Hi Travis,
Welcome to the board!
Short answer to your question - no, it won't matter a bit.
I have handled only the CMP gun from Rock River (read some of my other posts - I LIKE it!) and a friend has one of their 24" flattops and both shoot better'n they have a right to. Don't know which model RR has your fancy, but I like mine as well as the Colts and Bushy match guns in the locker.
FWIW, try service rifle highpower! You'll really like it, I gar-on-tee.
