5 weeks ago I sent a Manners T3 to Mr. Ducos(stockdoc) for installation of the Terry Cross KLM Loggerhead cheekrest hardware. Here are a few photos next to a TA. Over all I'm VERY happy with the installation quality and the KLM hardware is just outstanding. Weight is more than the Manners TA installation. With the wide forearm of the T3 it ballances right at the trigger. So this will help since the stock is for a medium weight 338 project.
