thanks for your reply guys. well, the maker doesn't have to be someone like rra, lmt, noveske, or any other big name. it could be just any custom shop, to bad i don't know of any who would do a 10.5" 7.62x51. I also thought of going with the 300blacbkout but i've read and heard on some forums that even at 10.5 the 7.62x51 outperforms the blackout. but then that might be personal opinion. and believe it or not, and as silly as some people think, i don't like supressed weapons. so not sure how useful a 300 blackout would be.
