I have had an SLR 107 for a long time and would like to SBR it. Has anyone had any luck using the Dauntless Engineering combo gas block on a 107?  I essentially want to make a 107CR sbr. The Dauntless has a .595 gas journal size. This should be correct for a 104 or 105. I'm just not sure if the 107 has the same size gas block journal.

SLR-107UR is over gassed.  Cut barrel and use a 7.62 krink  booster and it will run liked a raped ape!

Ive heard that. I don't think I will need to mess with my gas port. Mine is a standard full size slr107 and I want to convert it to the 12.5" 107CR. Already have a booster ordered

Which version of the 107 do you have?

The Dauntless combo gas block ended up working well. It slid on tight by hand. I peened the journal with an auto centerpunch and gave it a nice press fit. Turned out well. In case anyone else is thinking of doing the same, it will work on a 107F
