Accidental discharge Mutant
Hey guys this is just a PSA of sorts. I just finished working on a Mutant that would fire when the cocking lever would close. I talked to Dman about it and I have the issue sorted out. If you take the gun apart for any reason it is imperative that you make sure the frame is perfectly lined up with the trigger/barrel band. The gun I fixed was out of alignment. The frame trigger alignment was off ever so slightly it was hard to see with the human eye. This made the Mutant very dangerous. To ensure that the trigger/barrel band housing and frame was in alignment I snapped a line from the muzzle down the rail and to the top of the frame. This eliminated the AD problem. So maybe someone else has a more clever way to align the frame and housing but whatever you use it is important you get it right.

I always measure the gap between the two when I do any work that requires disassembly. My Shorty has a 4.352″ gap between the receiver and scope rail, so I always make sure it remains the same. It’s not really a big deal to adjust the trigger linkage rod, but a good alignment between the two keeps the stock inletting fitting the action correctly. If someone doesn’t know how to properly make trigger adjustments, then as you said they should absolutely keep the gap exactly the same.
