Which LaRue Railed Handguard Do I Need? *Now with my own setup!*

AR/M4 AR General Discussion

I want a LaRue rail which will cover the LaRue low profile gas block on a carbine length gas system. Which rail length do I need? I believe the 9.0 will leave just a smidgen of gas block exposed? Is this correct?

I need to make sure that the handguard will cover a LaRue low profile gas block, because some other makers gas blocks vary in length. mfingar had a great post on the other site, featuring a mock up of 14.5inch carbines with varying LaRue rails. I compared them to my other carbine with a LaRue rail and noticed that Mfingar wasn’t using a LaRue low profile gas block in his Photoshop mock ups. If anyone has any pictures that would be great as well. Thanks!

UPDATE
A LaRue 9.0 combined with a LaRue gas block will fit flush. Below are two pictures, a before and an after:

Well shit I was just gonna post that very link from the Larue Industry section but it seems you’ve already seen that on TOS.

Hmm…couldn’t tell ya but I’m sure someone will be along here shortly.

ETA:…here’s one w/ a 9.0 and Larue GB…looks to be fully covered.

Here’s another 9.0 posted by Larue…therefore I’m guessing it has a Larue GB under it. Not for sure though.

The 9.0 should cover the gas black if you use a standard carbine length gas block. :slight_smile:

I would like to use the LaRue low profile. Which gas block would fit under the handguards and not be so long as to protrude from a 9.0 LaRue handguard?

LaRue, VLTOR, Daniel Defense and a ‘shaved’ and shortened FSB.

My 10" LMT will sport a 9" DD Lite Rail in the future. I’m going to ‘shave’ and shorten the FSB. I may even cut the FSB essentially in half making it just long enough to conceal the front end of the gas tube. It’ll look a lot like the one I did here for a friend.

It will barely cover it.

Here is what it looks like on one of my ARs!:smiley:

And I shouldn’t leave the other out of this either!
