I've only been working with AR15/M4/AR10s for about 14 years.
AR10 parts across the board are have not yet reached the level of commonality that AR15s have.
When I replaced my AR10 barrel, it was slightly short chambered. Nice looking, melonited, and dirt cheap from a major manufacturer, but needed work to chamber.
I think that the situation will improve, eventually.
If I had a S&W AR10 I would just push through.
