Thank You.

That is more complicated than it might seem. Because the front sight (if fixed) is integral with the gas block, you can't just "push it" down the bbl. I suspect you will find it more trouble than it is worth and don't see any advantage for you. If you want a midlength gas system instead of carbine length, you really need to get a new upper or change bbl. and everything but the upper receiver on your current one.
IF , otoh, you want a free float rail, both troy and DD make them without the need to remove the front sights or change the bbl. nut.
