I see Rifle Basix sells an after market trigger with sear adjustment. I have one of theirs I installed (it was a breeze to do) on a Marlin 22WMR with the adjustable sear and it absolutely made that rifle.
If this rifle was mine, I would try adjusting the stock trigger. If it suited me for the role I chose for it leave it at that but if not then I would change it out to a Rifle Basix.
