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
Ease and sturdiness of installation
(Feel free to add to this list as needed)
One word.... LaRue, I have a 12.0 and a 7.0 and both are well made, not to mention the anti rotation ring is awesome. They are machined extremely well. The only downside is installation is a little hard, but just follow the instructions on this site and you'll be ok.
I've got a Troy 12.0 on one of my ARs. Fit & finish is great. The thing is built like a tank, very sturdy and has some heft (1 full pound).
Installation is super easy, easier than either of your other options, though as your changing out the FSB it really doesn't matter. Yes the LaRue LP gas block fits under it no problem (I'm using one on my rifle).
