Hi everyone,
I am looking for a cheaper alternative gas block for my SASS style build.  The recommended gas block from DPMS is obviously one of theirs: http://www.dpmsinc.com/store/products/?prod=4816&cat=1768.  Unfortunately it runs $110 and that just seems a little stiff compared to some of the other gas block out there.  The barrel I have - their 18" SASS - has an OD of .936" at the gas block and an OD of approximately 1.31" just behind the gas block.  

Anyone know a gas block that can clear that step in the barrel?

Here's one with the right .936 measurement.

Gas Block, Titan, with Two Steel Compression Screws
—exclusive Fulton Armory design, compresssion fit so it can't work loose
—Choose .750" or .936"

.936"
49.95

Looks something like this.

Don't forget your gas tube pins as well.

I too have run into this problem and haven't found any gas block that had the holes in a position that it could be mounted on the SASS barrel.  Not only is the step an issue, but the depth vs. hole location inside the block.  I gave up and bought the GB SASS from DPMS.

I am also looking for a .936 gas block, but not for a SASS.  My barrel is a 20" Krieger.  Has anyone tried one of the Rock River Arms Gas Block?  They have one with a Rail and the Varmint model will supposedly fit a .936 barrel.

I have this on my Krieger/Criterion bbl. .936 20" HB & it works fine. You have to make sure you alien the gas hole to the bbl. gas port.
This looks like who makes them is various bbl. dia..
