Looks like the design has had a few variations . My front catch design was different . And man, that “sear” adjustment is a bloody nightmare . You make it look easy but having to pull the spring loaded catch forward and locate that tiny screw , though I note all the wrenches were in place before the video started.

I can't find a full review of your JAE 700 or the 700XL (that I am interested in purchasing) . Am I incorrect in saying that you don't have videos of these products?

Why always JAE700? Some videos about the jae100g3 please.
