AR iron sights to mount on FF tube

[SquarePizza]

Trying to find a set of rail mount irons out there, to be used as the primary sighting system. Picked up a set of really crappy sights (UTS... UTG?) off amazon just to give them a try. Big mistake.

Looking around to replace them, I started to notice that most front sights have their height set to be mounted on the gas block, but I will be mounting on a free float tube.

Can anyone point me towards some brands that might work?

**edit**
Context - Grew up a milsurp shooter, only my LR rigs get optics, everything else gets run with a peep.

i drill and tap my float tube for a shotty bead, super fast CQB commando style

I just got a set of Troy Battle Sights, they're really nice. Now I'm just waiting for my MWS to mount them on.

Midwest Industries, and Troy are my favorites.
