I have a bushmaster with the 16' barrel on it and want to install and DD omega free float rail system. Could i put the 9.0 rail on it and keep the front sight post or do i have to go with the 7.0? Thanks

I assume you mean front sight base, not front sight post.  If so, if the barrel has a carbine length gas tube you will have to use the 7" to keep the front sight base.  If it has a midlength gas tube you can use the 9" and keep the FSB.  I don't even think Bushmaster makes a midlength but I could be wrong.

If you did mean front sight post, you can use any length you want, just remove the front sight base, get a low profile gas block and a detachable, rail mounted front sight.

I would use the appropriate length rail and keep the front sight base.

7" Omega rail is the correct length for the carbine length gas system used on the Bushmaster 16" barreled uppers.
