i just built a new ar, and am going to be upgrading it over time. it is an Oly build, with a 16" bull barrel. i need a new FSB that is smaller than the one i currently have so i can fit it under a railed forearm. i dont know the exact dimensions i need for the FSB, so does anyone know the dimensions of an oly bull barrel, as well as a fsb that can fit on one of their barrels, and fit under a railed forearm? sorry if this is confusing |
