First thing.. yes they are compatible.  I have the SA arms clamp on middy kit.

Installation was very straight forward.  The only thing I need to redo was to make sure the gas block sits perfectly inside the hand guard.  Did function checks and looks like she is ready for the range tomorrow.

It was too dark by the time I finished.  Will take some more picture tomorrow.

EDIT: more pictures  :)



Gas block is tight but it fits just fine.

You have to post a pic of the completed project

got too dark last night and all the pictures come out like any other EBR.

Will do as soon as I get home from work - then it's to the range and test her out.
