
