Through Marks astoundingly generous barrel give away, I have the joy to build a rifle around a 20" Stealth barrel.
Unfortunately, I do not have unlimited funds so I am trying to make every dollar work to its fullest potential in this build, which brings me to the current dilemma of gas block choices.

This rifle will never be suppressed, so do I need adjustable gas?

If no adjustable gas is needed, what blocks besides the Larue will line up with at least the first and the last dimples?

I have read some people have used the Odin Works blocks but I am unsure if that was the adjustable block or the non adjustable that is half the price of the Larue.

I am open to suggestions with the goal of a quality built upper with enough left in the budget for a sweet trigger like the MBT.

will be running a 15" handguard if that makes any difference to the blocks you would recommend.  


Thank you for taking the time to help me with this.

SLR makes one that lines up the two outer dimples, .450 spacing.  I went with the SLR myself.  They are a little pricey with shipping unless you can get in on one of the sales.

The three below will all line up with the two outer dimples.  Larue uses .450 spacing between the two outer dimples.

SLR Micro Non Adjustable .625 & .750 = .450
Quentin Defense lo pro .750 & .625 = .450
Odin works lo pro .750 = .450

of the non adjustable, is there one that you would recommend over the others?

edit, I read your post with the assumption that you went with the SLR adjustable

You could just order the gas block off of Larues site also.

ETA: Sorry, missed the part in the OP where you were looking at other options as well

I like Geissele Super Gas Blocks, followed cloesly by BCM's gas blocks.



Both are affordable, yet high-quality.

I went with the non adjustable SLR on both my 20in Stealth and 16in PredatAR barrels.

I bought an Odin gas block for my Stealth barrel. It slipped on the barrel wayyy too easy. I could spin that gas block around without much effort. I went with the SLR gas block, and it was a perfect fit. Others may have different experiences with the Odin block on a LaRue barrel. As for me, I won't be making that mistake again.

I know they are pricey vs. other options, but that LaRue barrel should get a LaRue gas block.

It's the nicest gas block I've ever used and you already know it will fit perfectly.

I've used several others.  They work fine too.  But the LaRue is simply "better".  That's my completely subjective opinion.  They are machined beautifully and fit and seal perfectly.  The 3 setscrew mounting makes it rock solid.  And since the barrel is a LaRue, the block takes all of about 1min to have installed and lined up perfectly.

I was torn between LT and "other"
I know LT will fit perfect, but if a SLR or something else fits perfect, and costs $30 less, that puts an MBT in the rifle that much sooner.

I would use the LaRue since the barrel is already dimpled for that gas block.  They are made for each other

Go Larue. I know it's mostly a sales technique, but LT say something to the effect that the barrels are designed to be used with their gas block, and cannot guarantee function/accuracy with other brands. either way, I try to match components whenever possible.

Has anyone tried a Faxon 3 screw loghtweight gas block?

With my first LaRue barrel I went with the LaRue block but cut off the collar.

Faxon confirmed that only one of the three holes in their GB will line up (one opposite of gas port).

One set screw has been plenty sufficient for my uses.

I ended up ordering Larue, figured he gave me a barrel, least I could do is buy small parts from him.

Best option right here. No other will match up and align to Larue's spec
