I have a 03A3 Remington custom 308 caliber marked "NM". I assume this mark is "national match"?? On the right hand side of barrel it is marked with a "Y". I'm trying to determine the brand name of this barrel. Any help appreciated. Thanks, Rodney

Thanks for the response, but can you tell me what BTT means?
Thanks again
