I have a "stock" 54 in 22. I adjusted the sled and have a Diana ZR scope mount with a Leupold rimfire scope living in it.
the trigger is very good but it took me some adjustment to get used to the blade moving back and forth with the sled recoil.
accuracy is outstanding when I do my part.
it takes small game out to 65 yards with ease.
I have purchased the PG2 kit but have not installed it yet.
it falls into the "One of my favorite" category.
