I am looking ar installing a 20" rifle length FF rail. I have come down to

Larue 13.2 FF rail LT15-13.2 @ $329

Troy Ind. 13.5 FF rail MRFRX @ $285   (if I can find one)

Yankee Hill Machine 12.5 FF rail YHM-9636 @ $109.95

I will be replacing FSB with Larue LP gas block. I will also be using YHM rail mounted front and read flip up sites.

I need feedback from those who have experience with all three of @ least 2 of these rails.
I need feedback on :

Fit and Finnish
Quality
Ease and sturdiness of installation
(Feel free to add to this list as needed)

Thanks,
David
