It wouldn’t be bad if the 600 trigger was at the back of the housing like most triggers, but they aren’t. The trigger is at the front of the trigger housing so unless you have freakishly long fingers, the action needs to come back in the stock.
So it took some dicking around, but nothing really hard.

The reversed adl guard works but looks stupid since the 600 trigger sits in the middle of the guard. Hard to see in this pic, but I made my own “adl” triggerguard for the 600/660 where the trigger rides where it should.

* forgot to mention I had a wildcat m7 stock on a 660 in 350RM probably 25years ago, that one used a bottom metal with the factory bottom metal footprint. So that is possible aswell.
