I have a savage mkII .22 that looks just like that and adco threaded it for use with my spectre. They did a great job and it is very quite with sub-sonic ammo. You will be very happy with the combo and adcos work. I ended up sending in the action and barrel minus the trigger group etc.. It wasn't as bad as I figured to take everything apart just remember where everything goes, sometimes taking a couple pics of before helps as there were several little parts.
